A modifier for forming sub-ambient temperature use containers includes (a) from 10 wt% to 50 wt% of a block composite, a specified block composite, or a crystalline block composite, (b) from 20 wt% to 90 wt% of a first polyolefin copolymer, the first polyolefin copolymer being derived from ethylene and at least one of a C 3 to C 10 alpha-olefin, having a melt index from 0.5 g/10 min to 1500 g/10 min, and having a density from 0.850 g/cm 3 to 0.910 g/cm 3 , and (c) optionally, from 30 wt% to 70 wt% of a second polyolefin copolymer, the second polyolefin copolymer being derived from ethylene and at least one of a C 3 to C 10 alpha-olefin, having a melt index from 100 g/10 min to 2000 g/10 min, and having a density from 0.860 g/cm 3 to 0.900 g/cm 3 . |
