Classification and use of PET shrink film Hello everyone, I am the author. Do friends know the shrink film? PET shrink film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, and optical grade mirrors. Surface protection and other fields. With the development of special functional films, new uses of polyester films are also emerging. It can be produced into mobile phone LCD protective film, LCD TV protective film, mobile phone buttons, etc. PET film is a more comprehensive packaging film. It has good transparency and luster; it has good air tightness and fragrance retention; it has medium moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, and its strength and toughness are the best among all thermoplastics. Its tensile strength and impact strength are much higher than those of general films; it has good stiffness and stable dimensions, and is suitable for secondary processing such as printing and paper bags. . PET film also has excellent heat resistance, cold resistance and good chemical resistance and oil resistance. However, it is not resistant to strong alkalis; it is easy to be charged with static electricity, and there is no proper anti-static method. Therefore, attention should be paid when packing powdery articles. Classification of PET film: PET high-gloss film. In addition to the excellent physical and mechanical properties of ordinary polyester film, this film also has excellent gloss PET film properties, such as good transparency, low haze, and high gloss. It is mainly used for high-end vacuum aluminized products. The film is mirror-finished after aluminizing, which has a good packaging decoration effect; it can also be used for laser anti-counterfeiting base films. The high-brightness BOPET film has a large market capacity, high added value and obvious economic benefits.
