Why does the release film lose silicone oil?

The release film refers to a film that can be distinguished on the surface of the film. The release film does not have stickiness or slight stickiness after touching it with a specific material under limited conditions. Usually, in order to increase the release force of the plastic film, the plastic film will be plasma treated, or coated with fluorine, or coated with a silicon release agent on the surface of the film raw material, such as PET, PE, PP, OPP, etc. For a variety of different organic pressure-sensitive adhesives can show extremely light and stable release force. Depending on the release force of the release film required, the viscosity of the isolation product adhesive is different, and the release force is adjusted accordingly to achieve a very light and stable release force during peeling.
