Silicone coated release liner refers to the film with separative film on the surface. It 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. |
How to producing release liner:
1. Carrier Film Blowing---3 layers film blowing machine:
2. Silicone Coating(Thermal or UV performance):
| ♦ Used for self-adhesive waterproof membranes and other waterproof materials, adhesive tapes |
| ♦ Used for cables production, packaging materials |
| ♦ Used for cast materials, electronic applications, ceramic capacitors, window materials. printing, electronic, advertisements |

Company History:
Main Fields:
| As a new material field, functional films are also one of the top ten key fields of Made in China 2025, and the awareness in the market is increasing. Nowadays, functional films are not only used in the construction field, special packaging, tape, label, automobile, electronics and other industries, but also in the fields of film filtration, air permeable film, graphene heating film, insulation film, Anti-UV film, biodegradable materials etc.. |
| UPASS, as a leading domestic deep cultivator of polymer functional films, has also entered a stage of rapid development. We believe that UPASS will enter more application fields of polymer films innear future. |
