‌Composite Materials: In the lamination process of composite materials, release film is used to isolate the individual layers and prevent adhesion.

‌Tape and Labels: The backing material for tape and labels, facilitating easy peeling during use.‌

The selection of release film requires considerations such as thickness, release force, and temperature resistance. Common thickness ranges from 25 micrometers to 200 micrometers, with release force adjusted according to specific application needs, typically between 5-50g/25mm.
