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 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.

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.
