[0002] PE is the abbreviation of polyethylene, which is a thermoplastic resin obtained by polymerization of ethylene. Industrially, it also includes copolymers of ethylene and a small amount of α-olefins; it is a transparent plastic bag that can be used for packaging clothing, luggage, electronic products, etc. It has excellent low-temperature resistance (the lowest use temperature can reach -70 to -100 °C), good chemical stability, and can resist the erosion of most acids and alkalis (except acids with oxidation properties). It is insoluble in general solvents at room temperature, has low water absorption, and excellent electrical insulation performance; however, polyethylene is very sensitive to environmental stress (chemical and mechanical effects) and has poor heat aging resistance. The properties of polyethylene vary depending on the variety, mainly depending on the molecular structure and density. Products with different densities (0.91 - 0.96 g / cm3) can be obtained by using different production methods, and polyethylene can be processed by the forming methods of general thermoplastic plastics.
