ABSTRACT:
The present invention is a multilayered coextruded film and process of coextruding. The coextruded film comprises at least one thermoplastic fluoropolymer layer and at least one thermoplastic polymeric layer adjacent to the thermoplastic fluoropolymer layer. There is preferably a coextruded adhesive layer between each thermoplastic fluoropolymer layer and each thermoplastic polymeric layer. The coextruded film can be oriented in at least one direction and/or embossed without delamination, fibrillating, or splitting.
