Films or sheets are fabricated from blends of an ethylenic homopolymer or copolymer, a butene-1 copolymer, and a propylene homopolymer or copolymer which result in good peel characteristics, and wherein such films or sheets will bond to a polypropylene substrate in a laminar structure by extrusion lamination without the need for an adhesive.
