Many preppers buy dry foods in No. 10 cans. They are excellent for long-term storage, especially for smaller families or individuals. But then we have the question: What do we do with the empty cans?
I've experimented with reusing them to store more dry foods. I packed the food in a clean can, added an oxygen absorber, put a piece of mylar on top large enough to form a lid, and then the plastic lid. I wrapped several rounds of duct tape to secure the lid and to (hopefully) make an air-proof seal. I did some a couple of months ago and the product has kept good, but this is not "long-term" by any means.
Then the other night I saw a youtube video by technician55 on his method of storing dry foods in 5 gallon buckets. He used another bucket with a mylar bag to form a round receptacle that fits much better into the 5 gallon bucket. He takes the bucket and inserts it into the mylar bag as far as it will go down. He then folds over the ends of the bottom and tapes them down, and then pulls the bucket out of the mylar bag. If this doesn't make sense, you can watch his video at https://www.youtube.com/watch?v=VZ1Cum6lkhs. He then puts his pre-formed mylar bag into another bucket and fills it.
I thought I'd try to make my own pre-formed mylar bag insert for an empty #10 can. Some of the PETE bottles that my neighbors save for me are rectangular gallon-size water bottles. One just barefy fits into a gallon mylar bag and I pushed it down as far as it would go. I folded the bottom flaps over and secured them with a single piece of tape. I was able to pull my plastic water bottle out of the mylar bag without any difficulty, so I'm not going to bother putting holes in the bottom like technician55 did. Then I put the pre-formed mylar bag into a #10 can and filled it with the instant potato flakes that I had packaged a couple months ago in another used #10 can. I was able to compress the flakes and get them all in. I don't have any oxygen absorbers on hand, so I didn't seal the bag up, but there's plenty of room for a seal using a hair iron. Fold the top corners over, and then put the plastic lid on.
I'm having difficulty uploading photos so I'll try again later.
I'm very pleased that #10 cans can be reused for long-term storage of dry foods.
If we had no winter, the spring would not be so pleasant; if we did not sometimes taste of adversity, prosperity would not be so welcome. Anne Bradstreet
And if men come unto me I will show unto them their weakness. I give unto men weakness that they may be humble; and my grace is sufficient for all men that humble themselves before me; for if they humble themselves before me, and have faith in me, then will I make weak things become strong unto them. Ether 12:27
Yea, all things which come of the earth, in the season therof, are made for the benefit and the use of man, both to please the eye and to gladden the heart; Yea, for food and for raiment, for taste and for smell, to strengthen the body and to enliven the soul. And it pleaseth God that he hath given all these things unto man; for unto this end were they made to be used, with judgment, not to excess, neither by extortion. D&C 59:18-20
