Sealing food in Mylar bags with oxygen absorbers is one of the best ways to store your emergency foods. A Mylar bag is a vapor barrier bag that blocks oxygen, moisture and light, the three big enemies of food storage. Think of it as a flexible metal can. Using a Mylar bag inside a bucket can add years to the storage life of your emergency supply.
Mylar bags come in many different sizes, thicknesses and styles but the most popular is just the plain open top bag that is sealed with heat.
The 7.5 mil Extreme bags we carry are the best option for vacuuming, or for storing things with edges like pasta for example.They are less prone to pinholes and can be stored just as they are on a shelf, whereas the thinner bags should be inside of another container to protect the bag. Obviously, even the thickest bag will not protect from rodents and it is still a good idea to use a plastic container or bucket of some sort.
Sealing Mylar bags is not difficult. If you own a Foodsaver or any other brand of vacuum sealer, you can use the seal bar on that to seal the bags. However this will not pull a vacuum as Mylar bags do not have the air channel grooves in them like a vacuum sealer bag does, but it works great as a heat sealer. Many folks get by quite well sealing Mylar bags with a regular household iron. If you would like to try this option, do a Google search or watch some videos on Youtube about sealing Mylar bags.
