Multiple layer cook-in films are disclosed from which packages such as bags or casings can be made. The films have a first food contact layer with a core layer adhered thereto which includes a blend of a polymeric material having a high molecular weight and a fractional melt index and an ethylene alpha-olefin copolymer. The film further includes an abuse layer which has, at least, a polymeric material having a high molecular weight and a fractional melt index. Improved hold cold seal strength fresh and over time, improved orientation processing and lower shrink temperatures are obtained with the present core layer. The abuse layer and core layer adds to the processability of the material and improves optics. 37
