Abstract: An oxygen absorbing composition having an effective amount of at least one oxygen absorbent contained in an emulsion. An oxygen absorbing product is produced by dispersing an oxygen absorbent in an emulsion, dispersion, or suspension to form an oxygen absorbing composition and transferring the oxygen absorbing composition onto a substrate. A cover layer is disposed over the oxygen absorbing composition.

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.

Alternatively, the moisture barrier sheets have a desiccant deposit attached to them. Also alternatively, a pouch with a desiccant deposit attached to its inner surface contains the test strip.

Abstract: A container cap having a base portion, a substantially cylindrical portion extending perpendicularly from a perimeter of the base portion to define an inner surface of the container cap, and an uncovered liner disposed directly on the inner surface of the container cap, the liner having an oxygen absorbent dispersed therein. The container cap is adapted to seal an opening in a container and to absorb oxygen within the container. Also disclosed is a method for removing oxygen from a container by dispersing an oxygen absorbent in a liner, attaching the uncovered liner directly to an inner surface of a container cap without a separate adhesive, and placing the cap over an opening in the container such that the liner in the container cap seals the opening and absorbs oxygen within the container.
