What are the uses of PET film?

PET film is a kind of transparent and glossy film, which has good optical and weather resistance, good wear and friction resistance, dimensional stability and electrical insulation. Using the above-mentioned high-quality characteristics, PET can be used in many fields, for example, it can be used as a high-grade packaging material for food, medicine, textiles, precision instruments and electrical components; Or for; Bottle packaging of various bottled drinks, edible oils, etc. ; It can also be used for making automobile exterior decoration parts or for microwave baking trays, outdoor billboards or models. Through the continuous upgrading of technology, PET can be applied in more fields. Polyester film is extruded from polyethylene terephthalate? Thick sheet, and then made into film material by biaxial stretching. It is a colorless, transparent and glossy film with excellent mechanical properties, high rigidity, high hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, oil resistance, air tightness and fragrance retention. It is one of the commonly used barrier composite membrane substrates. However, the price of polyester film is relatively high, and the thickness is generally 12 pm. It is often used as an outer layer material for cooking and packaging, and has good printability.
