Our DRYLOK® 8850 Static Shielding/Moisture Barrier Bag is engineered for maximum protection of sensitive components from electro-static shock and moisture.

DRYLOK® 8850 bags are available in several standard sizes designed to contain matrix trays, tubes and 13” shipping reels and custom sizes can be made to fi t the needs of nearly any project. When used with the Advantek® Desiccant and Humidity Indicator Cards, The DRYLOK® 8850 bags provide superior protection for Static- and moisture-sensitive devices.

• 5.5 mil thick static dissipative polyester, aluminum foil, nylon and static dissipative polyethlene layer construction provides superior puncture resistance with low MTV

• Meets the requirements of EIA 541 & IPC/JEDEC J-STD-033


DRYLOK® 8850 Static Shielding/Moisture Barrier Bags are constructed in four layers. The bag features an anti-static metallized polyester outer layer and a black antistatic inner layer. In between are layers of polyethylene, nylon and an aluminum foil shield.
