Abstract

A sealed container material having a deoxidation function comprises a metallic base material reactive with oxygen and a hydrophilic coating layer of water-soluble polymer such as hydroxyethyl cellulose formed on the surface of the metallic base material. An oxygen- and moisture-permeable coating layer composed of a silicone resin or an olefin resin may further be provided on the hydrophilic coating layer. The material exhibits an excellent oxygen absorbing ability and is thus suited as a material for sealed containers, such as cans, bottles, capsules, etc., for encasing food, drink, chemicals, and medical drugs and storing them over a long period of time without denaturation or deterioration.
