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.

Abstract: The present disclosure provides a flexible pouch. In an embodiment, the flexible pouch includes a first layer structure and a second layer structure. Each layer structure includes (i) an inner liner and (ii) an outer sheath. The first layer structure is superimposed on the second layer structure such that the inner liners oppose each other. The first layer structure superimposed upon the second layer structure defines a common peripheral edge. Each inner liner is composed of a flexible film of a polymeric material. Each outer sheath is composed of a post-consumer recycle (PCR) polymer material. The PCR polymer material has a GI200 value greater than 50. The flexible pouch includes a peripheral seal. The peripheral seal extends along at least a portion of the common peripheral edge. The peripheral seal seals the first layer structure to the second layer structure.
