Short answer: yes, for the things in your go-bag that must stay dry and that you won’t need to get at often. Documents, a change of clothes, and fire starters are perfect for it. Medications, batteries, and anything you’ll grab in the first five minutes are better left loose.
What vacuum sealing actually does for a go-bag
- Keeps out water. A sealed bag survives rain, a flooded basement, or a dunk in a creek. Paper won’t warp and ink won’t run.
- Stops mold and mildew. Less air means less moisture trapped inside, so clothes stay fresh for months.
- Saves space. Clothing compresses to a fraction of its size, which matters in a bag you might carry for miles.
- Keeps things organized. Each sealed pouch is one kit: documents, clothes, fire. You can see what’s inside at a glance.
Worth vacuum sealing
- Copies of important documents. ID, insurance cards, prescriptions list, and emergency contacts. These are the papers you need most after a flood or fire, and the ones water ruins first.
- A full change of clothes. Socks, underwear, a shirt, and a warm layer. Dry clothes after a soaking are a real comfort and a safety issue in cold weather.
- Fire-starting materials. Matches, tinder, and fire starters only work if they’re dry.
- Paper parts of your first-aid kit. Instruction cards and medical information. The supplies themselves are better kept in their own organized kit.
- A small cash reserve. Small bills, sealed flat, stay clean and dry. ATMs and card readers don’t work when the power is out.
Think twice before sealing
- Medications. They expire and need checking. Sealed away, they’re easy to forget until it’s too late to replace them. Some are also sensitive to heat.
- Batteries. Keep them loose and check them on a schedule. A battery that leaks or swells inside a sealed bag can damage everything around it.
- Anything you need in a hurry. Your flashlight, water, knife, and phone charger should come out in seconds, not after a fight with a plastic bag.
- Sharp or pointed items. They can puncture the bag, and a puncture lets the moisture right back in.
Make sealed bags easy to open
The biggest complaint about vacuum sealing is getting into the bag in the field. Three simple habits fix that:
- Cut a tear notch before sealing. Snip a small notch in the edge of the bag, above where the seal will be. You can rip it open by hand, no knife needed.
- Label the outside. Write what’s inside and the date with a permanent marker, or slip a label in before sealing so it shows through.
- Pack in small kits, not one big bag. Several small pouches mean you only open what you need, and everything else stays sealed and dry.
The real tradeoff: resealing
Once you open a sealed bag, you can’t reseal it without a machine, and you won’t have one in the field. So treat sealed items as “set it and check it twice a year.” Seal them at home, date them, and redo them during your regular kit review.
A good habit is to pair that review with the change to and from daylight saving time. Check ID and insurance copies for anything out of date, swap out clothes that no longer fit the season, and reseal.
Sealing protects a few papers. Keep the rest safe too.
A sealed pouch can only hold the handful of documents you’d need in an evacuation. Your full set of records, including deeds, titles, wills, and medical history, needs a home too. Family Ark stores them encrypted on your own phone or computer, with no cloud and no subscription. Use our Bug-Out Bag Document Checklist to decide which copies go in the sealed pouch.
And to keep the whole kit on track, SurvivalArk, coming soon from the makers of Family Ark, keeps a go-bag checklist for each person in your family and tracks expiration dates on the supplies you store. Join the waitlist to hear when it launches.
Frequently asked questions
Do I need a special vacuum sealer?
No. A standard kitchen vacuum sealer works fine. The bags matter more: choose thicker bags made for long-term storage, since thin ones puncture easily.
How long do sealed documents last?
Years, if the bag is stored somewhere cool and dark. Keep it out of hot cars and direct sunlight, which can weaken the plastic and fade the ink.
Should I laminate documents too?
For the papers you’ll actually handle in the field, like a contact list or map, laminating and then sealing is the most durable combination. Remember that official originals should not be laminated; seal copies instead.
Can I vacuum seal food and water?
Some foods, yes, but food storage has its own rules for shelf life and safety. Commercially packaged emergency food and sealed water are the simplest choice for a go-bag.
