ETFE film and FEP film are prepared by melt casting extrusion, film production process is completed in the dust-free workshop, the maximum width of the product up to 1600mm. The release film has excellent chemical resistance, non-sticky surface and high temperature resistance. It can be used as a release film or isolation film for the production of composite materials. The film can be punched and colored according to the needs of customers.
