What are the raw materials of woven sacks
The main raw material for foreign production is polyethylene (PE), while domestic production is mainly polypropylene (PP), which is a thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is odorless, non-toxic, feels like wax, has excellent low-temperature resistance (the minimum use temperature can reach -70～-100℃), has good chemical stability, and can withstand most acids and alkalis (not resistant to oxidizing properties) Acid), insoluble in general solvents at room temperature, low water absorption, and excellent electrical insulation properties; but polyethylene is very sensitive to environmental stress (chemical and mechanical effects), and has poor heat aging resistance. The properties of polyethylene vary from species to species, mainly depending on the molecular structure and density.
