Abstract
A system for triggering an oxygen scavenging film includes the means for emitting UV-C light, means associated with said light defining a film path, means for feeding an oxygen scavenging film into the system to trigger the oxygen scavenging film, means for feeding the triggered film to packaging means. The film may comprise an oxidizable organic compound and a transition metal catalyst.
Claims2
A packaging system, comprising:
- means for emitting UV-C light having a wavelength of between 200 and 280 nm;
- means for defining a film path associated with said means for emitting UV-C light;
- means for feeding a film having an oxidizable organic compound to said film path
- whereby said film is exposed to a dose of said UV-C light of at least 100 mJ/cm2 so as to provide a triggered film;
- means for feeding said triggered film to a means for packaging articles;
- and
- means for applying said triggered film to the articles to make packages;
- whereby said triggered film is continuously triggered and incorporated into said packages so as to provide oxygen scavenging packages.
