I know this isn’t a section on vacuum sealing, but it is a great Prepper tool, not just for food items but for storing ‘stuff’ as well. As you pointed out, our BOB has our clothes vacuumed sealed to reduce space. Some disinfectant soaps, medical supplies and more. We like the idea of water proofing what we can and the space reduction. When I vacuum seal a firearm it is put away safely & securely. It is not a firearm I plan to use anytime soon. Having said that, easy tear open and cheap & easy to reseal. It takes 4-minutes out of your day to vacuum seal after cleaning (more on that below). Oh, and unless you notice that the vacuum bag is leaking (no longer tight around the interior components) the desiccants are good to go until after you open the package (also good desiccants can be reused after heating). As Matthew correctly pointed out, your home/personal protection firearm should be easily accessible, but secure from kids who may be up and around in the night. Safe storage is inversely proportional to accessibility for most people. A semi-expensive digital safe, securely mounted to a wall stud, by your bed and in your most commonly occupied room, offers a potential solution for both. But I digress, this question & forum is about Prepping & storage: I’m 67 years old, a good Prepper with 22 years military service. I’m been flooded, lived through several hurricanes (we live on the coast) and had a very larger tree fall on our home making everything inside a miserable mess. As a Prepper, I prep for the worse case scenario (that I can afford) and hope for the best. Everything I have water sealed remained dry. Transporting goods in a ferocious rain to bugout can leave a person & goods soggy indeed. Never know, it might be good to have more items watertight, even for the short term, just in case.
