Polyethylene plastic is a kind of polymer compound, polyethylene plastic products with synthetic resin as the main raw material, add appropriate amount of plasticizers, stabilizers, antioxidants and other additives, under certain plasticizing conditions processing. At present, the food containers, packaging materials and thermoplastic plastics allowed in the manufacture of food tools and equipment in China include polyethylene, polypropylene, polyvinyl chloride, vinylidene chloride, polycarbonate, polyethylene terephthalate, nylon, unsaturated polyester resin, acrylonitrile-styrene copolymer resin, reenenitrile-styrene copolymer resin, acrylonitrile-butadiene-styrene copolymer resin, etc.; Thermosetting plastics include melamine, formaldehyde resin, etc.

According to the pressure during polymerization, polyethylene plastics are divided into high-pressure polyethylene or low-density polyethylene (LDPE) and low-pressure polyethylene or high-density polyethylene (HDPE). High-pressure polyethylene is mainly used in the manufacture of food plastic bags, plastic wrap, etc.; Low-pressure polyethylene is mainly used in the manufacture of food plastic containers, tubes, cutting boards, etc. Polypropylene plastic film can be longitudinally and transversely stretched to change its mechanical properties, strength and transparency increase, according to the stretching direction of polypropylene plastic film is mainly used in the manufacture of food plastic bags, especially composite plastic bags; Polypropylene can also be processed into food containers that are resistant to both low and high temperatures, such as crispers and microwave ovens.
