Abstract
The present disclosure is directed to compositions and methods for improving the cling performance in stretch-cling films. Compositions include: (a) 80.0 to 99.5 wt. % of a propylene-based elastomer, the propylene-based elastomer comprising at least about 60.0 wt. % propylene-derived units and about 5.0 to about 25.0 wt. % ethylene-derived units, based on total weight of the propylene-based elastomer, wherein the propylene-based elastomer has a heat of fusion of less than about 80.0 J/g; and (b) 0.5 to 20.0 wt. % of a polyalphaolefin, wherein the amounts of the propylene-based elastomer, and the polyalphaolefin are based on the weight of the composition. Methods of making such compositions as well as compositions including an ethylene-based polymer and films and methods of making films are also disclosed.
