Good low temperature resistance, PE vacuum bag the lowest temperature can reach 70 ~ 100 degrees.
Polyethylene chemistry stability is good, can bear most of the acid and alkali erosion, room temperature does not dissolve in solvents, water quantity is small, electric insulation performance is good, but the polyethylene heat resistance is poor.
Polypropylene with high impact, strong mechanical properties, resistance to all kinds of organic solvent and acid and alkali corrosion.
