Abstract

A multilayer film including an outer layer that includes a homo- or interpolymer of propylene and, directly adhered to the outer layer, a layer that includes a homogeneous ethylene/.alpha.-olefin interpolymer having a density of no more than about 0.91 g/cm3 exhibits good seal strength and 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 film is subjected to, e.g., grease from fatty foods. The film also can include one or more, for example, bulk layers, O2-barrier layers, and/or abuse layers.
