<p>A multilayer film suitable for cook-in end use includes an outer layer that includes a homo- or co-polymer of propylene and, directly adhered to the out er layer, a layer that includes at least one of: (a) an ethylene/alkyl acrylate copolymer having a high melting point, (b) propylene/.alpha.-olefin copolyme r having a lower propylene mer content than the outer layer and having a high Vicat softening point, and (c) an ethylene/vinyl acetate copolymer with at least 15% vinyl acetate mer content. The film exhibits good seal strength an d good adhesion between the two layers, even in areas where the film is sealed , even after the film is oriented, even when the film is subjected to the elevated temperatures involved in cook-in procedures, and even where the fil m is subjected to, e.g., grease from fatty foods. The film also can include on e or more other layers including, for example, bulk layers, O2-barrier layers, and/or abuse layers.</p> |
