Abstract

A method for triggering an oxygen scavenging component of a container for packaging an oxygen sensitive material includes the steps of providing a container defining an internal space and having an internal oxygen scavenging component including an oxidizable organic compound, exposing the oxygen scavenging component to a source of actinic radiation, positioned within said internal space, at a wavelength, intensity, and residence time so as to provide a dose of actinic radiation sufficient to activate the oxygen scavenging component, and packaging an oxygen sensitive material in the internal space of the container whereby the oxygen scavenging component scavenges the oxygen from the internal space of the container. An apparatus and packaging system are also disclosed.
