摘要: This disclosure relates to a multilayer film and a process making such a film. The multilayer film of this disclosure includes (a) a metallizable skin layer having at least one of a grafted isotactic polypropylene, a grafted minirandom copolymer of isotactic polypropylene, a grafted propylene-based elastomer, or any combinations thereof; and (b) a metal layer deposited on the metallizable skin layer, wherein the isotacticity of said isotactic polypropylene is 85% or greater; the ethylene concentration of said minirandom copolymer is 1.0 wt. % or lower; the propylene concentration of said propylene-based elastomer is 89 wt. % or greater; and, wherein the graft monomer includes at least one of ethylenically unsaturated carboxylic acids, ethylenically unsaturated carboxylic acid derivatives and any combination thereof.
