Introduction
Corrosion and thus moisture protection is becoming
increasingly important. From ESD Association 22nd
EOS/ESD Symposium Proceedings*, “As electronic
components use less material they become more
sensitive to voltage and current variations. This
increases their operational speed and functionality.
Corrosion that was heretofore inconsequential now
becomes a major factor in the current electronic
components. . . . This underlines the importance of
protection from angstrom level corrosion of surfaces
beyond the normal solderability level problems on
circuitry.” Statshield
Bags addresses this concern providing physical, ESD,
EMI/RFI, and moisture protection.
"...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)

Description
Desco Statshield
properties of a MOISTURE BARRIER constitution with
EMI-RFI-ESD shielding. Statshield
Bags meet the electrical and physical requirements of
ANSI/ESD S541, EIA 583, EIA 541, EIA 625, and MIL-
PRF-81705D, Type I. All Statshield
Bags are amide and amine free and pass outgassing
and corrosion tests. All bags are printed with ESD and
moisture warning symbols and are dated and lot coded
for ease of traceability.
Desco offers three styles of Moisture Barrier Bags. The
first is a .0065” (.1651mm) thick heavy-duty bag with
EMI shielding, the second is a .0040” (.1016mm) thick
foil bag with EMI/RFI shielding, and the third is a
.0035” (.0889mm) bag with EMI/RFI shielding
properties. All three bags are available in a wide range
of sizes. Also, custom sizes and custom imprinting are
available.
Construction
Desco Statshield® Moisture Barrier Bags are
manufactured out of a laminated film which features
static dissipative surfaces. The configuration is similar
to the metal-in shielding material, but with two metal
layer being placed between layers of dissipative film. A
polyester layer provides pull strength and heat seal
capability. The metal layer is approximately ten times
thicker than that of traditional static shielding material
and provides the EMI attenuation and moisture barrier
properties.
The metal layer within the Moisture Barrier Bag is
vacuum deposited rather than being a foil layer. This
difference allows the bag to be much softer and
flexible, therefore the metal portion of the bag is less
likely to tear or rip providing a more reliable barrier
against moisture and static electricity.
