HDPE release liner refers to the film with separative film on the surface.
HDPE 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, it does corona treatment to the film and coated with silicone, 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. There are thermal curing and UV curing for silicone coating due to different release force requirements.
Production Process:
1. 3 layers film blowing:
2. Silicone Coating:
1. Used for self-adhesive waterproofing membranes:
2. Used for self-adhesive foam tape:
