ABSTRACT OF THE DISCLOSURE This invention pertains to the use of polymer blends in making multiple layer films. In some layers, the elastomer or ethylene-based copolymer is blended with polypropylene, and in some layers, with polyethylene. Typical films have two to five layers. In multilayer films, at least one layer of a blend of polyethylene, preferably high density polyethylene, with elastomer and/or ethylene-based copolymers. Another layer is polypropylene blended with elastomers and/or- ethylene-based copolymers. The films may have as few as two layers, one each having polypropylene and polyethylene, preferably high density polyethylene. Additional layers may be added to the two or three layer films taught herein, for variety of purposes.
