An article of manufacture includes an oxygen scavenger and a zeolite. The article can be in the form of e.g. a film or sealing compound. A package can be made from the article for containing an oxygen-sensitive article such as food. The zeolite reduces migration of odor causing by-products of the oxygen scavenging process. A method of making an article of manufacture having reduced migration of by-products of an oxygen scavenging reaction includes providing an article including an oxygen scavenger and a zeolite; and exposing the article to actinic radiation.
Un article manufacturé comprend un désoxygénant et un zéolite. Il peut se présenter sous forme, par exemple, d'un film ou d'un composé obturant. Il est possible de fabriquer à partir dudit article un emballage contenant un article sensible à l'oxygène, tel qu'un produit alimentaire. Le zéolite diminue la migration des sous-produits du processus de désoxygénation qui provoquent la formation d'odeurs. Un procédé permettant de fabriquer un article manufacturé, dans lequel la migration des sous-produits de la réaction de désoxygénation est réduite, comprend la fabrication d'un article contenant un désoxygénant et un zéolite, puis l'exposition dudit article à un rayonnement actinique.
