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. 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.
Desiccant paks are available from Protektive Pak in the following unit sizes and
standard packages:

“...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)
