Oxy packs are not effective in plastic....the plastic is actually porous.....read the LDS church's website if you're interested in finding out how to 'treat' wheat for long term storage using dry ice. A lot of how you choose to 'store' your commodities depends on how long you intend to store it...are you going to use it in a year, five years, are you rotating what you have? The old adage 'store what you eat, and eat what you store' is really important when you consider the new counsel from the brethren to have a three month supply of food on hand that your family normaly eats and then work on your 'years supply' of longer shelf life items like wheat and beans. Do a little research and I'm sure you will find the right answer for your individual situation. Good luck!

Good to know oxy packs don't work in plastic. I'm thinking more along the lines of 3-5 yrs. I'm planning on rotating and wanted to buy some 20 lb bags and stock up on noodles too but I know even if I use them a ton with only two of us to feed we can't use a all of it and don't want it to spoil.

Take advantage of using a Foodsaver, or take a turn borrowing the mylar sealer or other sealer that your Stake has.  I own both a Foodsaver and a Mylar bag sealer. (The oxy packets work well in those.) Also, DON'T pay for the buckets. You can obtain food grade buckets for FREE from Costco or grocery store bakeries just for the asking.
