Customized Transparent PET Polyester Film BOPET Material For Wire / Cable Belt
Transparent PET polyester film , customized for wire and cable belt
Characteristic
PET polyester film is called PET film for short. It is characterized by high temperature resistance, good printing, easy processing, good voltage resistance and insulation. It is a thin film material made of polyethylene terephthalate as raw material, which is extruded into thick sheets and then drawn in two directions.
