PE release film does not have viscidity or slight viscidity contact with specific material under the limited conditions. Normally in order to increase the release force of the film, then do plasma treatment to the film or coated with fluorine, to make it act out the light and stable release force to different organic pressure glue. According to different release film , the release force is different, the viscidity of release product glue is different , to adjust the release force, to make it have the light and stable release force during peeling.
