Summary:A composition comprising (A) from 40 wt % to 75 wt % of a propylene component including at least one propylene based polymer having a propylene content of at least 50.0 wt %, based on the total weight of the propylene based polymer, and a melt flow rate from 1.0 g/10 min to 100.0 g/10 min (ASTM D-1238 at 230° C., 2.16 kg); (B) from 1 wt % to 40 wt % of an olefin block copolymer; and (C) from 1 wt % to 20 wt % of an ethylene component including at least one ethylene based polymer having an ethylene content of at least 50.0 wt %, based on the total weight of the ethylene based polymer, and a melt index from 0.1 g/10 min to 50.0 g/10 min (ASTM D-1238 at 190° C., 2.16 kg).
