What are the raw materials of woven bags

The main raw material for foreign production is polyethylene (PE), and the main domestic production is polypropylene (PP), which is a thermoplastic resin prepared by polymerization of ethylene. In industry, it also includes ethylene and small amounts α－ Copolymers of olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low-temperature resistance (the minimum service temperature can reach - 70 ~ - 100 ℃), good chemical stability, can resist the erosion of most acids and bases (not resistant to acids with oxidation properties), is insoluble in general solvents at room temperature, has small water absorption and excellent electrical insulation performance; However, polyethylene is very sensitive to environmental stress (chemical and mechanical action) and has poor heat aging resistance. The properties of polyethylene vary from variety to variety, mainly depending on molecular structure and density.
