PROBLEM TO BE SOLVED: To provide a method for preserving an oxygen-absorbing resin composition for a long time without reducing oxygen-absorbing ability of an oxygen- absorbing polyamide resin composition between a term ranging from finishing production of master pellets comprising the oxygen-absorbing polyamide resin composition to processing them to various packaging materials. SOLUTION: The oxygen-absorbing polyamide resin composition contains one or more species of metal atoms selected from transition metals of the VIII group in the periodic table of elements, manganese, copper and zinc. The method for preserving the oxygen-absorbing resin composition is to preserve the composition in a preservation container made by using a metal foil or a metal plate. COPYRIGHT: (C)2004,JPO |
