Patent

CA 2262486

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.

L'invention porte sur un procédé d'activation de films absorbeurs d'oxygène consistant à produire un film absorbeur d'oxygène comportant un composé organique oxydable et, facultativement, un catalyseur en métal de transition, puis à exposer ledit film à une source d'UV-C d'une intensité et d'une durée suffisantes pour que l'irradiation du film soit d'au moins 100 mJ/cm<2>. L'invention porte également sur un appareil et un système de conditionnement.
