Abstract
A fluoropolymer coated film comprising polymeric substrate film and fluoropolymer coating on the polymeric substrate film. The fluoropolymer coating comprises fluoropolymer selected from homopolymers and copolymers of vinyl fluoride and homopolymers and copolymers of vinylidene fluoride polymer blended with compatible adhesive polymer comprising functional groups selected from carboxylic acid, sulfonic acid, aziridine, anhydride, amine, isocyanate, melamine, epoxy, hydroxy, anhydride and mixtures thereof. The polymeric substrate film comprises functional groups on its surface that interact with the compatible adhesive polymer to promote bonding of the fluoropolymer coating to the substrate film.
