In the food processing area, these bags are known as oxygen barrier bags. Many people refer to them as Mylar® Foil bags because the outer layer of the bag is Mylar® Foil, which is a brand name for the Dupont Corporation's polyester film. Our Mylar® Foil bags are 5-layer structures of Mylar® Foil/polyethylene /00035 aluminum foil/adhesive/linear low-density
OXYGEN BARRIER BAGS (Mylar® FOIL BAGS) will greatly increase the shelf stability of your food products. Polyethylene pails are not a true oxygen barrier by themselves. The oxygen transmission rate is critical. (OTR) for example, our bags have a transmission rate of 0.001 cc's of oxygen per square meter per 24 hours. A clear mylar®/poly bag is 0.5 cc's/ square meter/ 24 hours, or 500 (FIVE HUNDRED!) times greater.
WARNING: Some companies and people will try to tell you that clear "FOODSAVER" bags are good for long term storage. THEY ARE NOT.
We recommend our Two Cup and Quart Mylar bags for your storage (1-5 years) and for your snacking pleasure. Most customers that purchase these "gold" pouches intend for the product to be continuously used and consumed over a short time: 1-5 years.
These Mylar® Foil bags measure 20 by 30 inches and are perfect for BULK storage.
