Abstract:
A metallized multilayer film structure comprising:(a) a core layer comprising isotactic propylene homopolymer, the core layer having a first side and a second side; (b) a metal receiving skin layer on the first side of the core layer, wherein the metal receiving skin layer comprises a film-forming polyolefin selected from the group consisting of high density polyethylene (HDPE), ethylene-propylene random copolymer, propylene-butylene copolymer, ethylene-propylene-butylene terpolymer, propylene homopolymer, and blends thereof; (c) a metal layer deposited on the surface of the metal receiving skin layer opposite the core layer; (d) a topcoat layer on the surface of the metal layer opposite the metal receiving skin layer, the topcoat layer comprising a coating and a coloring agent, wherein: the coating is selected from the group consisting of an ethylene acrylic acid copolymer (EAA) coating, an ethylene methacrylic acid copolymer (EMA) coating, an acrylonitrile coating, a urethane coating, an epoxy coating, and blends thereof, and the coloring agent is selected from the group consisting of phthalocyanine, azo, condensed azo, azo lake, anthraquinone, perylene/perinone, indigo/thioindigo, isoindolinone, azomethineazo, dioxazine, quinacridone, aniline black, triphenylmethane, carbon black, titanium oxide, iron oxide, iron hydroxide, chrome oxide, calcinated spinel, chromic acid, chrome vermilion, iron blue, aluminum powder and bronze powder; and (e) a polymer skin layer on the second side of the core layer, the polymer skin layer comprising a film-forming polyolefin selected from the group consisting of ethylene-propylene random copolymer, ethylene-propylene block copolymer, ethylene-propylene-butylene terpolymer, and propylene-butylene copolymer.
