Desi-Pak® Clay Desiccant

DESI PAK® clay desiccant bags contain a highly activated, chemically inert and noncorrosive desiccant which absorbs moisture vapor through the capillary action of adsorbent particles without changing the physical shape of the particles or the bag.

Your most efficient and cost effective form of humidity protection during shipment and storage, Desi-Pak desiccant bags are in stock and ready for immediate shipment from Texas Technologies.

Desi Pak® unit bags exceed the requirements of Mil-D-3464E in actual performance and will exceed the moisture vapor adsorption of silica gel at government specifications levels. Desi Pak® montmorillonite clay is a naturally occurring mineral as opposed to the chemically synthesized adsorbent. Therefore it is more economical than silica gel or molecular sieve.

The Desi Pak® performance curve exceeds both the military specification, which is the industry standard, and the silica gel performance curve for these same specifications.

At 20% RH, Desi Pak® will adsorb 50% more moisture than required by Mil-D-3464E, whereas silica gel will only adsorb 3.5% more moisture than required by Mil-D-3464E.

Desi Pak® meets Method II packaging standards described in Mil-P-116-E, which covers the basic requirement of military packaging methods of preservation. This involves packaging an item inside a sealed waterproof and moisture vapor-proof container with the inclusion of a desiccant to prevent rust, mildew or corrosion damage. In Method II packaging, the package is maintained at a safe humidity below 40% RH during the normal storage period of 18 months to 2 years.

DESI PAK® is a low cost efficient desiccant which will protect the contents of a sealed container until it is opened. When used in conjunction with a humidity indicator, the contents of a sealed container will remain free from mildew or corrosion and will be in the same condition as when packaged for shipment or storage.

United Desiccants' DESI PAK® Tyvek® bags were tested by an independent laboratory for Class 100 Cleanroom use. The 1/6, 1/2, 1/3, 1, 2, 4 and 8 unit bags containing clay desiccant were evaluated. All bags tested emitted less than 100 particles 0.5 microns in size or larger per cubic foot of air, thereby certifying DESI PAK® bags as Class 100 cleanroom compatible.

Meets FDA Specifications

DESI PAK® Tyvek® activated clay desiccant bags meet the requirements of the U.S. Food and Drug Administration for use in contact with food and drugs.
