OXYGEN SCAVENGER, OXYGEN SCAVENGER INTERMEDIATE, OXYGEN SCAVENGER COMPOSITE, AND PROCESS FOR PRODUCING THE SAME

摘要

An oxygen scavenger which comprises: an oxygen scavenger intermediate obtained by drying a sheet comprising an oxidizable metal and a fibrous material and formed by a papermaking method; and an electrolyte, as an oxidation aid, incorporated in the intermediate. The oxygen scavenger contains 0.1-10 mass% the electrolyte and has a water content of 5-70 mass%. The fibrous material preferably has a CSF of 600 mL or less. The oxidizable metal preferably is one at least 75% of which effectively undergoes a reaction.
