Release film refers to a film with a distinguishable film surface. The release film does not have or is slightly sticky after contact 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 silicone release agent on the surface of the film material. Such as PET, PE, OPP, etc. Let it show extremely light and stable release force for various organic pressure-sensitive adhesives (such as hot melt adhesive, acrylic adhesive and rubber-based pressure sensitive adhesive).

According to the different required release film release forces, the viscosity of the isolation product adhesive is different. The release force is adjusted accordingly to achieve a very light and stable release force during peeling

PET release film is also called PET silicone oil film. It is to apply a layer of silicone oil on the surface of the PET film. It can reduce the adhesion on the surface of the PET film and achieve a release effect. We are a PET release film supplier in China.

PET release film can be divided into single-sided release film and double-sided release film. According to the release force, it can be divided into light release film, medium release film and heavy release film.

Commonly used thicknesses are: 0.012mm, 0.019mm, 0.025mm, 0.038mm, 0.05mm, 0.075mm, 0.1mm, 0.125mm, 0.188mm. PET release film manufacturers are equipped with large slitting and slicing machines, Divide and slice according to your specifications
