ABSTRACT:
A polymeric film comprises a substrate layer of polymeric material and a coating layer formed from a composition comprising a layer mineral and a cross-linking agent. The coating layer comprises greater than 10% and less than 90% by weight of the layer of the layer mineral and greater than 10% and less than 90% by weight of the layer of a resin derived from the cross-linking agent. The coating layer preferably additionally comprises a copolymer of ethylene with a vinyl monomer. The polymeric film can have oxygen barrier properties, and the layer mineral coating layer exhibits improved adhesion to the polymeric substrate. The polymeric film is particularly suitable for use as a packaging film.
