PE COATED BOARD
Food grade paper board is commonly and wildly used in our daily life. It can be individually molded into a paper cup or a food box but in most cases it needs to be processed first—Coating (Laminating) can make it achieve a better function performance.
PE coating(Lamination) can improve the waterproof, abrasion, heat and pollution resistance of the coated paper, as well as improve the gloss and touch of the coated paper, and enhance the durability and folding resistance of the coated paper.
The technology is widely used in various fields. Printed materials, color box packaging, book covers and other fields, such as high-grade color printing albums, business cards, advertising leaflets and other printed materials, gift boxes, wine boxes, cosmetic boxes and other color box packaging, book covers, book jackets, album covers and other fields.
Ordinary paper is composed of wood fibers, which is very absorbent and does not perform well in high humidity environments. PE coated paper has hot-melted PE evenly to the surface by using a laminating machine to form a film. So it can prevent water immersion and has better waterproof performance and leakage performance, no leakage, oil, acid resistance, better protection of cups / bowls of food inside not to leakage, outside the dip situation. Due to its waterproof and oil-proof, it is mainly used for food cartons, paper cups, paper bowls and packaging, also can be used as industrial waterproof paper.
Depending on the usage, we can choose different paper base and coating(lamination) methods. Nowadays in Chinese market, the commonly used food grade paper is divided into two categories: Uncoated paper (PCM/ FK1/ FKO/ PCB/ FNO/ FCO) and Coated paper (GCU/ PCC/ PCB/ PCKB/ FVO).
Uncoated food grade paper base
Uncoated food grade paper has a uniform surface and good stiffness, without a fluorescent. Good adaptability to post-processing, satisfying various packaging processes such as coating(lamination), cup making and other processing techniques. Through the QS certification license, FSC / PEFC certification, the products are sent to the inspection every year, in line with the FDA21 Ⅲ and other European and American packaging directives, regulations and requirements.
PCM/ FK1/ FKO/ PCB are all cupstock paper, can be made into paper cups, hot drink cups and cold drink cups. With one side PE (hot cups), it can be used to hold hot water, tea, beverages, milk; With two side PE (cold cups), it can be used to hold cold beverages, ice cream,etc. The main difference is they have different gsm and bulk thickness, so you can choose the most suitable products according to your needs.

You may find APP/BOHUI both have the Allyking Cream/GCU ， yes ,it is true .
Since BOHUI paper mill was acquired by APP Group, their machinery, equipment and teams have been slowly integrated, and the quality of paper produced by Bohui Paper has gradually improved to be comparable to that of APP. This is undoubtedly a good thing for consumers.
Since plastics are such a prominent material around the world, bio-plastics were developed to combat the issues we face with conventional plastics. The most commonly used compostable bio-plastic is a clear bio-plastic material called polylactic acid (PLA). These products can look similar to traditional petroleum plastic and although they may look identical they are very different. The main difference is that PLA degrades faster when it is exposed to the right environmental conditions (composting) while conventional plastics can take decades to degrade.
PLA (Polylactic Acid) is a biodegradable material with excellent degradability. However, paper cups made of PLA lamination are only suitable for industrial degradation, and the degradation process causes more serious pollution to the environment.
PLA bioplastics are made from polylactic acid, a transparent thermoplastic aliphatic polyester made from renewable resources. Bio-based plastics like PLA are derived from biomasses like corn, sugarcane, seaweed, or even shrimp shells. PLA is also biodegradable, meaning it breaks down in natural environments and only leaves behind biomass, carbon dioxide, and water.
It’s important to note that not all bio-based plastics are necessarily biodegradable, and vice-versa. PLA bioplastics are the only commercially available bioplastics that are both bio-based and biodegradable, and they are one of the few bioplastics suitable for 3D printers.
Compared with the traditional polyethylene PE laminated paper, PLA laminated paper not only serves as waterproof, oil-proof, and heat-insulating, but also has the characteristics of non-toxic, fully compostable and biodegradable.
It is 100% bio-based, conforming to EN13432 and ASTM D6400. In composting environment, it completely decomposes into carbon dioxide and water, environmentally friendly, non-toxic, low carbon release, non-toxic and harmless to human body, organisms, and the environment, and safer to use.
As the global fever to protect the environment gradually strengthens, various industries will create a green recycling industry to realize high-quality sustainable development. In the context of the "carbon peak", "carbon neutral" era, more and more paper companies in the low-carbon environmental protection, green development focus on efforts.
In 2020, APP China officially launched the "Zero Plastic" paper cups and paper products. The product is completely free of plastic components, with recyclable, industrial explanation, compostable and other environmental characteristics, and also has good waterproof and impermeable performance, which can replace the traditional plastic coated paper cups. The coating can effectively block hot water, coffee, milk tea and other liquids, with good barrier properties, sealing resistance, printing effects, recyclability of water-based coating.
Our “Zero Plastic” main products are as follows
1.APP - OPB:
(paper base is APP-Allyking Cream GCU)
GSM: GCU paper base+5g Kit 6
GSM: GCU paper base+10g Kit 12
The technology focus an unique coating technology which provide the coated board enough oil resistance, zero odor. OPB also focus three key demand in the market: repulpable (Being recycled in paper or board stream), bio-degradeable, compostble.
Fluoride products like PFOS, PFOA are harmful to the health in despite of its best oil resistance performance, we have to find better solution so as to reduce the overuse in the world. And now more and more governments require to stop using the paper products with Fluoride especially for food contact paper. Fluoride-free Oil repellent agent instead of traditional products.
OPB has below four main advantages:
1.Safety: 100% all-wood pulp manufacturing; no silicone oil and fluorine substances; in line with China's national standards (GB4806.8/GB9685) and international certification (FDA, POPs, 1935/2004/EC)
2.Wide range of applications: Wide range of oil-proof, oil-proof grade up to kit 6-12, used for the packaging of containing goods; High temperature resistance, can meet the domestic microwave heating; good water resistance, used for frozen/chilled food packaging and cold chain storage and transportation, as well as various types of food packaging
3.Eco-friendly: Recyclable, using only water-based dispersion coatings, with non-plastic properties, can be recycled without special treatment; degradable, meet GB and EU degradation requirements; non-fluorine and non-silicone, with unique barrier technology.
4.Good post-processing properties: Positive to meet the offset printing, water-based coding and non-water-based coding and other processes; excellent gloss performance, good dot reproduction effect, the finished product color is bright. High looseness and stiffness to meet various packaging processes such as die-cutting, creasing, etc., with good molding performance.
OPB which meet food grade like EC, FDA, GB9685; fluoride-free; plastic-free; silica-free; mineral wax free. It is suitable for the direct production of food packaging cartons, food and beverage grease-proof paper packaging, stamping lunch boxes and so on.
The oil-proof grade is expressed in terms of kit value: the higher the kit value, the better the oil resistance of the cardboard. And compared with pulp molding product, it is low cost and high efficiency. Kit 6: Packaging of French fries, doughnuts and other fried food products Kit 12: Direct packaging of chocolate, ice cream and other products.
2.APP - EPP
In recent years, the international community has increased its efforts to control, from "Plastic Restriction" to "Plastic Prohibition", and introduced a series of policies or decrees. For the sake of sustainable development, APP China launched EPP which is a special process to create products. EPP is a water-based dispersion coating, which can be processed directly on the paper machine or on top of the coated fabric; it is degradable and recyclable, which is more environmentally friendly than PLA/BIO, which can only be degraded and not recycled.
Compared with the traditional PE lamination paper, the process of zero-plastic paper cup paper EPP is to apply a layer of barrier coating on the original paper, which is used to isolate water and other liquid substances from wetting the original paper, and then apply a layer of heat-sealable coating on top of this so that it can be loaded with all kinds of hot food.
Burying PE/PLA/EPP paper cups and OPB cardboard in the open space. Allowing these to degrade naturally. After each digging of observation, continue to bury these back.
After 245 days, EPP had completely degraded, OPB had a very small amount of debris, PLA fibers were partially susceptible to degradation and membrane fragmentation occurred, and the membrane of PE was essentially intact.
EPP (Environment Protection Polymer) in-line coating, instead of single and double shower, reducing the intermediate link and improving the production efficiency. Its best feature is that the paper comes with waterproof and impermeable properties. It is suitable for directly making all kinds of paper cups, paper bowls, lunch boxes, soup buckets and other take-away catering packaging.
EPP has excellent barrier properties, waterproof, oil-proof, and can be used to make a variety of paper cups, paper bowls, lunch boxes, soup buckets, etc., holding ready-to-eat drinking water, tea, beverages, milk, milk tea, coffee, etc.
EPP can achieve good water and oil resistance and ultrasonic and heat sealing self-adhesive effect without additional coating. Containing coffee, milk tea, drinks and other liquids can reach more than 4 hours without leakage. Does not contain any plastic, completely recyclable, industrial degradation (100%), re-pulping, compostable, safe and environmentally friendly, in line with the development trend of green packaging materials.
EPP zero-plastic coated paper has stronger friction than PE, Ink is easily rubbed and become dirty after printing. So for EPP zero-plastic coated paper we recommend to use flexo printing. In the printing process, special attention need to be paid to ink drying and printing pressure not being too high. It is best to dry under high-temperature and rewind under low-temperature. Besides, the PH value of the ink should be controlled between 8.5-9.5.
