The function of the release film: ‌Electronics industry: Used to protect sensitive surfaces like screens and touchscreens, preventing scratches and contamination.

Printing Industry: Used as a temporary carrier for transferring printing patterns or protecting the printing surface.

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

‌Tape and Labels: Backing material for tapes and labels, facilitating easy剥离 during use.‌

The selection of release film requires considerations of factors 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.
