Method, apparatus, and system for triggering oxygen scavenging films

摘要

A method for triggering an oxygen scavenging film includes the steps of providing an oxygen scavenging film comprising an oxidizable organic compound and, optionally, a transition metal catalyst; and exposing the film to a source of UV-C light at a wavelength, intensity and residence time sufficient to provide the film with a dose of UV-C light of at least 100 mJ/cm2. An apparatus and packaging system are also disclosed.
