Moisture Barrier Bags
3M is one of the leading manufacturers of moisture bags, offering short
lead times for custom bag sizes to fit your application. Bags are marked
with Moisture and ESD caution information, RoHS compliant symbols,
and are lot coded for traceability. Custom printing is available. Moisture
barrier bags are designed to protect electronic items from moisture,
electrostatic, physical and environmental damage during manufacture,
transportation, and storage. As required in ANSI/ESD S541, and as part
of the ANSI/ESD S20.20 ESD control program, barrier bags provide
protection from static discharge and are low charging.
Types of Barrier Bags
IPC/JEDEC J-STD-033 for Devices
Surface mount devices (SMD) are attached to circuit boards by reheating
solder on the pads. This technique, called reflow soldering, heats the
circuit board, device leads and the device case. Moisture trapped inside
the device case can expand at a rate faster than the case, causing the
case to rupture. To prevent this damage, the IPC/JEDEC J-STD-033
standard sets requirements for foil barrier bags, desiccant, humidity
indicator cards, labeling and bag sealing. 3M supplies all of the items
needed for compliance.
MIL-PRF-81705 for Assemblies
Disk drives, bare cards, and other components are subject to corrosion
during storage and shipment. Metallized moisture barrier bags that meet the
barrier limit established in MIL-PRF-81075 can help to prevent this damage.
Get all the parts to meet IPC/JEDEC J-STD-033: See page 76 for bags,
page 80 for HICs and page 81 for desiccants, labels and sealers.

Bags for IPC/JEDEC J STD-033 MVTR
Dri-Shield 3000
Moisture Barrier
Bag, Foil, 6 mil
Designed to meet the requirements of IPC/
JEDEC J-STD-033 for the dry packaging of
electronic devices. Dri-Shield 3000 bags are
made from dissipative nylon, foil, and
dissipative polyethylene. These bags protect
SMDs from moisture and static damage.
Flexible structure is easy to vacuum seal.
Lot coded for QC traceability.
Dry packaging of devices in
compliance with IPC/JEDEC
J-STD-033.
76
Dri-Shield 3400
Moisture Barrier
Bag, Foil, 4 mil
For dry packaging of electronic devices.
Dri-Shield 3400 bags are made from a high
barrier foil structure. Bags protect SMDs
from moisture and static damage. Flexible
structure is easy to vacuum seal. Lot coded
for QC traceability.
Value packaging: Higher puncture
resistance with less thickness. Dry
packaging of devices in compliance
with IPC/JEDEC J-STD-033.
76
Puncture Resistant
Dri-Shield 3700
Puncture Resistant
Moisture Barrier
Bag, Foil
Bags provide superior puncture resistance
and drop test performance. This reduces
vacuum loss due to punctures from sharp
trays and rough handling. Also meets the
requirements of IPC/JEDEC J-STD-033 easy
to vacuum seal. Lot coded for QC traceability.
Highest puncture resistance to
reduce vacuum loss. Dry packaging
of devices in compliance with
IPC/JEDEC J-STD-033.
77
Low Voltage Retention (Metal-Out)
Dri-Shield 3200
Metal-out Moisture
Barrier Bag, Foil,
3.6 mil
Metal-out structure meets the dry packaging
requirements of IPC/JEDEC J-STD-033, and
provides charge retention of less than 50 volts.
This combination of technology helps prevent
static damage to transient-sensitive devices.
Low voltage retention for sensitive
devices. Dry packaging of devices
in compliance with IPC/JEDEC
J-STD-033.
