The function of the release film: In the electronics industry, it is used to protect sensitive surfaces such as screens and touch screens, preventing scratches and contamination.

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

‌Composite Materials: In the lamination process of composite materials, a release film is used to separate the layers and prevent sticking.

‌Tape and Labels: Backing material for tape and labels, facilitating peeling 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.
