Abstract: A single-use bag includes a collapsible a body having a first end and an opposing second end bounding a compartment. The collapsible body comprises at least one flexible sheet having an interior surface and an exterior surface; wherein the interior surface layer comprises low density polyethylene having a melt index from 0.9 to 2.0 g/10 min with a weight average molecular weight (Mw) greater than 200,000 Da, and an Mz greater than 1,500,000 Da. Optionally, the flexible sheet comprises an oriented film as an additional layer on the exterior surface. The single-use bag is useful in biological processing, including use in a disposable cell culture bioreactor.

Abstract: An article such as a film or sheet comprises a heat-sealable polyester composition having an amorphous processing window ranging from a Tg in the range of about 40 to about 70° C., to a Tcg in the range of about 70 to about 150° C. The composition comprises poly(trimethylene furandicarboxylate) homopolymer or copolymer, or a blend of poly(trimethylene furandicarboxylate) homopolymer or copolymer with other polymers such as poly(alkylene furandicarboxylate) homopolymer or copolymer or poly(alkylene terephthalate) homopolymer or copolymer. The resulting composition is heat-sealable at low temperatures, and exhibits superior barrier properties compared to poly(ethylene terephthalate).

Abstract: A polymeric film, multiple-compartment, pouch having an internal frangible seal for confining a fluid and related beverage container with a re-closable fitment for storing and delivering two different flavored liquids or the like. The frangible seal of the clear plastic pouch will burst when sustained squeezed thus allowing the flavors to swirl and mix within the pouch.
