<p>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. As alkali metal oxide, lithium oxide, sodium oxide or potassium oxide can be designated and, as alkaline earth metal oxide, magnesium oxide calcium oxide or strontium oxide can be designated. As the thermoplastic resin, polyester or polyamide is used.</p> |
