Polyethylene (PE) Polyethylene is a polymer of ethylene and a thermoplastic plastic. Polyethylene is a kind of milky waxy solid
like small cubes, lighter than water, softer water resistance, resistance to low temperature, odorless, non-toxic; Poor heat
resistance, poor film air tightness, very sensitive to ultraviolet light, easy oxidation, aging and degradation, thermal shrinkage
change is relatively large, poor printing performance dyeing is more difficult to color. According to its density, it can be
divided into high density polyethylene (HDPE), medium density polyethylene (MDPE) and low density polyethylene (LDPE). If the polyvinyl chloride resin to add some plasticizer or dyeing agent, stabilizer and other chemical additives, to calendering molding method PVC cosmetic packaging bags.
