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.
