An oxygen scavenger film includes a layer including an oxygen scavenger, and a layer including a cyclic olefin copolymer. An oxygen scavenger film includes a layer including a blend of an oxygen scavenger, and a cyclic olefin copolymer. A method of triggering an oxygen scavenger film includes providing an oxygen scavenger film including a layer including an oxygen scavenger, and a layer including a cyclic olefin copolymer; and subjecting the oxygen scavenger film to a dosage of actinic radiation effective to trigger the oxygen scavenger.
