A method for triggering an oxygen scavenging component of a container (10) for packaging an oxygen sensitive material includes the steps of providing a container (10) defining an internal space and having an internal oxygen scavenging component including an oxidizable organic compound and, optionally, a transition metal catalyst, exposing said 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 said oxygen scavenging component, and packaging an oxygen sensitive material in the internal space of the container whereby the oxygen scavenging compon ent scavenges the oxygen from the internal space of the container. An apparatus and packaging system are also disclosed.

Procédé pour activer un composant désoxygénant d'un récipient pour emballer un matériau sensible à l'oxygène, consiste à prévoir un récipient définissant un espace interne et comprenant un composant désoxygénant interne contenant un composé organique oxydable et, éventuellement, un catalyseur à métal de transition, à exposer ledit composant désoxygénant à une source de rayonnement actinique placée dans ledit espace interne, à une certaine longueur d'onde, intensité et pendant un certain temps de séjour, de sorte qu'une dose de rayonnement actinique suffisante pour l'activation dudit composant désoxygénant soit produite, et à emballer un matériau sensible à l'oxygène dans l'espace interne du récipient, ledit composant désoxygénant enlevant l'oxygène de l'espace interne du récipient. Un appareil et un système d'emballage sont également décrits.
