Abstract: The present disclosure provides a flexible container (10). In an embodiment, the flexible container includes a front panel (22), a rear panel (24), a first gusseted side panel (18), and a second gusseted side panel (20). The gusseted side panels adjoin the front panel and the rear panel along peripheral seals (41) to form a chamber. The panels form (i) a top portion, (ii) a body portion, and (iii) a bottom portion. The top portion comprises a neck (27) and a fitment (30) in the neck. The front panel comprises a front handle (82) extending therefrom and the rear panel comprises a rear handle (84) extending therefrom. The front handle and the rear handle are in opposing relation to each other, the front handle and the rear handle extending over the first gusseted side panel.

Abstract: The present disclosure provides for a bicomponent fiber that includes a first region formed of a condensation polymer and a second region formed from a polyethylene blend. The polyethylene blend includes (i) an ethylene-based polymer having a density of 0.920 g/cm3 to 0.970 g/cm3 and a melt index, I2, as determined by ASTM D1238 at 190° C. and 2.16 kg of 0.5 to 150 g/10 minutes; (ii) a maleic anhydride -grafted polyethylene; and (iii) an inorganic Brønsted-Lowry acid having an acid strength pKa value at 25° C. of 1 to 6.5, wherein the polyethylene blend has a 0.03 to 0.5 weight percent of grafted maleic anhydride based on the total weight of the polyethylene blend. The first region is a core region of the bicomponent fiber and the second region is a sheath region of the bicomponent fiber, where the sheath region surrounds the core region.
