OXYGEN SCAVENGER COMPOSITION

摘要

An oxygen scavenger composition which comprises: 100 parts by weight of a support comprising a calcium silicate compound which is represented by the general formula CaO.mSiO2.nH2O (wherein m is 1.6 to 6.5 and n is a positive number) and has a corollaceous crystal structure which is an aggregate of curved flaky crystals comprising gyrolite-form calcium silicate and amorphous silicon dioxide; and more than 210 parts by weight of an easily oxidizable organic composition deposited on the support. The oxygen scavenger composition has high flowability and, hence, oxygen scavenger packages can be efficiently produced. The composition has a high oxygen absorption per unit volume and, hence, the oxygen scavenger packages can have a compact shape. Since inclusion of iron ingredients as impurities can be avoided, the oxygen scavenger composition is not detected with a metal detector.
