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:

Notes:
Thickness - Typical value. Nominal ±10% per
MIL-STD-3010 1003
Moisture Barrier Transfer Rate (MVTR) - Measured
per ASTM F1249 (g/100 sq.in./24 hrs, at 100F)
Puncture Resistance – measured per
MIL-STD-3010 2065
Construction
manufactured from a static dissipative metalized
laminated film. The metal layer of the Desco’s
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
provides a better moisture barrier and
is a good choice when having to meet IPC/JEDEC
J-STD-033 Standard.
