Abstract
A multilayer film has a core layer, such as a biaxially oriented polypropylene layer, and an adhesion promoting layer formed from a graft copolymer of syndiotactic polypropylene and a monomer, such as maleic anhydride, which has hydrophilic functionality. The adhesion promoting layer may be metallized to provide a barrier to oxygen and water vapor. The adhesion promoting layer may also render the surface of the film more receptive to printing inks, laminating adhesives, primeness overcoats and the like.
