Abstract:
The present disclosure relates to a method for providing a film. The method may include providing a base layer, wherein the base layer is resistant to one or more of water or oxygen; coextruding a tie layer and a contact layer to provide a coextrusion layer; coating the coextrusion layer to the base layer; allowing the coextrusion layer coated to the base layer to adhere to form the film, wherein the film comprises the tie layer and the contact layer formed as a coextrusion layer coated to the base layer; wherein the tie layer comprises one or more layers, and wherein the tie layer, or the one or more layers of the tie layer, has a loading in the range of 7 to 20 g/m2; wherein the contact layer comprises a cycloolefin copolymer (COC).
