Abstract: An article of manufacture includes an oxygen scavenger and an amorphous silica. 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 amorphous silica 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 an amorphous silica; and exposing the article to actinic radiation.

Abstract: A composite film and vacuum skin package for packaging a product such as a fresh red meat is disclosed. The composite film is thermoformed and sealed under vacuum to a support member to completely enclose a product which is positioned on the support member. The composite film is a permeable film weakly bonded to an impermeable film, permitting the impermeable film to be peeled from the package while leaving the permeable film intact so that the fresh red meat product can bloom from a purplish color to a desirable red color upon exposure to oxygen. The permeable and impermeable films are fully peelable without the need for a migratable wax to enhance peelability.
