DRYLOK® 4400 Static Shielding/Moisture Barrier Bag


The DRYLOK® 4400 from Advantek® is a transparent polyester ESD static shielding/moisture barrier bag. This distinctive transparent bag uses a unique aluminum vapor coating layer, providing protection to bag contents from both electro-static shock and moisture.

DRYLOK® 4400 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® 4400 bags provide superior protection for Static- and moisture-sensitive devices.

• 3.3 mil thick transparent polyester construction to provide inspection capability with good puncture protection

• Meets requirements of EIA 541 & EIA 583

• Strong puncture resistance ensures vacuum seal integrity and protects contents of bag for up to 2 years


DRYLOK® 4400 Static Shielding / Moisture Barrier Bags are constructed in seven layers. These consist of a static dissipative outer layer followed by a polyester fi lm layer and a proprietary aluminum vapor coat. In the middle is a second polyester layer followed by an adhesive layer. Rounding out the DRYLOK® 4400 is a polyethylene layer and a final static dissipative coating.


DRYLOK® 3410 Static Shielding/Moisture Bags are available in custom sizes or in several industry standard sizes designed for reels, matrix trays and tubes. Bags are offered in a 2-seal confi guration with a bottom fold or a 3-seal configuration, each with our standard Advantek hot-stamp or your company’s hot-stamped or flexographically printed logo.
