Abstract
The present disclosure provides a fitment. In an embodiment, a fitment is provided and includes a top portion, a base, and a channel extending through the top portion and the base for passage of a flowable material. The fitment is composed of a polymeric composition. The polymeric composition includes (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.
Claims16
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.
A flexible container comprising:
- a first multilayer film and a second multilayer film, each multilayer film comprising a seal layer, the multilayer films arranged such that the seal layers oppose each other and the second multilayer film is superimposed on the first multilayer film;
- a fitment sandwiched between the first multilayer film and the second multilayer film, the fitment comprising of a top portion, a base, and a channel extending through the top portion and the base, the fitment composed of a polymeric composition that is a two-component blend of
- (i) from 70 weight percent 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 10 weight percent to 30 weight percent of an olefin-based elastomer having a density from 0.860 g/cc to 0.905 g/cc 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;
- each end is parallel to the channel;
- and
- the base is sealed to the first multilayer film and the second multilayer film.
