Purpose:

The cushion film, also known as a barrier film or interlayer, serves as a protective layer during the lamination process. It is placed between the substrate (such as paper or cardboard) and the laminating material (usually a film or adhesive).

 Function

Protection: The cushion film provides a barrier that protects the substrate from heat, pressure, and potential damage during the lamination process.

Enhanced Lamination: It helps in achieving uniform lamination by evenly distributing pressure and heat across the surface.

 Release Film:

Purpose: The release film is used to prevent the laminated material from sticking to the rollers or platens of the laminating machine.

 Function

Preventing Adhesion: The release film has a non-stick surface that prevents the laminated material from adhering to the machine's components, ensuring a smooth and clean lamination process.

Easy Handling: It facilitates the easy removal of the laminated material from the machine without any damage.

 Combined Functionality

In some cases, a single film may serve both as a cushion and release layer. These films are designed to offer both protection to the substrate and prevent adhesion to the laminating machine.
