PROBLEM TO BE SOLVED: To obtain an oxygen-absorbing sheet reduced in the formation of odors resulting from the deterioration of the resin and having improved oxygen- absorbing performances by molding a mixture of a thermoplastic resin powder with an oxygen absorber into a sheet. SOLUTION: Fifteen (15) to 70wt.% thermoplastic resin powder having a mean particle diameter of 100μm to 3mm and 85-30wt.% oxygen absorber having a mean particle diameter of 10-300μm and a specific surface area of 500cm<2> /g or above are fed into a high-speed powder mixer and mixed with each other under heating and agitation in a nitrogen gas atmosphere while the temperature in the jacket is being raised to obtain a mixed powder. This powder is fed into a singlescrew extruder and extruded into an oxygen-absorbing sheet having a thickness of 10μm to 5mm. |
