A gas barrier layer-forming composition contains a solid content containing a polyurethane resin, a water-soluble polymer and a curing agent. The polyurethane resin contains a reaction product of an acid group-containing polyurethane resin having an acid group and a polyamine compound having an amino group. The polyurethane resin content, the water-soluble polymer content, and an inorganic layered mineral content in the solid content are 45 mass % or more and 75 mass % or less, 20 mass % or more and 35 mass % or less, and less than 2 mass %, respectively.

The present invention is a self-standing spout-equipped packaging bag (1), including a bag body (10) that stores contents, and a spout (12) that is attached to an upper portion of the bag body (10). The bag body (10) includes a tubular barrel portion (20), and a bottom portion (22) which is attached to block an opening end of a lower part of the barrel portion (20). The spout (12) includes a tubular nozzle portion (14), and a flange portion (16) which projects from an outer surface of the nozzle portion (14). An upper end part (21) of the tubular barrel portion (20) over an entire circumference is liquid-tightly adhered to an upper surface (16e) of the flange portion (16) in a state of following a shape of the flange portion (16) in plan view to be in the same shape.

Multilayer Films have a first skin layer that is prepared from a high density polyethylene and a second skin layer (also referred to as the sealant layer) that is prepared from a linear low density polyethylene (LLDPE) having a density of from 0.90 to 0.92 g/cc and a Dilution Index, Yd, of greater than 0°. Seals can be prepared by placing two pieces of this film against each other such that the sealant layers are in contact with each other, then applying heat to at least one high density skin layer such that heat is transmitted/conducted through the multilayer film in a sufficient amount to melt the sealant layer and form a seal. The use of LLDPE having a Dilution Index of greater than 0° has been found to improve the sealing performance of multilayer films in comparison to multilayer films where the sealant layer is a conventional LLDPE having a Dilution Index of less than 0°.

Embodiments of multilayer films and laminate structures for flexible packaging comprise a multilayer polyolefin film comprising at least 3 layers. The multilayer polyolefin film comprises a first surface layer comprising: a first composition comprising at least one ethylene based polymer, wherein the first composition comprises a Molecular Weighted Comonomer Distribution Index (MWCDI) value greater than 0.9, and a melt index ratio (I.sub.10/I.sub.2) that meets the following equation: I.sub.10/I.sub.2≥7.0−1.2×log (I.sub.2). The first surface layer also comprises a second composition comprising an ethylene based polymer having a density from 0.890 to 0.925 g/cc and a melt index (I.sub.2) from 0.2 to 2.0 g/10 min. The multilayer polyolefin film also comprises a first intermediate layer comprising the first composition.

An elongated bag for use as a ready-to-use grow bag. The bag is manufactured as an elongated plastic body with a sealed bottom and a sealable top. The bag includes one or more gussets defined by folds in the bag and a score line for a tear strip in an area sufficiently below the top and above the fill material to allow the bag to lie flat for transportation and deploy into a cylinder for planting. The bag includes drain holes near the bottom of the bag and microperforations along the bag for respiration.

The present disclosure provides a flexible container. In an embodiment, the flexible container includes (A) a front panel, a rear panel, a first gusseted side panel, and a second gusseted side panel. The gusseted side panels adjoin the front panel and the rear panel along peripheral seals to form a chamber. Each peripheral seal has (i) a body seal inner edge (BSIE) with opposing ends, (ii) a top tapered seal inner edge (t-TSIE) extending from a top end of each BSIE, (iii) a neck seal inner edge (NSIE) extending from a top end of each t-TSIE, (iv) a neck arc extending between each NSIE and t-TSIE, and (v) a plane (N) extending through each neck arc. Each NSIE forms a neck angle with the plane (N), and the neck angle is from 45° to less than 90°.

The present disclosure is directed to a flexible pouch. In an embodiment, a flexible pouch is provided and includes opposing flexible laminates sealed along a common peripheral edge to form a storage compartment. Each flexible laminate has at least three layers comprising (A) a seal layer, (B) an outermost layer, and (C) an adhesive layer between the seal layer and the outer layer. The adhesive layer comprises a solvent-free polyurethane adhesive composition. An alcoholic beverage is present in the storage compartment. The flexible pouch has a solvent residue less than 1.0 mg/m.sup.2, and a bond strength greater than 200 gm/15 mm after a 60-day liquor resistance test.

A self-standing packaging bag for use in a microwave oven. The packaging bag is made of a flexible film formed into a bag shape, the packaging bag includes a bottom surface portion and a peripheral surface portion provided to rise from the bottom surface portion, the peripheral surface portion includes a front surface portion and a back surface portion facing each other and includes an opening that opens upward, the peripheral surface portion includes an openable member configured to open and close the opening, and an opening portion for opening the packaging bag, the opening portion is provided closer to the bottom surface portion than the openable member, a container-shaped main body portion obtained by tearing the peripheral surface portion in a circumferential direction at the opening portion and removing a tear-off portion above the opening portion is usable as a dish when eating contents in the packaging bag.
