Why does the release film lose silicone oil

Jul 17, 2023 Leave a message

Release film refers to a thin film that can differ in appearance, and it does not have stickiness or slight stickiness when touched with specific materials under limited conditions. Usually, in order to add the release force of plastic film, the plastic film is treated with plasma, coated with fluorine, or coated with silicon release agent on the surface of the film raw material, such as PET, PE, PP, OPP, etc. Various organic pressure sensitive adhesives can exhibit extremely light and stable release force. According to the different required release force of the release film, the viscosity of the isolation product adhesive varies, and the release force should be adjusted accordingly to achieve an extremely light and stable release force during peeling.

PET release film is a commonly used material for heat transfer printing, and the substrate is PET, which is coated with silicone oil and is also called silicone oil film. The conventional thickness ranges from 12um to 100um. There are two types of products: cold and hot tearing and smooth and matte surface. After anti-static and scratch resistant treatment, the product has good adsorption and adhesion.

There are several explanations for why silicone oil falls off the release film:

1. The temperature is too high during the use of release film

2. Improper storage

3. Uneven coating

Release film is a commonly used material in heat transfer printing, and the substrate is PET, which is coated with silicone oil, so it is also called silicone oil film. The conventional thickness ranges from 25um to 150um. There are two types of products: cold and hot tearing and smooth and matte surface. Through anti-static and scratch resistant treatment, the product has excellent adsorption and adhesion.
