The last time I bought 25 pound sacks of beans, they bags they came in were triple thick - paper inside, plastic in the middle and paper on the outside. If I were to buy 25 pound sacks of beans, oatmeal, etc and put them in 48 quart ice chests...just add the silica gel or the stuff to dry the water out of the air...then seal the lid with aquarium silicon - maybe 2 or 3 beads - will that be enough processing of the food to give it the 10 year or more shelf life that that kind of stuff is supposed to have?
