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.

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.

A co-extruded, multilayer film for packaging freshly cut produce consists of (1) an outer layer of an ethylene/propylene/4-8 C alpha-olefin terpolymer, (2) a middle layer containing at least one of (a) 0-100% of the terpolymer described in (1) and (b) 0-100% of a blend of (i) about 99.5% to about 95% of an olefin copolymer composition made by sequential polymerization in at least two stages and (ii) about 0.5% to about 5% of a low density polyethylene, wherein (a)&plus;(b)&equals;100%, and (3) an inner layer containing at least one of (a) 0-100% of a copolymer of ethylene and a C,-C,alpha-olefin made using a metallocene catalyst and having a density of 0.89 to 0.91 g/cm,, and (b) 0-100% of blend (b) described in layer (2), wherein (a)&plus;(b)&equals;100%. The thickness ratios of the layers and, when both components are present, the amount of each polymer in the blends of layers (2) and (3) can be varied to match the gas transmission rate of the produce to be packaged.
