Barrier Foil Ziplock Bags

Barrier bags are ideal for storage of materials sensitive to moisture and/or oxygen. The inside dimensions measure 6 x 5.5″ with a zip lock and a tear notch above the zipper. The material is a metal foil-covered 4mil polyethylene with a MVTR (moisture vapor transmission rate) that is 1,000 times better than a typical poly bag. Bags are heat sealable and ziplock resealable. Compatible with vacuum sealers.
