I came across this blog post while perusing Pinterest recently. I found that it condensed all the information that I found on mylar bag food storage when I was researching dozens of blogs and websites.  So as you start to purchase your emergency food supplies and work through how you want to store your supply here is a great article on Mylar bags to save you some time in the research department.
