Abstract:
PROBLEM TO BE SOLVED: To obtain a safe and inexpensive oxygen absorbable compsn. having high oxygen absorbing capacity by mixing aluminum, one metal oxide selected from alkali metal oxides and alkaline earth oxides and a thermoplastic resin.
SOLUTION: Aluminum, one metal oxide selected from alkali metal oxids and alkaline earth oxids and a thermoplastic resin. are mixed. It is unnecessary to purify aluminum to especially high purity and aluminum in a form suitable for grinding and mixing can be used.
