Mylar bags are the best long-term storage method for dry foods like rice, beans, and flour. When done correctly, some foods can even last over 25 years!
As one man aptly said in a survival forum, Mylar is
Every prepper’s favorite kind of plastic. I know I have been trying (unsuccessfully) to get my wife to dress in it for years.
The trade name for Mylar is biaxially-oriented polyethylene terephthalate. It was originally produced in the 1950s and used for insulation, solar filters, blueprints, and even kites.
*For Mylar bags to work, most foods need to be stored with oxygen absorbers. However, some foods should not be stored with oxygen absorbers.
– Open Mylar bags and put each in a bucket/container – Line up the containers – Make sure your sealer has a cord long enough to reach the buckets
– Using a scoop or a funnel, fill up the Mylar bags with food. You’ll need to give the bags a good shake to ensure the food particles are settled (which means more food per bag and less air).
– Fill the bags to about 4-5 inches from the top. Make sure you don’t overfill the bag, or it will be tough to seal. – Label the bags and container with the contents plus the date.
