As a release film manufacturer, polyester film is an indispensable material. What is the PET film? What is the use of PET film? Let's take a look today.
PET film is also known as high temperature resistant (polyester) PET film. High stability of physical and chemical properties, high transparency, recyclable, wide range of applications. Specific application areas include magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging and decoration, screen protection, optical mirror protection, etc.
The types of PET film are distinguished according to their functions: PET film (original film) and functional film after secondary processing of PET film, such as (PET release film, PET high-gloss film, PET transfer film, PET reflective film, PET antistatic film, PET thermal film, etc. Sealing film, PET heat shrinkable film), etc.
Advantages of PET film:
(1) Good transparency, light transmittance not less than 92%, shiny;
(2) Air tightness and fragrance retention;
(3) PET film has excellent mechanical properties, which are characterized by high strength, high toughness, high tensile strength and high impact strength. Suitable for secondary processing.
(4) PET film also has excellent heat resistance, cold resistance, chemical resistance and oil resistance.
Defects of PET film:
(1) Not resistant to strong alkali;
(2) Easy to carry static electricity, anti-static is an important topic of research and development
(3) The moisture resistance is moderate, and the moisture permeability decreases at low temperature.
