Moisture Absorbing Desiccant
Desi Pak ® packaged clay desiccant is a low-cost, efficient desiccant which will protect the contents of a properly sealed     
container during shipping and storage. The contents of a sealed container will be in the same condition as when it was
packaged for shipment or storage.

The addition of a humidity indicator card in each Desi Pak container allows the container to be visually inspected to
insure that the desiccant remains active and the contents safe.

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

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

Tyvek® Tyvek® is a DuPont registered trademark.
Desi Pak Tyvek® bags are non-dusting. Tyvek® bags contain no sulphur. Sulphur when placed in contact with a product, may cause corrosion in many applications such as the electronics industry. Tyvek® is made from high density polyethylene fibers, is a spunbonded olefin, and is extremely tear-resistant. Mil-D-3464 dust testing has yielded a result of less than 0.5 mg of dust - truly a dust-free desiccant.

Meets FDA Specifications

Desi Pak Tyvek bags meet the requirements of the U.S. Food and Drug Administration for use in contact with food and drugs.

Class 100 Clean Room Compatible

Desi Pak Tyvek® bags were tested by an independent laboratory for Class 100 Clean Room use. The 1/8, 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 Clean
Room Compatible.

At 20% RH, Desi Pak will adsorb 50% more moisture than required by Mil-D-3464, whereas silica gel will only adsorb 3.5% more moisture than required by Mil-D3464.  Drum Shelf life (5 Years)

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.
