Sealed ammo can or mylar bags put into plastic bins to keep moist air away from them is all you need. I have nearly half of my ammo in ammo cans and the rest in rubber Maid bins except for the amount I keep out in my ammo locker for ready use. Just don't let it get overly hot or freezing cold and they will last longer than you will.
