Disclosed herein are coated articles comprising a substrate having at least one surface, and a coating composition disposed in a substantially continuous layer on at least one surface of the substrate, wherein the coating composition is present in an amount sufficient to increase the oxygen barrier property of the substrate, and the coating composition comprises a polysaccharide derivative. The polysaccharide derivative can comprise a poly alpha-1,3-glucan ether compound, such as a quaternary ammonium alpha-1,3-glucan ether. Also disclosed is packaging comprising the coated article.

A packaging article comprises a heat-shrinkable film having a total free shrink at 85° C. of at least 90%. The film has an inside seal layer, an outside polyester layer, and an inner oxygen barrier layer. A portion of the film contains a crosslinked polymer network. At least one film layer comprises an incompatible polymer blend. The article has tear initiators. The package provides post-shrink, full-length tear from the tear initiators to the opposite edge of the article, for easy product removal. The film has an instrumented impact energy-to-break of at least 0.65 J/mil, and/or an instrumented impact peak load strength of at least 66 Newtons/mil, and/or Truburst strength of at least 8 psi/mil.

A laminated body includes an innermost layer including a sealant formed of a polyethylene-based resin, and a second layer formed of a polyethylene-based resin. The second layer is formed of a biaxially stretched polyethylene-based resin film. The second layer is joined adjacent to the innermost layer via an adhesive layer. At least one member of a packaging bag is formed of the laminated body.

[Object] A laminate is provided which can form packaging bags having a wide range of packaging feasible temperatures and excellent high-speed liquid packaging properties.

[Solution] The laminate includes a sealant layer and an intermediate layer disposed in contact with the sealant layer, the sealant layer including an ethylene/-olefin copolymer satisfying the requirements (x0) to (x3). (x0) The copolymer is a copolymer of ethylene and a C3-C20 -olefin. (x1) The MFR is 1 to 50 g/10 min. (x2) The density is 890 to 910 kg/m.sup.3. (x3) 0.35H (80)/H0.85, and 0.60H (100)/H0.85, wherein H is the total heat of melting observed during DSC, and H (T) is the heat of melting observed during heating from 0 C. to T C.

This invention relates to inner-plies for bulk-bags that surprisingly offer not only high thermal resistance, but also high flex-crack resistance. This invention also relates to such bulk-bags made for packaging of flowable materials, aseptic or otherwise, and the process for improving their flex-crack and thermal resistance. Preferably, the packaging is aseptic. More specifically, the inner-ply of the invention comprises a resin blend comprising the Exceed XP resin; an LDPE resin or an ethylene--olefin copolymer (EAO copolymer); or a blend of said LDPE resin and said EAO copolymer, with flex-crack resistance improved in both machine direction and transverse direction, in conjunction with an improved thermal resistance. Thus, in addition to possessing good flex-crack resistance, the bulk-bags can withstand steam sterilization and/or aseptic packaging conditions.
