BIAXIALLY ORIENTED POLYESTER FILM FOR MOLDING PROCESS
摘要
Described are smooth biaxially oriented films and methods of making smooth biaxially oriented films for molding processes. The films may include an outer film layer A, and an outer film layer B that includes particles. Layer A has a SRa roughness of from 1 nm to 5 nm and a SRz roughness of from 10 nm to 100 nm. Layer B has a SRa roughness of from 5 nm to 50 nm and a SRz roughness of from 10 nm to 200 nm. The SRa and SRz of layer B is larger than the SRa and SRz of layer A.
