Sealing Mylar Bags For Food Storage

If you have food storage you know that heat, light and air are your food supplies worst enemy. You can seal dry goods in jars and store them that way but then you still have light. The best way to store foods for long term is in mylar bags with oxygen absorbers. Once the bag is sealed with the oxygen absorber inside , the absorber will consume the oxygen that is in the bag and your bag will end up looking as if it had been shrink wrapped. This is really the best method because you eliminate light with the mylar and air with the oxygen absorber so then you only have to worry about storing the bags in a cool place.  I like to seal my bags and then I put them inside those plastic totes with the snap on lids.

This protects the bags from any possible bumps that may puncture the bag. After you have sealed your bags and before putting them away in the totes wait at least 24 hours to make sure they bag has shrunk around the food. If it doesn’t end up looking shrink wrapped you will need to repackage and seal again to be sure there is no air left in the bag. If you are storing in five gallon buckets then you don’t have to worry about the totes but you still need to make sure the bag shrunk around the food tightly before sealing the bucket for storage.  Delta69alpha has a great video showing how to seal your bags using an iron.
