An oxygen scavenging composition of a polymer which is permeable to both oxygen and water or water vapor, and an oxygen scavenging material of an amino polycarboxylic acid chelate or complex of a transition metal, or salt thereof, dispersed relatively uniformly throughout the polymer in an amount effective to act as an oxygen scavenger when activated for scavenging oxygen by contact with water or water vapor which permeates the polymer. A preferred oxygen scavenging compound is ferrous EDTA or salts thereof. Also, an ascorbate compound may be used as a preservative or augmenter for the oxygen scavenging compound.
