China Polyester Based Film for Optical Applications Manufacturer and Supplier

Polyester Based Film for Optical Applications

Optical PET based films are widely used in applications like display, 5G communication, environmental protection and energy saving as a carrier film. With specific co-extrusion of ABA or ABC structure and wide range of thicknesses, Dongfang endeavors its efforts to meet individual application needs. The films we offered are mainly applied to areas like OCA, POL, MLCC, BEF, diffusion film, window film, releasing and protection film. Simultaneously, we undertake national industrial key project of optical polyester base film for TFT polarizer with annual production capability of 100 million sqms to contribute process of localization.
