1、 PET film is commonly used for packaging beverages and food. It is a new type of polymer material that is transparent, tough, heat-resistant, and environmentally friendly, and is widely used in various fields. The PET film made from it is also known as high-temperature resistant polyester film. This product has excellent physical and chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in fields such as magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, and optical grade mirror surface protection. With the development of special functional films, new uses for polyester films are constantly emerging. It can be produced into mobile phone LCD protective film, LCD TV protective film, mobile phone buttons, etc.  

2、 The characteristics of PET film: PET film is a packaging film with comprehensive performance. It has good transparency, luster, good airtightness, and fragrance retention. Moderate moisture resistance, with a decrease in moisture permeability at low temperatures. PET film has excellent mechanical properties, and its strength and toughness are the best among all thermoplastic plastics. Its tensile strength and impact strength are much higher than ordinary films. In addition, it has the characteristics of good strength and stable size, suitable for secondary processing such as printing and paper bags. PET film also has excellent heat and cold resistance, as well as good chemical and oil resistance. However, it is not resistant to strong alkali and is prone to static electricity. There is currently no appropriate anti-static method, so attention should be paid when packaging powdered items. 3、 Classification of PET film 1. PET high gloss film This film not only has the excellent physical and mechanical properties of ordinary polyester film, but also has excellent optical properties, such as good transparency, low haze, and high glossiness. It is mainly used for high-end vacuum aluminum plated products. After aluminum plating, the film appears mirror like and has a good packaging and decorative effect; It can also be used for laser anti-counterfeiting base film, etc. The high gloss BOPET film market has a large capacity, high added value, and significant economic benefits.
