ZunyiPolyester film

　　Polyester film (PET) is a thin film material produced by extruding a thick sheet from polyethylene terephthalate and then stretching it. Polyester film is an environmentally friendly consumable used in printing and packaging, widely applied in the fiberglass industry, building materials sector, printing industry, and the pharmaceutical and healthcare fields. It is also known as polyester film, clear film, dacron film, photosensitive paper, polyethylene terephthalate film, benzotin film, glassine paper, or release film.
　　Polyester film is a high‑performance polymer film that has increasingly won favor among consumers thanks to its excellent overall properties. However, China’s production capacity and technological level still fall short of market demand, leaving the country reliant on imports for certain applications.
