In the oxygen absorbent for resin blending of the present invention, as a mixed powder containing iron, a metal halide and an alkaline substance, the half width of the peak at the (110) plane measured by the powder X-ray diffraction method of the mixed powder is 0.20 ° / 2θ (Co-Kα) or less, specific surface area of 0.5 m 2 / g or more, and an average particle diameter of 1 µm to 40 µm, which effectively suppresses generation of hydrogen, is excellent in safety, and excellent oxygen absorption. Moreover, since it has the performance and generation | occurrence | production of the coarse particle in an oxygen absorber manufacturing process is suppressed, it has the characteristic that productivity is high. In addition, the oxygen absorbent container having a layer made of an oxygen absorbent resin composition containing an oxygen absorbent for resin blending of the present invention has excellent storage properties, small surface irregularities and excellent appearance characteristics, There is no risk of swelling or bursting. |
