Abstract:
Disclosed herein is a method of initiating oxygen scavenging in a packaging article comprising an oxygen scavenging polymer. The method involves (i) providing the packaging article comprising the oxygen scavenging polymer, wherein the packaging article comprises an interior surface and an exterior surface; (ii) wetting the interior surface of the packaging article with a solution comprising a peroxide, to result in a packaging article with a wetted surface; and (iii) exposing the wetted surface to an initiating factor, to initiate oxygen scavenging by the packaging article. Typically, the initiating factor is ultraviolet light, heat, or both.
Abstract:
Polymeric carpet and a method of making and recycling such carpet, the carpet having fibers, backing and extruded adhesive all of completely recyclable materials, the recycling being accomplished in one melting step, without a separation step.

Abstract:
Oxygen scavenging materials incorporated into or attached to a package such as a gable-top or rectangular carton, used to package foods, beverages or other oxygen sensitive materials, and thereby increase shelf-life by decreasing oxygen in the headspace of the package, and decreasing oxidation of the packaged product.

Abstract:
The techniques disclosed provide methods for making and using lamination films having one, two, three or more layers. The two layer lamination films may have an outer protective material comprising a styrenic polymer and an inner sealing material comprising a poly(ethylene vinyl acetate) (EVA). The three layer lamination films add a center adhesive layer comprising a blend of a low density polyethylene and an EVA. Laminated structures using said lamination films are also described.

Abstract:
Methods and systems are disclosed for initiating oxygen scavenging in an angular preformed packaging article comprising an oxygen scavenging layer. The packaging article is moved into and out of a chamber, in which it is exposed to UV radiation of at least about 280 nm. The wavelength of UV radiation to which the article is exposed can be selected so that it will be absorbed by the oxygen scavenging layer as efficiently as possible, taking into account the composition of the oxygen scavenging layer and any additional layers that are present.
