Abstract
An oxygen-absorbing label consisting of a base sheet, adhesive on the base sheet for securing the base sheet to an internal surface of a container, an oxygen-absorbing composition on the base sheet, and a cover sheet secured to the base sheet to confine the oxygen-absorbing composition therebetween, the cover sheet being fabricated of material which will permit oxygen to pass therethrough but will not stain due to the oxidation of the oxygen-absorbing composition or due to contact with materials in the container. A plurality of the foregoing labels are mounted on a web to be used with conventional labeling equipment.
