Disposable paper cups are frequently used in People's Daily life. In order to enhance the safety of disposable paper cups, Guangdong Kaicheng Paper Combines PLA coated paper and environmentally friendly non-toxic paper containers. Natural corn as raw material.

At present, the disposable paper cups sold on the market are mainly divided into three kinds: one is made of white cardboard, mainly used to hold dry things, can not hold water and oil; The second type is waxed paper cups, which are waterproof and thick because they have been soaked in wax. But the wax, which contains cancer-causing polycyclic aromatic hydrocarbons (PAHs), melts when the water in the cup rises above 40 ° C. The third is now widely used paper plastic cup, the outside is a layer of paper, the inside is a layer of drenching paper. The quality of drenching paper determines whether harmful substances will be produced during the use of PLA drinking paper cups.

An industry insider told reporters that at present, the raw materials of disposable paper cups, the prevailing industry is the low price of mixed pulp paper, but the worst disadvantage of this pulp is that it is easy to deform in cold and hot, and the joints are easy to crack. And some domestic paper cup manufacturers mostly use sugar cane pulp, this raw material is about 1/3 cheaper than wood pulp, but sugar cane pulp produced by the large volume paper cup is not as strong as wood pulp paper cup, in some high temperature liquid, easy to crack cause safety risks. At the same time, sugar cane pulp color is darker, some undesirable manufacturers in order to achieve the effect of beautiful products, it is possible to beautify by using bleach or phosphor.According to insiders, PLA coated paper is made of 100% corn plastic PLA raw material, without any additives, by 100% Biodegradable PLA raw material on the paper,it can be recycled.
The reporter understands, the traditional paper based on the material of composite material is paper, such as LDPE, PET plastic film composite, such as PE, PET plastic is the characteristics of natural degradation, make this kind of packing material can meet the requirements of environmental protection sense completely, and with full PLA biodegradable materials and paper laminating technology development, Solved this worldwide problem once and for all.
PLA coating paper (biodegradable coating paper) is a clean and compostable environmental protection and health product. Polylactic acid (PLA) is a new kind of biodegradable environment-friendly material made from starch derived from renewable plant resources such as maize. Glucose was obtained from starch by saccharification, and then lactic acid with high purity was fermented from glucose and certain strains, and then polylactic acid with certain molecular weight was synthesized by chemical synthesis. It has biodegradable and compostable thermal plastic materials, which take plants as the main raw material source; After extraction, fermentation and polymerization of 100% biodegradable materials, in the compost environment can be completely degraded by natural microorganisms into carbon dioxide and water for plant growth. With good biodegradability, does not pollute the environment, which is very beneficial to protect the environment, is recognized as environmentally friendly materials.
Compared with traditional PE coated paper products, PLA coated paper products can be recycled after use. Its special and diversified recycling and treatment methods of renewable resources greatly reduce the burden of natural resources and the environment, and conform to the green cycle of endless life.
PLA coated paper, PLA can be degraded, high requirements of the manufacturers, are using PLA, PLA price is high, the relative cost performance will be higher, in the long run will be more developable, easier to obtain the welcome of consumers, in response to the latest concept of safety, environmental protection and sustainable development, the future market must belong to PLA coated paper.
