Barrier Foil Ziplock Pouches

Shown with our Specimen Storage Box, this barrier bag is ideal for storage of materials sensitive to moisture and/or oxygen. The inside dimensions measure L x H x W (where W is the pouch bottom width) with a zip lock and a tear notch above the zipper. The material is aluminum foil covered multi-layered polyethylene, providing an MVTR (moisture vapor transmission rate) that is 1,000 times better than a typical poly bag. They are heat sealable, and ziplock resealable. Compatible with vacuum sealers. Sizes to fit all your needs.
