What kind of film is Pet film? What are the applications of Pet film? Source: Protective film factory direct sales Release time: 2017-12-23 Hits: 2098 As a release film manufacturer, PET film is an undesirable material. What kind of film is the pet film? What is the use of PET film? Let's take a look together today. PET film is also known as high temperature resistant (polyester) PET film. The stability of physical and chemical properties is high, and it is highly transparent and recyclable, so it has a wide range of applications. Specific application areas include magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, optical-grade mirror surface protection, etc. The types of PET film are distinguished by function: PET film (original film) and functional film after PET film secondary processing, such as (PET release film, PET high-gloss film, PET transfer film, PET reflective film, PET antistatic film, PET heat Sealing film, PET heat shrinkable film), etc. Advantages of PET film: ①It has good transparency, light transmittance is not less than 92%, and it is shiny; ②Air tightness and fragrance retention; ③PET film has excellent mechanical properties, manifested in strong toughness, high tensile strength and high impact strength ; And good strength, stable size, suitable for secondary processing; ④PET film also has excellent heat resistance, cold resistance and good chemical resistance and oil resistance. PET film shortcomings: ①not resistant to strong alkali; ②easy to be charged with static electricity, anti-static is an important subject of research and development ③medium moisture resistance, moisture permeability decreases at low temperatures.
