• 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

Construction

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.
