<p>The invention provides a film comprising at least one layer formed from a composition comprising a propylene-based polymer and a saturated compound, selected from the group consisting of aliphatic amides, hydrocarbon waxes, hydrocarbon oils, fluorinated hydrocarbons, siloxanes, and combinations thereof; and wherein the propylene-based polymer has less than 0.01 mole percent total unsaturations, as determined by 1H NMR. The invention also provides a composition comprising a propylene-based polymer and a saturated compound, selected from the group consisting of aliphatic amides, hydrocarbon waxes, hydrocarbon oils, fluorinated hydrocarbons, siloxanes, and combinations thereof, and wherein the propylene-based polymer comprises (A) at least 60 weight percent (wt%) units derived from propylene, and (B) from 1 to 40 wt% units derived from ethylene, and wherein the propylene polymer is characterized by at least one of the following properties: (1) a g' ratio of less than one, measured at polymer number average molecular weight (Mn), (2) a relative compositional drift of less than 50%, and (3) propylene chain segments having a chain isotacticity triad index of at least 70 mole percent. The invention also provides a film comprising at least one layer formed from a composition comprising a ethylene-based polymer and a saturated compound, selected from the group consisting of aliphatic amides, hydrocarbon waxes, hydrocarbon oils, fluorinated hydrocarbons, siloxanes, and combinations thereof, and wherein the ethylene-based polymer has a density greater than, or equal to, 0.930 g/cc.</p> |
