Mylar bags combined with oxygen absorbers stored in a rigid container have been shown to be the ideal way to store dehydrated goods for long-term storage. Mylar bags protect your food investment from the effects of oxygen, moisture contamination, and light penetration. These Mylar bags are 4.5 mils, and provides excellent long-term storage of dehydrated foods and has an FDA approved sealant layer. Mylar®, a Polyester bag is ideal for a broad array of applications in the electrical, electronics, magnetic media, industrial specialty, imaging and graphics, and packaging markets. These Mylar bags can be heat sealed with a standard clothes iron on the wool setting or a hair straightener. Add your dehydrated food to the Mylar bag, place appropriate number of oxygen absorber on top (2000cc-2500cc), and push out as much residual air as possible before sealing the bag. All Mylar bags should be placed in a rigid container such as a plastic bucket to protect the integrity of the bag as well as to avoid rodents and bug infestation. Unused oxygen absorbers can be resealed in their original bag, placed in a mason jar, or heat sealed in a Mylar bag.
