Abstract
The invention concerns films having a cling layer of an elastomeric propylene-based polymer with a low heat of fusion derived from isotactic propylene type crystallinity, as determined by DSC of less than 40 J/g, optionally blended with a crystalline isotactic propylene derived polymer having a heat of fusion over 70 J/g and/or a melting point of at least 120° C. as determined by DSC, and a non-cling layer of a polyolefin. The cling layer may contain other components such as crystalline polypropylene.
