Abstract: An absorbent packet for absorbing water vapor. The absorbent packet comprises a gas permeable, multi-layered packaging material which absorbs water vapor, but does not permit liquid water within the packet from flowing back through the packaging material, wherein the packaging material preferably comprises a microporous film, a gas permeable film and a binder to bind the microporous film to the gas permeable film, and an absorbent material incorporated between the layers of the multi-layered packaging material. This absorbent packet is particularly useful for absorbing water vapor in shipping containers where changes in the atmospheric conditions result in variable relative humidity in the shipping container.

Abstract: A desiccant canister comprised of a generally cylindrical body portion, first and second end portions, and at least one gas permeable disk-shaped member, wherein the body portion is generally impermeable to liquids and gases, wherein at least one of the said end portions is perforated, and wherein the disk-shaped member is secured to the end portion of the canister containing perforations.

Abstract: Formed is a new desiccant film made of an uncoated microporous film secured to an uncoated laminate film wherein the inner surface of both the microporous film and the laminate material are compatible. This film is less expensive to form and produces a stronger bond than conventional coated materials used for desiccant packaging.
