Mylar bags are a homesteader's best kept secret to effectively protect dry foods against light, moisture, scents and insects long-term. Simply seal your Mylar food storage bag with a flat iron or one of our impulse sealers to extend the shelf life of your favorite foods. Don't forget to tuck an oxygen absorber inside your Mylar bag before you seal it to prolong the shelf life of your food. For an easy way to start storing food in Mylar bags, check out our starter kits.
