Desiccant is a drying agent used to lower the moisture content of air inside a closed space, such as a Moisture Barrier Bag. Desiccant is packaged in fractional units in order to facilitate its usage with a variety of bag sizes. One full “unit” of packaged desiccant will absorb the following quantities of water at equilibrium with air at 77°F (25°C): 3.00 grams @ 20% rH and 6.00 grams @ 40% rH, when tested to MIL-D-3464. In order to provide a complete moisture barrier packaging assembly, desiccant must be inserted into the bag, prior to having the bag vacuum sealed. The recommended amount of desiccant is dependent on the interior surface area of the bag to be used. Figure 4 is a reference table indicating recommended minimum amounts of desiccant that should be used with Moisture Barrier Bags. INTERIOR BAG NUMBER OF DESICCANT UNITS SURFACE AREA* **MIH
