Ordinary PET is a crystalline polymer. After the PET film is stretched and oriented, it will produce a large degree of crystallization. If it is heat sealed, it will produce shrinkage deformation. Therefore, ordinary PET film does not have heat sealing performance.

Polyester film (PET) is a thin film material made of polyethylene terephthalate as raw material, which is extruded into thick sheets and then stretched. Polyester film, environmental protection film, PET film, opalescent film and other printing and packaging consumables are widely used in the glass fiber reinforced plastics industry, building materials industry, printing industry, medicine and health. Polyester film, also known as polyester film, polyester film, photosensitive paper, polyester film, styrene-tin film, cellophane release film.

PET release film is a material commonly used in heat transfer printing. The base material is PET, which is coated with silicone oil, so it is also called silicone oil film. The conventional thickness ranges from 25um to 150um. It can be divided into cold and hot tearing and smooth and matte surface. After anti-static and anti-scratch treatment, the product has good adsorption and adhesion.

The release film refers to the film that can be distinguished on the surface of the film. The release film does not have viscosity or slight viscosity after contacting with specific materials under limited conditions.
