UV varnish on Conventional metallic ink

Let us understand how this Conventional metallic inks vs UV varnish chemistry works,

To test metallic inks with UV varnish compatibility , it is important to study this compatibility only in the lab. That requires ink manufacturers to create similar operations on a laboratory scale to what their customers are using or customer can do this in their laboratory.

We did some laboratory test on metallic inks with UV varnish with specified time gap to study the behavior. This article covers the results of the study. This Lab test can be done by the client or ink manufacturer for different drying time to see if there are any improvements in the scratch test. We thank SIEGWERK for providing their lab for testing purpose.

Let us understand about metallic inks:

Metallic ink is a varnish or vehicle containing metallic particles. Common metals used to manufacture metallic ink include copper, aluminum, bronze or zinc. Metallic inks consist of aluminum powder in silver inks (bronze powder in golds), in an offset vehicle system. The primary reason for using a metallic ink is to achieve a metallic sheen in a printed piece. These inks are formulated using either aluminum or bronze (silver and gold respectively) colorant. That colorant, by design will align at the surface of the printed ink film to achieve maximum metallic sheen.

When metallic ink is printed and left to dry, the metallic particles rise to the surface, reflecting light and creating a metallic sheen. It is important to note that metallic inks are opaque. The brilliance is dependent on the leafing properties of the metal powder. These leafing properties can also lead to rub issues. In general, the more brilliant the color, the poorer the rub resistance.

The vehicle or carrier, by design, allows this “float” to occur; in fact it is designed to encourage this surface alignment. There is also a certain amount of penetration of vehicle into the surface of the substrate. Substrates such as SBS board have less “hold – out” so there is more absorption of vehicle into the substrate. Bear in mind that the vehicle is also going to function as the binder of pigment to substrate. The more of the binder that absorbs into the substrate, the less that will be available to bind the metallic colorant to the substrate. What is left is a loosely bound layer of metallic colorant at the printed surface which makes for a “brilliant” metallic look. (Anyone who has run their finger over an unprotected metallic print can attest to the loose bind. See picture .) This also results in rubbing & marking issues, particularly on packaging and covers. Thus the need or desire to protect metallic printed material with a varnish or coating.


Overprinting with varnish will improve the rub resistance, however, the brilliance will suffer since the metallic ink will not be able to leaf, the metallic particles are forced to lay flat. Due to the nature of metallic ink, it is important to be aware that rub resistance issues exist, and therefore, advisable to apply a protective coating on top of the surface. There are trade-offs however, because the protective coating may not react well with the metallic surface causing adhesion problems (such as with a film laminate) or the protective coating can lessen the metallic effect. In most cases an aqueous coating applied in-line will provide adequate protection against rubbing and marking as well as tape “adhesion”. An aqueous coating is low in viscosity and easily flows into the peaks & valleys and interstices in the print surface. The drying mechanism for aqueous coatings is not instantaneous and provides a flexible “plastic” film that flexes and moves as both ink and coating go through their final drying phases. The result is a well bound pair of films that provide adequate rub resistance, but not a high gloss finish. The desire for extremely high gloss on many packages leads to experimentation with UV cured coatings which do provide extremely high gloss, but bring new problems.

One of the most effective methods to achieve intercoat adhesion between the UV coating and a “true” metallic ink is to coat the metallic ink with an aqueous primer coating, prior to UV coating the ink. If an aqueous primer coating is used, it should be applied only after the metallic ink dries/cures thoroughly, or the wet metallic ink will be sealed under the aqueous primer coating and the metallic ink and aqueous primer coating will not dry sufficiently enough to allow the UV coating to achieve acceptable adhesion. An aqueous primer coating (or other UV coating compatible chemistry primer) is most effective in achieving intercoat adhesion due to a couple of reasons. The first is that, in general, UV coating chemistry has very limited compatibility with the lubricant(s) added in the manufacturing process of a metallic ink. During the ink drying process, the lubricant(s) can migrate to the surface and interfere with the UV coating wetting and/or adhesion. Since the level of the lubricant(s) present at the ink/coating interface varies with the degree of dryness of an ink, including the chemistry of

the ink itself and even the porosity of the substrate (which affects solvent retention and drying), the ink/coating interface may always potentially be contaminated with the lubricant(s).

The other most prevalent reason is the generally poor cohesive binding of the metal particles in the ink – the inks are, in essence, tinted varnishes with metallic particles; and, as the varnish dries, the metallic particles migrate to the surface and can rub off easily, creating An unstable surface. Consequently, when the ink is UV coated or laminated, adhesion only occurs on the surface or top layer of the metal particles in the ink.

First of all, there is a radical difference in

1) the general chemistry and 2) the drying/curing process between “conventional” materials and UV cured materials. The different chemistry drives difficulties in “wetting” and “binding” a UV coating to conventional ink and coating. Most coating films shrink slightly as they cure. A UV cured coating shrinks essentially instantaneously which can cause a break in the overall layer at the weakest link. If there is poor surface adhesion of coating to print then the UV cured coating film will easily break away from the surface it’s applied to. (Tape adhesion, scratch tests)

2) Because of the behavior of metallic ink colorant (orienting at the print surface) as the metallic ink sets and dries (either with or without a primer) this leaves this poorly bound layer of aluminum or bronze powder at the surface of the metallic ink film. When a subsequent UV cured coating is applied this loosely bound layer can fail in terms of adhesion of the UV cured coating to the printed film. A primer coating will likely not substantially prevent this as the loosely bound layer forms in the hours after printing and in-line primer coating. If the primer is functioning well, the UV cured coating adheres well and during the UV curing as the UV coating film shrinks, the break-away takes place between the primer and the ink film (the weakest link). A tape adhesion test will demonstrate this. Usually, in these cases the tape will pull a layer of the metallic ink film along with the UV and primer coatings. This is a result of the metallic ink film splitting due to the loosely bound layer of metallic colorant. This failure is not due to a materials failure – it is because all the materials are doing what they are designed to do.


Options

1)There are options to evaluate that will minimize (not eliminate) issues with UV coating adhesion over metallic inks. The key to this is having sufficient binder remaining in the ink film to hold on to the metallic colorants.

The single most influential component in this combination is the absorptive characteristic of the substrate. The more absorbent the substrate is, the more problematic it will be. A lower absorbency substrate keeps more ink binder on the surface of the substrate thereby providing improved binding of metallic colorant in the ink film which improves the overall binding of materials applied over the metallic ink. In order to increase and maximize rub resistance, it is recommended that printers apply metallic ink on coated stock only. The harder and less porous the stock (such as a gloss coated stock) the greater the metallic effect produced. If a customer is interested in printing metallic ink on uncoated or textured stock, the metallic sheen will not be as pronounced because the ink will sink into the pores of the paper. If they are looking to apply metallic ink to an uncoated or textured sheet, the printer may apply two hits of the metallic ink or lay down a thicker film of ink.

20 ) The secondary option is to use a metallic ink that is higher in binder level to begin with. Manufacturers of metallic inks have alternative formulations available which are essentially lower metallic content and higher in oxidative components and binders. This allows a more positive binding of colorant into the ink film. The trade-off here is that there is a lower metallic “luster” proportional to the reduction of metal colorant content. The fast drying time reduces the metallic effect. Longer drying metallic inks tend to have a greater metallic lustre because the particles that reflect light have had more time to rise to the surface of the ink.

A third option is to in-line apply an oil based OPV designed to accept off line UV curable coatings. We tested with OPV and then UV varnish. The result was very good. Tape test passed. The opv we used was duct based with wax content . Twice we did tape test to make sure of report . Both the time the tape test passed. The below pucture shows both the tapes pasted in the same sheet on the edges. 


We will do ine kore test with transparent ink which is again a opv without wax content. If that passes then that would be a good process to evaluate in press. 

We also tested with water based varnish and uv on that. The drying time between metallic and opv/primer/wb varnish was 6hrs -12hrs and again 6-12hrs for uv. 

Metallic ink + water based varnish + uv ; the tape is pasted on the corner of the sheet with metallic ink traces.


A final consideration is that it is usually desirable to minimize the time between printing of the metallic and UV coating the printed film. It is highly recommended that various combinations of these options be tested and monitored under production conditions, as specific printing conditions (ambient environment, fountain solution type and mix ratios, impression, etc.) can and do vary greatly from one pressroom to another.

Additionally we tried with 

Tests for UV lamps, inks and coatings

UV Lamp efficiency

Detex test strips can be used to record the efficiency of UV lamps. The strips are attached across a sheet of paper which is then passed through the press with the UV lamps on and the colour changes of the strips will indicate the profile of lamp efficiency.

Adhesion tape test

The adhesion of an ink or coating to a substrate can be assessed using adhesive tape. The principal is that if the tape adheres more strongly to the ink or coating surface — than the ink or coating to the substrate — then the tape will remove ink or coating. Tapes with various levels of adhesion are used and care is needed to select the most appropriate tape for the purpose. Commonly used standard tapes include:

  1. Moderate adhesive strength: Commonly used by printers and also to test the foil adhesion in foil blocking. 3M ScotchTM range (http://solutions.3m.com) product 3M 616 is made in the USA.
  2. Moderate to strong adhesion: Used by ink makers to test inks and coatings on paper and board. Scapa red tape H101 (www.scapa.com/products).
  3. Strong adhesion: Testing adhesion of UV inks and coatings to plastics. TESA blue tape code 4104 (www.tesa.co.uk)

Method

  1. Lay the print on a hard flat surface (a thick glass slab is ideal) and stick a 5 cm length of the selected tape to the surface with firm thumb pressure.
Since the tape is transparent, we can visually check if the tape is sticking evening without air bubble. The pressure is to ensure the tape is evenly sticked to the printed sheet.
  2. Peel the tape away immediately, quickly, cleanly and smoothly at 90° to the print.

  3. Study both the print and the adhesive side of the tape.
  4. Make an estimate in % terms regarding the amount of ink/coating that is adhered to the tape. 
Always ensure reels of tape are properly stored at ambient temperature (out of direct sunlight and away from sources of heat) and respect use-by dates: adhesive tape deteriorates with age.

Health and Safety first for testing:Throughout the tests wear appropriate clothing (overalls or a laboratory coat), protective glasses and protective gloves (made of vinyl or nitryl rubber) during cleaning. 
Environment: Ensure all waste products, solvents and cleaning materials are disposed of correctly in proper waste bins. Do not mix materials between bins and keep solvents, paper and plastic waste separate.

MEK Test:

Ethanol has a dissolving action, especially on the non-reacted components of the ink. This test assesses the degree cure of the ink film, and consists of rubbing over the print sample with an ethanol soaked cotton pad.

Operation mode:

  1. Soak cotton (or similar) with ethanol. Then place the cotton on the face of the print sample and rub backwards and forwards at constant pressure and at regular speed and amplitude.
  2. Count the necessary numbers of cycles needed to register
  3. The beginning of the ink film deterioration,
  4. The complete destruction of the ink film.

 The results of the test will depend on:

  1. The size of the cotton pad,
• quantity of solvent used,
• exerted pressure,
  2. Deplacement speed on the print sample, • ambient temperature (solvent evaporation).
  3. A specification for the number of cycles to produce this deterioration (initial or complete) can be established after having performed the test on validated prints.

MEK resistance test:

Like Ethanol, MEK has a dissolving power action on varnishes, especially on its non- reacted components. MEK is used to test the curing of UV varnishes only, since it would be too aggressive on UV inks (a test using MEK would not give conclusive results on UV inks).

Refer to the Ethanol resistance test for the application mode which we have mentioned above.

It must be noted that a negative test result cannot only be due to a lack of cure, but also due to an insufficient varnish coating weight.

Scratch resistance (Nail test):

This simple test is not standardised and depends on the printer’s experience. It consists of passing the fingernail over the printed area with a light pressure. A scratch will indicate an insufficient through cure or too soft a film. In this case over varnishing of the print is recommended. Finer nail test is not a standard testing procedure recommended any Certification body but this practice is done globally. Remember, the UV material is not friendly for human skin. There is a possibility the varnish or ink residue get stuck in nail can affect the person or he may accidentally swallow the material .Any testing with UV substances should be done with gloves only. So there is no way of doing nail test.The MSDS if UV inks and varnishes recommend to use glove while operating so with glove nail test is rules out.

Potassium Permanganate Test: Control of the curing of UV lacquers:

Potassium permanganate in aqueous solution oxidises the non-reacted acrylate sites present in the lacquers (monomers or oligo- mers). The optical density of the stains created by the solution on the surface is proportional to the quantity of double bounds that have not reacted in the dried product. This test involves a comparison to a standard value, which can be obtained by carrying the test on a previously validated job.

Operation mode:

  1. With a pipette deposit a drop of solution on the varnished but not inked zones.
• Let the reaction continue for 5 minutes.
• Sponge up the excess with an absorbent paper, with a dabbing method (do not wipe).
  2. Calibrate the densitometer to zero on a varnished but not inked part of the print.
• After having selected the yellow filter measure the optical density of the stain.
  3. Record the value.

Results:

  1. If the reading is inferior or equal to the standard value, the tested product has passed.
If the reading is superior to the standard value, the tested product does not pass (insufficient curing).
  2. Precision: The comparison must always be made against a standard varnished with the same UV lacquer. Any comparison between two different varnishes would be meaningless.

Rub resistance test:

  1. After printing, the product can be subjected to a multitude of strains during the post printing operations, such as cutting, folding, and embossing to name a few. Also during the transformation chain of the product or during its transport to a customer. It can therefore be very useful to simulate these strains using a rub resistance test.
  2. Specifications can be defined in order to detect any possible defaults due to:
  3. Excessive deposit of ink,
  4. Insufficient protection from the UV lacquer (e.g. Low film deposit),
  5. Lack of cure.

 PIRA rub resistance test:

  1. This consists of rubbing the printed surface to test with another piece of substrate, printed or unprinted and need not be identical. The dry rub resistant limit of the printed sample is characterised by a degradation that can be accompanied by ink transfer due to the friction with a blank substrate.
  2. The number of cycles necessary for degradation or transfer to occur measures the limit of resistance. Aspect modification or alteration (powdering, scratches, transfer) can be assessed with a qualitative scale (from 0 to 5) or by comparing with a standard (inferior, equal or superior to standard).
  3. The PIRA rub resistance test is often used by SIEGWERK INK Packaging to assess resistance of print outs designed for packaging. There also exist other tests such as the Sutherland test, which is generally used for paper substrates.

Guideline for printers on the safe use of energy curing printing inks and varnishes


The purpose of this document is to provide guidance on the safe use of Ultraviolet (UV) / Electron Beam (EB) inks and varnishes. It is complementary to the respective supplier’s safety data sheet (SDS).


Energy curing technology is important in the production of all types of printing applications where their fast drying, durable and high gloss finish make them suitable for immediate use.
For this purpose, two major energy sources are used: ultraviolet lamps and electron beam. Both emit energy, which directly converts appropriate reactive liquids to solids.

  1. Product hazards
    UV/ EB curing acrylate can cause skin and eye irritation.The effect on skin can depend upon intensity and duration of contact as well as individual susceptibility. Certain individuals may develop sensitisation or allergic reaction after repeated exposure and will need to be removed from the source of contact.
    Since energy-curing products are not corrosive, their presence on the skin may not be immediately noticed. This increases the potential for skin irritation and normal day to day activities may spread the effects to other parts of the body.
    Persons known to have a history of skin sensitisation should not be employed using these materials.
    Some products may be eye irritants and care has to be taken to prevent these products from coming into contact with the eyes as well as more sensitive areas such as mouth and nose.
    With high speed printing presses small ink droplets may become airborne. The mist formed has the potential to present a hazard from inhalation and may be irritating to the skin or respiratory tract or sensitising to the skin. It is essential that the presses have appropriate extraction installed.
  1. Safe handling
    Skin contact should be avoided.
    Long-sleeved protective clothing should provide adequate protection and should be changed immediately if contaminated. Contaminated clothing should be laundered at a commercial laundry before re-use. Do not take contaminated clothing home for cleaning.
    Gloves that are resistant to energy curing products must always be worn when direct contact with the material is possible. For advice on the safe use of gloves, refer to suppliers’ safety data sheets and technical information from glove manufacturers.In the event of accidental contamination the skin should be washed with neutral pH soap and water. Solvents must not be used as they will degrease the skin and possibly promote irritation. In case of accidental skin contact avoid concurrent exposure to the sun or other sources of UV light, which may increase the sensitivity of skin.Recommended barrier creams should be applied to clean skin and should not be applied after contamination.

Safety glasses or other adequate eye protection must be worn whenever handling any type of chemicals. In the case of splashing into the eyes, wash thoroughly with water ensuring that contact lenses, where worn, are previously removed. Refer to the SDS and seek medical advice immediately. Avoid sources of light that may increase eye sensitivity.
UV lamps emit high intensity UV (and visible and infrared) light. Therefore it is necessary to ensure that suitable screening is used to protect the operators from skin and eye effects. In addition, ozone may be generated from the lamps. Thus it is essential that UV lamp housing extraction is sufficient to provide good working environmental conditions.
EB systems emit ionising radiation and must be adequately shielded and meet any national ionising radiation regulations or Approved Codes of Practice.
Accidental ingestion may occur through poor working practices. Therefore, eating, drinking and smoking should be prohibited in the immediate area where these products are being handled. Hands must always be washed before break periods.

  1. Spills/Disposal
    Good levels of hygiene must be maintained and spillages must be cleaned up immediately.
    Energy curing systems remain wet unless exposed to the appropriate energy, so spillages and accidental contact can spread to other places. Ensure that no material is accidentally transferred to any parts of equipment.
    In common with many other materials, the uncured products are typically classified as “hazardous waste” for disposal purposes which should be done according to national regulations. It is not anticipated that they would have an adverse effect on the disposal process and may provide a positive energy source in the case of incineration.
    Any used wipes from clean-up or wash-up operations should be placed immediately in a separate, labelled container to prevent accidental exposure of other personnel in the work area and treated appropriately by waste disposal regulation or special laundry.
    A large spillage should be contained and removed with non-combustible material such as sand or earth. The spill area should then be thoroughly washed with hot detergent solution. Since energy curable materials will not dry by evaporation, it is important that any spill be completely removed. Otherwise, these materials will remain wet and a continuous source of exposure.
  1. Conclusion
    All types of UV/EB products can be handled safely as long as the user is trained in and observes all recommended safety procedures.
    Always refer to the supplier’s Safety Data Sheet and take appropriate actions. Seek guidance if necessary. It is the legal responsibility of users to carry out risk assessments based on their specific applications. Attention must also be paid to any specific national legislation, code of practice or guidelines.

BOPP VS CPP FILMS

BOPP film

It is a very important flexible packaging material with a wide range of applications. BOPP film is colorless, odorless, odorless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency. The surface energy of BOPP film is low, and corona treatment is required before gluing or printing. However, after corona treatment, BOPP film has good printing adaptability and can be overprinted to obtain exquisite appearance, so it is often used as the surface layer material of composite film. BOPP film also has shortcomings, such as easy accumulation of static electricity and no heat seal-ability. On a high-speed production line, BOPP film is prone to static electricity, so it is necessary to install static electricity remover. In order to obtain a heat-sealable BOPP film, heat-sealable resin glue, such as PVDC latex, EVA latex, etc., can be coated on the surface of the BOPP film after corona treatment, solvent glue, or extrusion coating or The method of co-extrusion and compounding produces heat-sealable BOPP film. The film is widely used in the packaging of bread, clothes, shoes and socks, as well as the cover packaging of cigarettes and books. The induced tear strength of BOPP film is improved after stretching, but the secondary tear strength is very low. Therefore, no cuts should be left on both ends of the BOPP film, otherwise the BOPP film will be easily torn during printing and lamination. After BOPP is coated with self-adhesive, sealing tape can be produced, which is a market with a large amount of BOPP.

BOPP film can be produced by tube film method or flat film method. The properties of BOPP films obtained by different processing methods are different. The BOPP film produced by the flat film method has a large stretch ratio (up to 8-10), so the strength is higher than that of the tube film method, and the uniformity of the film thickness is also better.

In order to obtain a better overall performance, it is usually produced by a multi-layer composite method during use. BOPP can be compounded with many different materials to meet the needs of special applications. For example, BOPP can be compounded with LDPE (CPP), PE, PT, PO, PVA, etc. to obtain high gas barrier, moisture barrier, transparency, high and low temperature resistance, cooking resistance and oil resistance. Different composite films can be applied to oily food.

CPP film

It has the characteristics of good transparency, high gloss, good stiffness, good moisture resistance, excellent heat resistance, and easy heat sealing. CPP film is printed and bagged, and is suitable for: clothing, knitwear and flower packaging bags; document and photo album film; food packaging; and metallized film for barrier packaging and decoration. Potential uses also include: food packaging, candy packaging (twisted film), pharmaceutical packaging (infusion bag), replacing PVC in photo albums, folders and documents, synthetic paper, self-adhesive tape, business card holders, ring folders And standing bag composite material.

CPP has excellent heat resistance. Since the softening point of PP is about 140°C, this type of film can be used in hot filling, retort bags, aseptic packaging and other fields. Coupled with excellent resistance to acid, alkali and grease, it becomes the first choice for bread product packaging or laminate materials. It is safe in contact with food, has excellent performance, does not affect the flavor of the food inside, and can choose different grades of resin to obtain the required characteristics.

As mentioned above, the production process of cast film generally adopts the T-die method. The characteristics of this method are:

(1) The casting method eliminates the film blowing stage of the tube film method, which is easy to drive and has less waste;

(2) In the production by casting method, the chemical molecules are arranged in an orderly manner, so it is beneficial to improve the transparency, gloss and thickness uniformity of the film, and is suitable for advanced packaging;

(3) The casting part adopts electric up and down swing and back and forth movement structure, which is easy to operate;

(4) The corona part is air-cooled and water-cooled, and the product is not easy to deform.

The extruder first melts the raw material resin, and the molten resin is cast on the cooling roller with a smooth surface through the die to quickly cool into a film. After thickness measurement, traction, corona treatment, and flattening, cut off the thicker edge material, unfold and wind it into a film roll again.

The main points of CPP cast film production process

The T-type head is one of the key production equipment. The design of the head should make the material flow out evenly along the entire width of the lip. There is no dead angle in the flow channel inside the head, and the material mold has a uniform temperature. It needs to consider the material rheology. Many factors including behavior. To use precision machining heads, the gradual reduction manifold hanger heads are commonly used. The surface of the cooling roller should be finished, the surface roughness should not be greater than 0.15mm, the speed should be stable, and the dynamic balance performance should be good to avoid longitudinal thickness fluctuations. Use β-ray or infrared thickness gauge to monitor film thickness to achieve satisfactory thickness tolerance. To produce a qualified cast film, not only must the raw material be adjusted, but also the processing conditions must be mastered.

The biggest influence on film performance is temperature. As the temperature of the resin increases, the longitudinal (MD) tensile strength of the film increases, the transparency increases, and the haze gradually decreases, but the transverse (TD) tensile strength of the film decreases. The suitable temperature is 230~250℃. The air knife on the cooling roll makes the film and the surface of the cooling roll form a thin air layer, so that the film is uniformly cooled, thereby maintaining high-speed production. The adjustment of the air knife must be appropriate. Excessive air volume or improper angle may make the thickness of the film unstable or not stick to the roll, causing wrinkles or patterns to affect the appearance quality. The temperature of the cooling roll increases, the stiffness of the film increases, and the haze increases.

If the internal additives of the raw material precipitate on the surface of the cooling roller, the machine must be shut down for cleaning to avoid affecting the appearance of the film. The cast film is relatively soft, and the pressure and tension must be adjusted according to factors such as film thickness and production speed during winding. Otherwise, it will produce ripples and affect the flatness. The choice of tension depends on the tensile strength of the product. Generally, the greater the winding tension, the product after winding is less likely to experience roll slack and deviation, but it is prone to ripples at the beginning of the winding, which affects the smoothness of the roll. On the contrary, the winding tension is small and the initial effect is good, but the more the winding is, the more the film is slack and the deviation occurs. Therefore, the tension should be moderate and the tension should be kept constant.

Process characteristics of multi-layer co-extruded cast film:

In order to improve film performance, reduce costs, and meet user requirements for multiple uses and high performance, multilayer composite films have developed rapidly, especially in developed countries where living standards are relatively high, environmental protection is emphasized, and food shelf life and quality are required to be extended. Multi-layer copolymerized cast film is also one of the multi-layer films, which has changed the problems and drawbacks of CPP film products that have single performance and cannot meet the requirements of the market.

1. Universal type: Multi-layer copolymerized cast film can be used for different purposes and designs, such as bread packaging, clothing (especially underwear, pants) packaging, fruit packaging, etc. on automatic packaging machines, or used with BOPP after printing The film is compounded into a BOPP/CPP two-layer film, which is used for packaging of clothing and dry food (such as fast food noodle bags, bowl covers, etc.). The general-purpose structure is copolymer PP/homo PP/co PP or homopolymer.

2. Metallized type: The surface of the product is required to have strong adhesion to the vapor-deposited metal (such as aluminum), and it can still maintain good dimensional stability and rigidity after vapor deposition. The other surface has a lower heat sealing temperature and Higher heat sealing strength, metalized structure is also PP copolymer/homo polymer PP/PP copolymer.

3. Cooking type: Two-layer copolymerized CPP used for cooking, which can withstand cooking and sterilization at 120℃ and 15MPa pressure. It not only maintains the shape and flavor of the internal food, but the film will not crack, peel or bond, and has excellent dimensional stability. It is often compounded with nylon film or polyester film, and is packaged with soup foods, meatballs, and dumplings. For food or processed frozen food before eating, the cooking type three-layer PP film structure is co-PP/co-PP/co-PP.

4. High-temperature cooking type: packaging roasted chicken, roasted ribs and jam, beverages need to be 121-135 ℃ high temperature sterilization three-layer copolymer CPP film, of which copolymer PP requires better performance than the general cooking type copolymer PP. In addition to the three-layer film, there are also five-layer packaging with cast barrier properties. Its structure is: PP/adhesive/PA/adhesive/copolymer PE; PP/adhesive/PA/adhesive/EVA; PP /Adhesive/EVOH/Adhesive/PE; PP/Adhesive/EVOH/Adhesive/EVA; PP/Adhesive/EVOH/Adhesive/PP.

OPP film is a kind of polypropylene film. Because the production process is multi-layer extrusion, it is called co-extrusion oriented polypropylene film (Oriented Polypropylene Film). If there is a process of biaxial stretching in the processing, it is called Biaxially Oriented Polypropylene Film. Compared with the co-extrusion process, the other is called Casting Polypropylene Film, which is relatively thick.

OPP film

The current applications in packaging include self-adhesive labels, in-mold labels, winding labels and wet glue point labeling. The latter is mainly used in beverage and alcohol labeling abroad. In the past few years, it has gradually been introduced into the Chinese market from Europe, and its application fields include food, chemical, and daily chemical products. In addition, OPP is applied to shrink film like PE and PVC film. The advantages are high transparency, good gloss, high shrinkage and shrinkage stress, but poor heat sealing performance and heat sealing strength, high shrink temperature, and narrow range.

For the relatively saturated and homogeneous daily chemical products in the market, appearance is everything. The first impression determines the purchase behavior of consumers. Shampoo, shower gel, detergent and other products are used in warm and humid bathrooms and kitchens. Labels are required to withstand moisture without falling off. Their squeeze resistance must match the bottle body. At the same time, the transparent bottle body is suitable for adhesives and The transparency of the label surface material puts forward stringent requirements. Compared with paper labels, OPP labels have the advantages of transparency, high strength, moisture resistance, and resistance to falling off. Although the cost is increased, it can get a good label display and use effect. With the development of domestic printing technology and coating technology, the production of self-adhesive film labels and printed film labels is no longer a problem. It is foreseeable that the use of domestic OPP labels will continue to increase.

Understanding Corrugated Boards

The below content was shared in PressMan PQM group. Group Joining Link: https://chat.whatsapp.com/Iix9aZdFmFHCNU8aTwqOba

Understanding corrugated board – Material breakdown

For simplicity, flute profiles explained (FPE) will focus on single wall B flute corrugated board, being the most popular material used in the FMCG market sector.

So, what is a ‘special flute’ or ‘reduced flute height’

In short, it’s a fluted medium (5) that’s reduced in height (6) compared to it’s original B flute height (6) running along the chop or length of the sheet (4)

1

 

Yes, off-set bends create a flat top & bottom.

A ‘squarer internal fit’ and used widely in the Whisky / bottling industry.

More about this later in the series.

Off-set bends can have an adverse effect o top load (BCT)

Yet the ECT value will remain the same!

The box (A) with off-set bends (x & y) under compression the initial load is supported by the 2 full depth panels along the bends (x)

As the top load / force increases the box starts to ‘buckle’.

The pressure increases and accelerates through the inner flaps (y) and failure occurs = unequalled load bearing

This makes sense.

If all 4 panels box (B) bends (z) support the load initially, the load required to ‘buckle’ the case is increased = equal load bearing = improved performance

2

Corrugating rolls don’t classify by flutes type only, there are many other importent specifications you need to know before choosing your rolls.

Flute hight, pitch, coating thickness, tip radius, and valley radius all of them play a role in your corrugator performance and final board quality.

 

Bend Stiffness Test

4

Insights – an underutilised test method?

The test is useful in determining auto case erection parameters and / or glitches

Critical for high speed automated packaging lines

Bend stiffness measurements can be written into the supply specification to

  • ensure pack design machine compatibility
  • aid runnability / machine efficiency / manufacturing output
  • deter competitors / safeguard supply

 

Example 1

A supplier might in all good faith ‘upgrade’ the material only to find the *bend definition isn’t good enough because the board itself is too good (over stiff)

*Poor bend definition can cause folding snags on automated packing lines

Example 2

Regular cases manufactured with little or no corrugator bend definition or conversion bends can cause problems on auto case erectors and case sealers

Remember, some case flaps (0201 type cases) need to ‘fold back’ to allow automated filling before they fold forward to close.

 

ECT or bust…

ECT is directly linked to BCT – Box Compression Test

3

BCT – Some insights

Loads applied in the laboratory are somewhat idealised.

Being applied slowly through smooth flat surfaces for short periods.

In the real-world loads are applied much more haphazardly, with overhang on pallets, brick stacking, open boarded timber slats, point loading etc., just to name a few!

Also, dynamic loads are met when pallet loads are moved.

These combine and significantly increase the load stresses on the bottom case beyond the load that apparently is sitting on that case!

Cases can also show creep.

If a case under laboratory compression supports 300 kg, it’s likely it will creep if a load of 150 kg or more is placed on it.

This means that although the case may appear to stand up under the load for an hour, a day or longer, it is actually collapsing very slowly.

The higher the load the faster the collapse.

To allow for the real world a safety factor is applied to ensure the case will actually perform satisfactorily and safely.

5

*The safety factor will increase (or decrease) dependent on the product and distribution criteria.

 

Board testing methods and procedures

All tests should be carried out under the same conditions to ensure accurate comparable results.

Board conditioning

Paper and board will take in or give out moisture depending on the ambient air temperature and relative humidity (RH)

As 1% extra moisture in a case will drop its compression strength by between 10 and 15% it is important that all strength tests are done under the same moisture, atmospheric conditions.

Why is board conditioning important?

Water interferes with fibre bonding so the moisture content of the sheet affects many paper properties, especially strength properties.

Temperature also affects results because air can hold different amounts of water vapor at different temperatures.

Within the industry the standard conditions equate to around 8% moisture in the board and are 23°C and 50% RH

Board also lengthens approx. 0.125% for every 1% increase in moisture

Relative Humidity (% RH) is the amount of moisture vapour in the air expressed as a percentage of the moisture that the air could hold at that temperature.

So, if you’re conducting tests make sure you do them under the same laboratory conditions 23°C / 50% RH.]

Glue Applicator Speed Vs Corrugating Roll Speed

6

it’s one of the most important points to check and adjust in your corrugator, any small change on the glue applicator speed effect directly on the board quality.

In this photo, we can see the effect of speed on the flute tip.

Environmental Ready Packaging (ERP)

8

Easy to collapse, easy to recycle

Just like the 1.9L & 1.9W all Environmental Ready Packaging (ERP)

> Folds flat (all ERP fold flat the same way)

> Maximises space in wire crates, minimises movements, maximises payloads

> 100% recyclable

Here’s a recap on the ERP magnificent 7

> Easy to identify

> Easy to open

> Easy to decant (If its brown, it’s easy to decant)

> Easy to shelf (If its white, it’s easy to shelf)

> Easy to see, easy to pick, easy to shop

> Easy to collapse

> Easy to recycle

Environmental Ready Packaging (ERP) combines environmentally sustainable materials with simple cost-effective packaging designed to offer the very best value from producer to user.

ERP meets the customer supply criteria using the minimum amount of material offering maximum amount of protection at minimal cost

ERP recognises the importance of the environment and is 100% recyclable

Leading the development in clever, simple, value adding innovation.

Board quality is the foundation for corrugated excellence and therefore the board used directly affects print results. New materials and improved technologies make it possible to manufacture corrugated board to a much higher standard and realize cost savings on glue consumption and required drying capacity.
