Abstract

An oxygen-absorbing composition (16) containing particulate annealed electrolytically reduced iron of between about 100 mesh and 325 mesh in an amount of about up to 99.6% by weight, a salt such as sodium chloride in an amount by weight of about up to 3.5 %, and optionally a water-attracting and supplying component such as silica gel of a mesh size of between about 30 mesh and 325 mesh in an amount by weight of up to about 80%. A packet (11) for absorbing oxygen including a stain and grease resistant envelope (27) containing the oxygen-absorbing composition (16). A grease and stain resistant laminate (27) con-sisting of plies of various plastics (17, 21, 22) and grease and stain resisting paper (19).
