More and more customers in the market choose vacuum packaging bags as packaging items, among which vacuum bags PE and PP vacuum bags are an important part of vacuum bag products, which provide great convenience for people’s daily life and industrial production. Today we come See what they have in common. What’s the difference? Different uses: Polyethylene (PE) is widely used in the manufacture of vacuum bags, plastic films, milk barrels and other products. Polypropylene (nylon) is widely used in industry, and the third. The most rare polymer materials are used to manufacture various adhesives Adhesive tapes have made great contributions to the food, beverage and other flexible packaging industries. The chemical structure is different: polyethylene is polyethylene, first of all. A simple polymer containing O one repeating CH2 unit, which is formed by the addition of ethylene. pp refers to a semi-crystalline thermoplastic. Its characteristics are different: polyethylene is odorless, non-toxic, feels like wax, second. Good low temperature resistance, the lowest temperature of PE vacuum bag can reach 70~100 degrees. Polyethylene has good chemical stability and can withstand large Partial acid and alkali corrosion, insoluble in common solvents at room temperature, small water absorption, good electrical insulation performance, but poor heat resistance of polyethylene. Polypropylene has high impact resistance, strong mechanical properties, resistance to various organic solvents and acid and alkali corrosion.
