Zusammenfassung:	Coextruded or laminated multilayer films are provided having at least one layer of a fluoropolymer homopolymer or copolymer, a layer of a high-pressure, low-density polyethylene and an intermediate adhesive tie layer. Such barrier films substantially reduce the leaching of contaminants barrier film into a packaged product, or are completely leach resistant.
