As far as foodstuffs, I do smaller quantity packaging. I think 40 pounds of a gotta grind yourself wheat or rice or such in a bag in a bucket is too much open at a time. For long term storage you get rid of the 3 things that spoil. Light, moisture and oxygen.
I do foodstuffs in a steel #10 can with O2 absorber inside. Latter Day Saints cannery. Available to you (whatever religion or none) and sometimes near you. Only one in NC. See Below.
As far as other type stuff to be able to load up and move out quick, I load up the bucket with a varied supplies, vacuum sealed foodstuffs, cans, clothing and other necessities. Its also good storage methodology for long term. IMHO again.
Each bucket has at least two rolls of TP. One to use, one to trade. That will be soft gold (like pads or plugs) when bucket needs opened. I like it so I can go a day or 2 or 5 on one bucket with everything I could need but water. Unpack the bucket to gas and seal it.
I line the bucket with a mylar bag. Put about a pound of dry ice in the bottom wrapped in a towel or 2. Repack original bucket stock. Towels ( in each bucket, around CO2, are always dry off, trade, blanket or other use stuff. That CO2 will drive out all other gases, primarily oxygen and moisture.
As thats melting repack the bucket in the order you already tested so you know it will fit. When the bucket is full and CO2 block melting, heat seal up the bag but not completely. Be quick on the refill because the dry ice is melting and you need melting after you're done repacking. Seal all but a small exit so the CO2 builds pressure. Clip that hole but not tight enough to blow the bag. When pressured up, open so the excess is going out a small exit. Collapse the bag so the excess gas leaves and clip again. You may need several squeezes to let the air and excess CO2 out and have only CO2 in the bag.
Of course there are a couple O2 absorbers loose in the bucket in case you missed any, with a moisture absorber also. When thats done, seal the bag and seal the bucket. Be sure you have at least 4 lists for each bucket. One inside the mylar bag, one outside the mylar bag inside the bucket and one attached to the bucket on the outside and one on the master list of all your supplies. Number the bucket (to master list) and some spray paint a line on the outside of the bucket. It helps to get a general idea of whats inside by using various colors painted on it.
Keep the buckets in a cool, dark, dry place as much as possible.
Yeah, might be a bit long, but I have a tendency to ramble. Ask anyone around here.
