Abstract
An oxygen-absorbing label and a moisture-sensitive label. The oxygen-absorbing label consists 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 permeable cover sheet secured to the base sheet to confine the oxygen-absorbing composition therebetween. The moisture-sensitive label is one wherein a moisture-sensitive material is used as part of the label instead of the oxygen-absorbing composition. The moisture-sensitive material may be a moisture adsorber such as silica gel or molecular sieve, or it may be a moisture supplier such as hydrogel. A plurality of the foregoing labels are mounted on a web to be used with conventional labeling equipment.
