PE bubble bag company has excellent low temperature resistance (low temperature can reach -70～-100℃), good chemical stability, resistance to most acids alkalis ( resistant to oxidizing acids), insoluble at room temperature Solvent, low water absorption, excellent electrical insulation; but polyethylene is very sensitive to environmental stress (chemical mechanical effects), has poor heat aging resistance. The properties of polyethylene vary species to species, mainly depending on the molecular structure density. Different production methods can be used to obtain products with different densities (0.91～0.96g/cm3). Polyethylene can be processed by general thermoplastic molding methods (see plastic processing).
