A method of forming a desiccating part including the steps of: (a) blending a composition comprising: at least 60 wt % desiccant, up to 10 wt % wetting agent, up to 5 wt % processing aid, and 10-30 wt % thermosetting resin; (b) forming the composition blended in step (a) into a part or shape; and (c) heating the part or shape of step (b) to crosslink the resin. Also included is a desiccating part comprising at least 70 wt % desiccant and a thermosetting binder resin.

Thermoset desiccant product and method for making same

The invention relates to an article for oxygen absorption that is a container containing a water-soluble on source, a water activated oxygen scavenger, and a rupturable canister of hydrated polymer. The hydrated polymer comprises a superabsorbent polymer. The water-soluble on source comprises a salt. The invention in another embodiment relates to a method for providing timed oxygen absorption using the article as above with rupturing of the canister to release the water carrying superabsorbent such that it will contact the oxygen scavenger and on source thereby leading to activating the oxygen scavenger.

Controlled release of water to an oxygen scavenger

The invention relates to a moisture indicator which includes iodide, copper, and starch.

Copper, starch and iodide moisture indicator

An oxygen-absorbing composition for use as a component of a plastic packaging material that includes in relatively sufficient proportions iron, acidifier, and electrolyte.

Pressed adsorbent and method of fabrication thereof

A composition for absorbing oxygen and releasing carbon dioxide in a high moisture environment including by weight an iron-based component for absorbing oxygen in an amount of between about 15% and 60%, a carbon dioxide releasing component for releasing carbon dioxide in an amount of between about 8% and 50%, an acidifying component for providing acid for activating the carbon dioxide releasing component, and a dry water-attracting component for preventing premature activation of the iron-based component and carbon dioxide releasing component and for attracting water from a high moisture environment to thereby supply water for activating the acidifying component and the iron-based component. A method of absorbing oxygen and releasing carbon dioxide in a container having a product and a high moisture environment and wherein oxygen was flushed out and replaced by at least 26% carbon dioxide and the remaining atmosphere in the container having 17% or less oxygen content after the flushing and into which additional oxygen may have entered including the steps of providing a container, placing a product into the container, flushing the container with a gas containing carbon dioxide, and inserting into the container a packet containing the above described composition.

Composition for and method of absorbing oxygen in an oxygen/carbon dioxide environment

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.

Oxygen absorbing composition with cover layer

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.
