Detailed description:

BOPET film, also known as Release Film, is an engineering plastic film with excellent comprehensive properties that uses biaxially oriented technology. The molecular structure of PET plastic is highly symmetrical, with certain crystal orientation, good chemical resistance, and excellent mechanical and electrical properties.

Polyester film is widely used in the production process of fiberglass pipes, storage tanks, and containers, for mold release and surface calendering. After surface coating with silicone oil, demolding is easier and more effective.

The thickness of biaxially oriented polyester film produced by KOPTECH ranges from 13 μm to 100 μm, and it can accept various customized specifications such as roll, corona treatment, silicone oil coating, and transparency.
