Hard to degradable materials
Polyethylene （PE） is a thermoplastic resin made of ethylene by polymerization, to be at high temperatures, there is enough energy before degradation occurs. If the use of polyethylene made of plastic bags will be poor in strength, and heat resistance is not good, there is a certain degree of permeability, sealing strength is not high.
Polyvinyl chloride （PVC） is a polymer made by the polymerization of vinyl chloride monomer （VCM） in the presence of initiators such as peroxides and azo compounds or by the mechanism of free radical polymerization under the action of light and heat. It appears that PVC can only age but not degrade or degrade under the action of light, a process similar to thermal degradation. PVC is mainly used in the construction, electrical and packaging industries.
With the implementation of the “plastic restriction” and “plastic reduction” policies, it is believed that products made of degradable materials will bring more and more surprises to life.
