Q: What is the material of detergent bag?: Polypropylene English Name: Polypropylene, abbreviation: PP, commonly known as: 100 fold glue. Polypropylene is a representative of poly - alpha olefins, a thermoplastic resin made by the polymerization of propylene. Its monomer is propylene CH2=CH - CH3. According to the initiator and polymerization process, polypropylene can be divided into isotactic polypropylene and random polypropylene and syndiotactic polypropylene three configurations. Isotactic polypropylene is easy to form crystalline, high crystallinity reached more than 95%, the molecular weight of 8-15 million, giving it a good thermal and solvent resistance; atactic polypropylene at room temperature is white wax microstrip viscous a non crystalline, low molecular weight, in 3000-10000, the lack of irregular structure cohesion, application.

PVC film can also be used for stretch or heat shrink packaging, used for packaging mattresses, cloth, toys and industrial goods.
