Abstract

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 byproducts of an oxygen scavenging reaction includes providing an article including an oxygen scavenger and a zeolite; and exposing the article to actinic radiation.
