摘要

An article of manufacture includes an oxygen scavenger and poly(lactic acid). The article can be in the form of a film, coating, gasket, liner, insert, sealant, or fibrous matte. A film includes at least one layer including an oxygen scavenger, and at least one layer including poly(lactic acid). A package can be made from the film for enclosing an oxygen-sensitive article such as food. The poly(lactic acid) blocks the migration of odour caused by-products of the oxygen scavenging process. A method includes providing a film including at least one layer including an oxygen scavenger; and at least one layer including the poly(lactic acid); and exposing the film to actinic radiation. A method for reducing migration of organoleptically significant compounds is also disclosed.
