Abstract: A metallized film substrate having a core layer comprising a film-forming base polymer, a metal receiving skin layer of an ethylene vinyl alcohol copolymer (EVOH) on a surface of the core layer, the film substrate containing a metal deposit, e.g., aluminum, on the EVOH copolymer surface, and a polymeric low temperature sealable coating comprising a copolymer of about 10 to 35 wt. % of at least one .alpha.,.beta.-ethylenically unsaturated carboxylic acid with about 65 to 90 wt. % of ethylene, an alkyl acrylate or methacrylate, acrylonitrile, or mixtures thereof, on the surface of said metal deposit. For adhesion of the EVOH, the core layer may either (i) be blended with a maleic anhydride modified polyolefin or (ii) have an adhesion-promoting tie layer of a maleic anhydride-modified polyolefin on a surface which is in contact with the EVOH.

Abstract: A multilayer film structure includes:(A) a core layer of high density polyethylene including either a minor proportion of a maleic anhydride modified high density polyethylene blended therein or having(B) a skin layer of maleic anhydride modified polyethylene on one side and(C) on the other side a heat sealable or printable skin layer;this structure having an unbalanced orientation such that the degree of transverse direction orientation produces a visible rippled and striated appearance, with the ripples and striations being parallel to the transverse direction of orientation. This structure can also have a layer of ethylene vinyl alcohol copolymer on the maleic anhydride modified polyethylene-containing layer. The maleic anhydride modified HDPE or the EVOH can be metallized and the final structure laminated to a separate film structure.
