An oxygen scavenger composition includes an organic oxygen scavenger, a transition metal catalyst, and a blend of at least two photoinitiators selected from 1,3,5-tris(4-benzoylphenyl)benzene, thioxanthone derivative, acyl phenylphosphineoxide derivative, and diphenyl sulfide derivative. A film includes at least one layer including an organic oxygen scavenger, a transition metal catalyst, and a blend of at least two photoinitiators selected from 1,3,5-tris(4-benzoylphenyl)benzene, thioxanthone derivative, acyl phenylphosphineoxide derivative, and diphenyl sulfide derivative. A method of triggering an oxygen scavenger composition includes providing an oxygen scavenger composition including an organic oxygen scavenger, a transition metal catalyst, and a blend of at least two of 1,3,5-tris(4-benzoylphenyl)benzene, thioxanthone derivative, acyl phenylphosphineoxide derivative, and diphenyl sulfide derivative; and subjecting the oxygen scavenger composition to a dosage of actinic radiation effective to trigger the oxygen scavenger composition.
