Abstract
The invention provides a multiple-layer metallized film comprising a substrate layer of a polymer or copolymer of an alpha-olefin, the molecule of which contains from 2 to 6 carbon atoms, having on at least one surface thereof an adherent layer comprising a random copolymer of ethylene with from 0.5 to 15 wt % of a 3 to 6 carbon alpha-mono-olefin, and a metallic layer on the surface of the adherent layer remote from the substrate. Improved adhesion between the metallized and substrate layers is thereby achieved, and the multi-layer film is suitable for packaging a variety of edible products.
