  • Patent number: 6103141
    Abstract: An adhesive desiccant deposit comprising a hot melt adhesive and a desiccant dispersed within the hot melt adhesive. The hot melt adhesive has sufficient porosity to allow water molecules to pass into the hot melt adhesive and contact the desiccant. The hot melt adhesive may optionally contain an additive to increase the porosity of the hot melt adhesive. One particular application of the deposit involves an adhesive desiccant tape comprising a substrate, a first adhesive layer disposed on the bottom of the substrate, a removable liner disposed on the first adhesive layer on the side of the first adhesive layer away from the substrate, and an adhesive desiccant deposit disposed on the top of the substrate.

  • Patent number: 5686161
    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.
