High quality plastic pellet raw material PET resin
Polyethylene terephthalate
PET resin is the most common thermoplastic polymer resin in the polyester family and is used inbottle packaging containers; can be used to manufacture food and beverage packaging bottles. Bottle-grade polyester chips have uniform crystal structure and narrow molecular mass distribution; non-toxic, odorless, glass-like transparency and luster; good impact toughness and high strength; low gas permeability (that is, good barrier properties), can Extend the shelf life of beverages; simple processing, small dimensional changes or small creep under load.
