Polyester is a category of polymers that contain the ester functional group in their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in the cutting of plant cuticles, as well as synthetics through step-growth polymerization such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. The material is used extensively in clothing. This Have excellent mechanical properties, dielectric strength, and dimensional stability, as well as low water absorption, and good resistance to most chemicals. These general purpose films are often used for industrial laminates and electric motor and cable insulation. Polyester films that have enhanced adhesion to inks and adhesives. They are used for printing and solvent-based coating applications. These films are often specified for printed labels, masking applications, engineering drawings, and face shields. Two side slip treated polyester film with high clarity and gloss, good dimensional stability, and excellent handling characteristics. Polyester Film is used in printing process and after printing it is laminated with other material and then it is used to make pouches. It is the base or outer protective layer of most thermal laminating film. It does not melt during the thermal laminating process. It is also the base layer of many other films. It is widely used in different industry verticals of this world of trade. These are the base or outer protective layer of most of the thermal laminating films and many other films. The Polyester Films we offer do not melt during the thermal laminating process.
