A multilayer film for ostomy and bowel management applications includes a barrier layer comprising at least about 90% wt. nylon 6/69. The multilayer film provides excellent mechanical and odor barrier properties, and softness and quietness desired in ostomy and bowel management applications.

The present invention is related to a retortable package comprising a flexible multilayer substrate comprising a reverse-printed layer, said reverse-printed layer comprising one or more crosslinked ink layer(s), and to a method for producing said multilayer laminate.

The invention relates to a method for producing a multilayer structure comprising an organic barrier layer, adhesive layer and substrate, comprising the following steps (a) providing a carrier film, (b) wherein a major part of the surface of the carrier film is provided with a release agent chosen from (i) an organic release layer, which organic release layer has the capacity to effect a releasable bond from the surface of the carrier film and a non-releasable bond with the surface of an organic barrier layer to be applied on the release layer and/or (ii) a metal layer on the carrier film which adheres stronger to the carrier film than to the organic barrier layer, (c) providing an organic barrier layer on the release agent, (d) providing an adhesive layer on the organic barrier layer, and bonding the organic barrier layer with said adhesive to a substrate, and (e) stripping said carrier film from the multilayer structure.

Provided is a resin composition comprising an ethylene-vinyl alcohol copolymer (A), a hydrate-forming metal salt (B), and a polyamide-based resin (C) that inhibits elution of a resin composition layer during hot water sterilization treatment of a multilayered structure including the resin composition layer, while suppressing odor during melt molding of the resin composition. An aromatic polyamide (C1) and an aliphatic polyamide (C2) are used for the polyamide-based resin (C) at a proportion of (C1)/(C2)=55/45-99/1.

The present patent application relates to a method of manufacturing a multilayered composite film comprising a step of co-extruding at least three layers (a), (b) and (c), of which the layer (a) forms an outward surface of the composite film; the layer (c) forms a surface of the composite film facing or coming in contact with a good to be packaged; and the layer (b) is disposed between the layer (a) and the layer (c). Further, the method includes a step of biaxial orientation of the composite film thus co-extruded. Therein, the layer (a) contains or consists of a thermoplastic resin. The layer (b) contains or consists of a polyvinylidene chloride (PVdC) resin. The layer (c) contains or consists of a resin, preferably sealable, in particular heat-sealable resin. Therein, any crosslinking of the composite film by means of radioactive radiation, in particular by means of beta, gamma, X-ray and/or electron irradiation, is omitted during the manufacturing of the composite film and/or thereafter.

This invention relates to a process for reducing or eliminating organoleptic degradation in organoleptically sensitive foods packaged in flexible packaging, and packaged products thereof. This invention also relates to organoleptic flexible packaging made from polymeric films comprising oxidation-stable and non-migratory polysiloxane as slip additive. The oxidative-stability and non-migratory nature of the polysiloxane slip additive provides an organoleptic flexible packaging that is non-interactive with and inert to the organoleptically sensitive food packaged within, specifically: (1) coffee; (2) beer; (3) water; and (4) wine.

The present disclosure provides a film. In an embodiment, a multilayer film is provided and includes (A) a seal layer, (B) a barrier layer, and (C) an odor control layer. The odor control layer includes an odor control composition containing (A) from 85 wt % to 99.5 wt % of an olefin-based polymer and (B) from 15 wt % to 0.5 wt % of an odor suppressant. The odor suppressant includes a blend of: (i) an ionomer, (ii) particles of zinc oxide, and (iii) particles of copper oxide. The composition has a methyl mercaptan odor suppression value of greater than 45% as measured in accordance with ASTM D5504-12.

A laminated product for flexible packaging is provided, in which at least a paper substrate layer, an adhesive layer, a barrier layer, and a sealant layer are laminated in this order, the adhesive layer contains an ionomer (A) of an ethylene-unsaturated carboxylic acid copolymer, and a content of metal ions represented by X×Y/100 is equal to or more than 4.0 and equal to or less than 20.0 when a content of unsaturated carboxylic acid in an ethylene-unsaturated carboxylic acid copolymer (A1) constituting the ionomer (A) of the ethylene-unsaturated carboxylic acid copolymer is X [mass %], and a degree of neutralization of the ionomer (A) of the ethylene-unsaturated carboxylic acid copolymer is Y [mol %].

A terpolymer composition is described that contains a statistical amount of 50-98 wt % of a first repeating AA-BB comonomer unit; 1-25 wt % of a second repeating AA-BB comonomer unit; and 1-25 wt % of a repeating lactam comonomer unit or 1-25 wt % of a third repeating AA-BB comonomer unit, where the terpolymer composition exhibits a high melting point similar to that of PA66 while also exhibiting a significantly reduced crystallization rate and crystallization temperature.

A multilayer film for use in packaging organoleptic sensitive products has the structure seal/bulk/tie #1/core/tie #2/tie #3/odor barrier, in which the seal layer contains a homogeneous ethylene/α-olefin copolymer having a density of at least 0.906 g/cc. The odor barrier contains a polyester, amorphous polyamide, polycarbonate, polyvinylalcohol, and/or cyclic olefin copolymer. The 7-layer film above, and variants thereof, can be produced by coextrusion, extrusion coating, lamination (via adhesive, heat, etc). Packaging articles include pouches. Packaged products have the organoleptic sensitive product in the pouch made from the film, or made from a film without the odor barrier layer, with the pouch being sealed inside a separate bag containing the odor barrier layer.
