Description
Desco Statshield^® Moisture Barrier Bags combine the
properties of a MOISTURE BARRIER protection with
EMI-RFI-ESD shielding. Statshield^® Moisture Barrier
Bags meet the electrical and physical requirements
of ANSI/ESD S20.20, Packaging standard ANSI/ESD
S541, and Static Control Bag ANSI/ESD S11.4. All
Statshield^® Moisture Barrier Bags are amide, amine,
and silicone free and pass outgassing and corrosion
tests. All bags are printed with ESD protective symbol
and the Moisture-Sensitive Identification Label and are
dated and lot coded for quality control traceability.
All three styles are available in a variety of standard
sizes, custom sizes and with custom printing.
Desco offers three styles of Moisture Barrier Bags:

Construction
Desco’s Statshield^® Moisture Barrier Bags
manufactured from a static dissipative metalized
laminated film. The metal layer of the Desco’s
Statshield^® Moisture Barrier Bags and Statshield^® High
Moisture Barrier Bags is created by vacuum deposited
manufacturing technique. This manufacturing
technique allows for a more flexible finished bag that is
less likely to tear or rip during use. Finished bags with
foil layer, such as Desco’s Statshield^® Foil Moisture
Barrier Bags provides a better moisture barrier and
is a good choice when having to meet IPC/JEDEC
J-STD-033 Standard.
