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.
