Might as well just purchase bulk boxes, transfer noodles and cheese packet to a ziplock bag, and fill a 5 gal food grade bucket with them. Save one cooking directions for the lid. That keeps it all in easy to use portions.
BTW food-grade buckets can (or at least used to) be purchased for $1 at WM.
Go to the bakery. They are the buckets their frosting for cakes and cupcakes comes in.
There are round ones and rectangular. The rectangular are much larger and better for storing all kinds of things. Sometimes they go quickly. You need to catch them, usually, when their are people behind the counter.
