Abstract
An oxygen-absorbing composition (16) is contained in an envelope (11) of spun-bonded polyolefin with a seam (12), having the first end portions fused at (14) and the second end portions fused at (18). The oxygen-absorbing composition (16) contains a particulate annealed electrolytically reduced iron (about 100 to about 325 mesh) in an amount up to 63 % by weight, a salt such as NaCl in an amount up to about 3.5 %, and a water-supplying component comprising activated carbon (about 20 to about 50 mesh) with liquid water therein to the amount of up to about 85 % of the composition in an envelope (11) which will resist the passage of liquid water out of the envelope, but will permit flow of oxygen into the envelope at a satisfactory rate.
