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.
