Table for recommended desiccant usage. Information taken out of EIA-583, Table 1, Page 8.
*To measure interior bag surface area, multiply length x width x 2
**MIH = Maximum Interior Humidity (%)
Desiccant is a drying agent used to lower the moisture
content of air inside a closed space, such as a Moisture
Barrier Bag (ANSI/ESD S11.4 Level 1 and Level 2 Static
Control Bags). 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. The table is a reference indicating
recommended minimum amounts of desiccant that should be
used with Moisture Barrier Bags.
Desiccant paks are available from Desco in the following unit sizes and standard

“...it is important to take possible temperature exposure into account when shipping
electronic parts. It is particularly important to consider what happens to the interior of a
package if the environment has high humidity. If the temperature varies across the dew
point of the established interior environment of the package, condensation may occur. The
interior of a package should either contain desiccant or the air should be evacuated from the
package during the sealing process. The package itself should have a low WVTR.” (ESD
Handbook ESD TR20.20 section 5.4.3.2.2)
