1. A fitment comprising:
a top portion, a base, and a channel extending through the top portion and the base for passage of a flowable material;
the fitment composed of a polymeric composition that is a two-component blend of:
(i) from 70 to 90 weight percent of a high density polyethylene (HDPE) having a density from 0.940 g/cc to 0.970 g/cc, a melt temperature, Tm, greater than 125° C., and a melt index from 1 g/10 min to 50 g/10 min; and
(ii) from 30 to 10 weight percent of an olefin-based elastomer having a density from 0.860 g/cc to 0.905 g/cc, a melt index from 0.2 g/10 min to 50 g/10 min, and a Tm less than 125° C.;
(iii) the two-component blend having
(a) a density from 0.930 g/cc to 0.945 g/cc, and
(b) a melt temperature from 127° C. to 131° C.;
the base comprising a pair of opposing sidewalls defining a canoe-shape when the fitment is viewed from a bottom plan view;
the sidewalls extending around opposite sides of the channel and join together to form opposing ends; and
each end is parallel to the channel.
