Polymeric compositions that contain a propylene polymer and a propylene-based elastomer. The composition contains 50 wt% to 98 wt% of a propylene polymer and 2 wt% to 50 wt% of a propylene-based elastomer, based on the weight of the composition. The propylene polymer has a melt flow rate (at 230°C) of 10 dg/min to 30 dg/min, and the propylene-based elastomer contains propylene-derived units and 5 wt% to 30 wt% of α-olefin- derived units and has a melting temperature of less than l20°C and a heat of fusion of less than 75 J/g. |
