- Brand Name:-
Hengli's polyester film brand is distinguished by its exceptional properties, including high tensile strength, elastic modulus, impact strength, and bending resistance. The film also exhibits
remarkable characteristics such as high surface gloss and transparency, heat resistance up to 210°C, good thermal stability, non-toxicity, tastelessness, excellent oxygen permeability, moisture
resistance, and chemical resistance. It possesses outstanding optical and electrical insulation properties, featuring high power frequency electrical strength, low dielectric loss, and
significant resistivity.
Moreover, the film's physical attributes can be enhanced through specialized treatments, addressing aspects like surface smoothness, antistatic properties, dimensional stability, and surface
adhesion. Recognized as a green material, BOPET film stands out for its superior overall performance and recyclability.
