COATED, ORIENTED POLYMER FILM LAMINATE ABSTRACT OF THE DISCLOSURE A coated, oriented polymer film laminate suitable for packaging applications is provided which comprises: a) an oriented core layer having an upper face and a lower face, the core layer being fabricated from a polypropylene homopolymer; b) an oriented, heat sealable layer applied to the lower face, and optionally, to the upper face, of core layer (a), the heat sealable layer being fabricated from a heat sealable copolymer or blend of copolymers, heat sealable blend of homopolymers and heat sealable blend of at least one copolymer and at least one homopolymer; and c) a coating layer applied to the upper face of core layer (a), or, where heat sealable layer (b) has been applied thereto, to the exposed surface of layer (b), the coating layer being derived from an interpolymer which is obtained from the interpolymerization of from about 0 to 15 parts by weight of an alpha-beta monoethylenically unsaturated carboxylic acid selected from acrylic acid, methacrylic acid and mixtures thereof with from about 85 to about 100 parts by weight of neutral monomer esters.
