Our polarizer protective film and release film base film are made of high-quality PET base film, which is specially designed for optical applications. The film has excellent transparency and optical properties, can effectively filter unnecessary light, and improve the use effect of polarizer. At the same time, polyester material has excellent temperature resistance and chemical stability, ensuring that the film maintains stable performance in various environments and prolongs its service life.

The polarizer protective film we produce can effectively prevent scratches and pollution, protect the surface of the polarizer, and ensure its long-term clarity and efficiency. The release film has good peeling performance, which is convenient for subsequent processing and improves production efficiency.
