A laminate 10 comprising a first layer 12 containing a fluororesin, a second layer 14 containing a barrier material, a third layer 16 containing a fluororesin and a fourth layer 18 containing a polyamide in this order, wherein each of the fluororesin in the first layer 12 and the fluororesin in the third layer 16 is a fluororesin having a melting point of from 160 to 230° C. and having adhesive functional groups.

The present invention refers to a polymeric film comprising odor barrier material and being able to pack malodorous waste.

The present invention relates to a flexible packaging comprising a base layer and a film layer at least partially releasably affixed to the base layer via a pressure sensitive adhesive layer. The pressure sensitive adhesive layer comprises at least one adhesive zone and at least one adhesive-free zone extending continuously in a machine direction. The film layer is scored to form at least one pull tab which is disposed within the at least one adhesive-free zone and the base layer is scored to form at least one cavity which is disposed adjacent the at least one adhesive-free zone.

The present invention relates generally to the field of laminated packaging. In particular, the present invention relates to laminated flexible packaging comprising aluminium and a plastic sealant layer only on one side of the aluminium. One embodiment of the present invention relates to a laminated flexible packaging made at least in part from a laminated flexible packaging material comprising an aluminium foil layer, a plastic sealant layer and a coating, wherein the aluminium foil layer is laminated to the plastic sealant layer on the side facing the packaged product, the other side of the aluminium foil layer is coated with the coating but not laminated to a layer of plastic or paper, and wherein the laminated flexible packaging is manufactured from the laminated flexible packaging material on a horizontal form fill and seal (HFFS) machine.

A laminate 10 comprising a first layer 12 containing a fluororesin, a second layer 14 containing a barrier material, a third layer 16 containing a fluororesin and a fourth layer 18 containing a polyamide in this order, wherein each of the fluororesin in the first layer 12 and the fluororesin in the third layer 16 is a fluororesin having a melting point of from 160 to 230° C. and having adhesive functional groups.

Disclosed are compositions and methods for multilayer films, which, in one embodiment may comprise a core layer comprising at least 50 wt. % of high-density polyethylene. Further, the multilayer film may include a first skin layer comprising at least 80 wt. % of high-density polyethylene, and a second skin layer comprising either: (i) one or more low-density polyethylenes; or (ii) one or more polypropylene-based copolymers. The multilayer film may be oriented in at least one direction.

A multilayer laminate (100) comprises an oriented polyethylene film (102), a biaxially oriented film (104) adhered to the oriented polyethylene film (102), a barrier film (106) adhered to the biaxially oriented film (104), and a multilayer polyethylene (PE) film (108) adhered to the barrier film (106). The biaxially oriented film (104) comprises one or more components selected from biaxially oriented polyamide (BOPA), biaxially oriented polyethylene terephthalate (BOPET), and biaxially oriented polypropylene (BOPP).

A package comprises: a sterile barrier packaging film; self-sterilizing components comprising: a plurality of chlorite ions and water, wherein the self-sterilizing components are substantially free of an energy-activated catalyst and of an acid-releasing compound; a package interior formed by hermetically sealing the sterile barrier packaging film; and a headspace within the package interior comprising carbon dioxide present in an amount of greater than or equal to 5% by volume of the headspace. When the package is exposed to ultraviolet (UV) light having a wavelength of 254 nm, the chlorite ions react with the water to generate chlorine dioxide (ClO.sub.2), which is released into the headspace. In the absence of any UV light, there is not chlorine dioxide (ClO.sub.2) generation.

A laminate includes a multilayer outer film, which includes a first barrier layer and polyolefin layer on both sides of the first barrier layer, and a multilayer middle film, which includes a second barrier layer and polyolefin layer on both sides of the second barrier layer. The polyolefin layer of the multilayer outer film towards the multilayer middle film and/or the polyolefin layer of the multilayer middle film towards the multilayer outer film is metallized with a metal selected from aluminum, nickel, chromium, or combinations thereof. A process can be used for preparing the laminate and an article can include the laminate.

There is provided a resin composition, comprising an ethylene-vinyl alcohol copolymer and a nonionic surfactant, wherein the ethylene-vinyl alcohol copolymer has an ethylene unit content of 15 to 60 mol %, and a saponification degree of 90 mol % or more; the ethylene-vinyl alcohol copolymer is contained as a major component; and the nonionic surfactant is contained at 3 to 400 ppm. The resin composition is produced by melt-kneading a mixture comprising the nonionic surfactant, water and the ethylene-vinyl alcohol copolymer. By using the resin composition thus produced, a discharge amount during melt molding can be increased and a molded article with an excellent appearance can be provided.
