The MOPP film is an extruded film made of polypropylene (PP) . The desired film is produced from the Polypropylene as the starting material for the MOPP film. MOPP films are characterized by extremely high tensile and tear strength and have a low elongation.
MOPP Film MOPP Release Film MOPP Silicone Coated Release Liner refers to the film with separative film on the surface. It is a pleastic film which made of MOPP film as carrier, silicon coated on either one or two-sided releases options.
The film is uniform coated and very smooth and clean without wrinkles/tears/granules/bubbles/pinholes or other defects.
Widely use in polymer waterproof membranes and self-adhesive tapes.

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. |
