Dri-Shield moisture barrier bags in the 18 x 18 inch format combine a 3.6 mil multi-layer film construction with both heat-seal and vacuum-packaging compatibility, delivering a tight, airtight closure that controls moisture vapor transmission and dissipates electrostatic charge to protect sensitive contents.

These bags serve electronics manufacturers packaging PCBs, assemblies, and discrete components, as well as contract packagers, defense supply chain operations, and industrial storage environments where humidity-sensitive materials must be sealed against ambient moisture during long-term storage or transit.

The multi-layer film works with standard heat-sealing equipment and requires no specialized tooling for vacuum applications. Each case contains 100 bags. Note: This product is intended for commercial use and is not listed on the Qualified Products List under the Defense Standardization Program.
