I've always frozen fish by putting them in a container and covering them with water. The water freezes completely around the fish with no freezer burn. My grandmother once took washed out milk cartons (the paper-waxed kind) put the fish in, completely covered them and folded the top down. We could have fish anytime later by just thawing them out in the refrigerator. I get my deer processed wrapped in 1-2# freezer wrapped paper. I just put the meat already wrapped in a vacuum sealed bag for extra protection and it lasts a long time. So far my oldest was 3 years. I buy bacon in 10# boxes at Sam's. It has about 20 layers of bacon with paper in between. I put two layers in a vaccum seal bag for about 1# packages. It is a lot less expensive than regular bacon, tastes great, and is mainly used by restaurants. If we have frozen or pre-frozen home grown veggies, I package in a vacuum seal bag. I have heard of people vacuum sealing entire guns using the wide rolls of vacuum wrap paper. Not a bad idea, if you want to store one long term. Ammo can also be done that way in packages for long term storage. Water proof matches, fire starting materials, spare clothing on backpacking or camping trips to keep dry in case you fall in a body of water. Lots of uses.
