A few years ago I purchased a skid of unused 1 gal. paint cans. They are great for storing dry goods. (rice, dried beans, etc.)
I put a golf ball sized chunk of dry ice in the bottom and fill with the dry food item. Loosely place the lid on. Wait until the bottom of the can warms up. Then seal the lid on.
The dry ice makes the bottom of the can cold. As it sublimates it fills the can with CO2 driving out all other gasses. When the can warms up, the ice is gone and all gasses have been replaced. The sealed food will keep for years.
This works well and saves a lot of money in the long run. I can buy a 50lb bag of dry beans, seal in cans, and only have one open at a time. The open can can be resealed and with the lid on bugs & mice can’t get into it.

That sounds like a great way to store those bulk items!
