Activated Clay unit bags exceed the requirements of Mil-D-3464E in actual performance and will exceed the moisture vapour adsorption of silica gel at government specifications levels. Activated Clay 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.

Activated Clay performance curve exceeds both military specification, which is the industry standard, and the silica gel performance curve for these same specifications.

At 20% RH, Activated Clay 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.

Activated Clay meets Method II packaging standards described in Mil-P-116E, which covers the basic requirement of military packaging methods of preservation.

This involves packaging an item inside a sealed waterproof and moisture vapour-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.

Stream Peak offers unit size bags to meet any challenge that requires moisture protection whether it is food, military, bulk items, or storage.
