An article comprised of polymeric protective material having incorporated therein a dry oxygen scavenger material, the oxygen scavenger material being capable of a passive state for prolonged periods of time during which the oxygen scavenger will not directly react with oxygen, and triggerable to an active state when wetted with water which has selectively permeated the protective material from outside the article, whereupon the oxygen scavenger will directly react with oxygen, wherein said protective material is substantially resistant to permeation by water at ambient temperature and has enhanced transmission of water at elevated temperatures and therefore is selectively capable of permeation by water at elevated temperatures to thereby selectively permit the water to contact said oxygen scavenger material to convert it from the passive to the active state.
