TL;DR -- Food storage supplies overview
Building a 90-day food storage system requires two categories of supplies: container supplies (to seal and store the food you buy) and preservation supplies (to convert garden produce and bulk purchases into stored food). The container supplies are the priority for the archive layer. The preservation supplies become important as the garden production layer develops. This article covers both categories with exact specifications, cost ranges, and where to source each item.
The most common equipment mistake I see in food storage builds is buying supplies without understanding the system they support. Someone buys a vacuum sealer because they think it's the primary sealing tool (it's not -- it doesn't work on 5-gallon bags, and oxygen absorbers do the actual preservation work). Or they buy small 1-gallon mylar bags because packing 5-gallon quantities seems overwhelming, and end up with twice the work and inferior seals. This article specifies what to buy and why, so you buy the right things once.

Category 1: Container supplies for dry staple storage
| Item | Specification | Cost | Where to buy |
|---|---|---|---|
| Food-grade 5-gallon buckets | HDPE #2, food-contact certified, natural or white | $3--$6 each | Home Depot, Lowes, Uline, free from bakeries |
| Mylar bags, 5-gallon (primary) | 5-mil thickness, 20"x30", minimum 1-mil (5-mil preferred) | $1.25--$2 each in bulk | Amazon (Wallaby brand), LDS Store, Diecutmylar |
| Mylar bags, 1-gallon | 5-mil, for smaller portioning | $0.80--$1.50 each in bulk | Amazon, LDS Store |
| Oxygen absorbers, 2,500cc | For 5-gallon bags of grain/legumes | $0.30--$0.60 each | Amazon (Wallaby brand), LDS Store |
| Oxygen absorbers, 300cc | For quart mason jars and 1-gallon bags | $0.12--$0.25 each | Amazon |
| Gamma seal lids | For active-use rotation buckets (re-sealable) | $7--$12 each | Amazon, Walmart |
| Standard pry-off bucket lids | For archive layer buckets | $1--$2 each | From bucket supplier |
| Rubber mallet | For seating standard bucket lids | $10--$15 | Hardware store |
| Lid wrench / bucket opener | For opening sealed archive buckets | $5--$10 | Hardware store, Amazon |
| Food-grade labels / permanent marker | For dating and identifying all containers | $3--$8 | Office supply |
Minimum required to pack 20 buckets (family of four base supply):
- 20 food-grade buckets: $60--$120 (or zero from bakery source)
- 20 five-gallon mylar bags: $25--$40
- 50 oxygen absorbers (2,500cc): $18--$30
- 14 standard lids + 6 gamma lids: $20--$86
- Total containers: $123--$276
Category 2: Sealing equipment
Option A: Standard household iron (recommended for most users) Any household iron with a flat soleplate, set to cotton/wool provides sufficient heat to seal mylar bag at the standard 1-inch seal width. Works reliably for 5-gallon bags. Cost: $0 if you own one; $20--$40 for a basic model if not.
Option B: Flat iron (hair straightener) A flat iron provides a narrower sealing surface with more precise heat control. Works well for 1-gallon bags. Less ideal for 5-gallon bag cross-sealing due to the shorter sealing width -- requires multiple overlapping passes. Cost: $15--$30.
Option C: Commercial impulse sealer (upgrade) A commercial impulse sealer provides a clean, consistent seal across the full bag width in a single operation. More reliable than an iron for high-volume packing sessions. 8-inch or 12-inch models appropriate for 5-gallon bags. Cost: $50--$120.
The seal quality test: Regardless of which sealing method you use, test the seal 24 hours after packing. A properly sealed bucket will be noticeably hard (vacuum-tight as oxygen absorbers complete their work). If still soft, the seal is incomplete -- re-seal the same area before storing.
Category 3: Preservation equipment -- dehydration
| Item | Specification | Cost | Notes |
|---|---|---|---|
| Basic round dehydrator | Nesco FD-75, Presto 06300 | $60--$80 | Best beginner dehydrator; adequate for herbs, fruit, vegetables |
| Excalibur square dehydrator | 5-tray or 9-tray, adjustable thermostat | $200--$400 | Superior airflow, higher volume, more consistent results; preferred for regular use |
| Fine mesh dehydrator screens | Fits round dehydrators | $5--$10/set | For small foods (herbs, small berries) that fall through standard trays |
| Meat thermometer | Instant-read, accurate to ±1°F | $15--$35 | Required for verifying meat reaches 165°F during jerky production |
| Mandoline slicer | For uniform vegetable slices | $20--$35 | Uniform thickness = uniform dehydration time |
Which dehydrator to buy: For a beginner building toward home food production, start with a Nesco or Presto round dehydrator. For a household with active garden production that will run the dehydrator 20+ hours per month during peak season, invest in a 9-tray Excalibur from the outset. The Excalibur's square trays and rear-mounted fan provide dramatically more consistent drying across all tray levels compared to round models with top-mounted fans.
Category 4: Preservation equipment -- canning
| Item | Specification | Cost | Notes |
|---|---|---|---|
| Large stock pot with rack | 16--21 quart; includes jar rack | $25--$45 | Water bath canning for high-acid foods |
| Pressure canner | Presto 23-qt or All American 21½-qt | $90--$200 | Required for all low-acid foods (vegetables, meat, beans) |
| Mason jars, wide mouth | Ball or Kerr, quart size (case of 12) | $12--$18 | The universal canning jar; buy wide mouth for easier packing |
| Mason jars, regular mouth | Ball or Kerr, pint size (case of 12) | $10--$15 | For jams, pickles, and high-acid foods |
| Canning lids (wide mouth) | Ball, 3-pack of 12 = 36 lids | $4--$6 per box of 12 | New lids every use; bands can be reused |
| Jar lifter | Standard canning jar lifter | $8--$12 | Critical safety tool -- avoid direct canning jar contact |
| Canning funnel | Wide and regular mouth | $8--$10 | Prevents rim contamination during filling |
| Magnetic lid wand | Picks up lids from hot water | $5--$8 | Small convenience with real utility |
| Headspace tool / bubble remover | Clear plastic, dual-purpose | $6--$8 | Measures headspace accurately |
| Ball Complete Book of Home Preserving | 2006 or later edition | $20 | Essential tested recipe source |
| Pressure gauge testing | Annual dial gauge test at county extension | Free or low cost | Dial gauge pressure canners require annual accuracy verification |
Water bath versus pressure canner -- do I need both? Start with the water bath setup (stock pot + rack + jars). This handles tomatoes, pickles, and jams. Add the pressure canner in Year 2 when you are ready for vegetables, meat, and beans. You do not need both from day one unless you have immediate high-acid and low-acid preservation needs simultaneously.

What to skip: equipment that doesn't earn its cost
Vacuum sealer for archive layer: A vacuum sealer cannot seal 5-gallon mylar bags -- it is designed for vacuum bags, not mylar. For the archive layer, heat sealing + oxygen absorbers provides better results. A vacuum sealer is useful for mason jar sealing (with the jar attachment) and for extending the freshness of opened items in the rotation layer -- but it is not a primary long-term storage tool.
Commercial freeze dryer (for most households): A home freeze dryer ($3,000--$5,500 new) produces results inferior in quality to industrial freeze-drying due to less precise temperature and vacuum control. The cost per pound of home-dried food is higher than commercial freeze-dried, and the shelf life is shorter (5--10 years vs. 25 years for factory processed). Buying factory-sealed freeze-dried cans from My Patriot Supply, Mountain House, or Thrive Life is more cost-effective for most households than producing freeze-dried food at home.
Branded emergency food buckets: Pre-assembled 72-hour or 30-day food buckets from survival suppliers are significantly more expensive per calorie than building the equivalent from bulk purchased components. The convenience factor is real -- they are ready to grab in an emergency. But they cost 10--20x more per calorie than the DIY equivalent.
Priority purchase sequence: what to buy first

| 3 (Month 1--2) | Basic dehydrator | Start drying garden herbs and produce | $60--$80 |
| 4 (Month 3--4) | Water bath canning pot + mason jars + Ball book | Add high-acid preservation | $45--$70 |
| 5 (Month 6--12) | Pressure canner (Presto 23-qt) | Add low-acid preservation capability | $90--$130 |
| 6 (Year 2) | Upgrade dehydrator to Excalibur if volume warrants | Improve throughput during harvest | $200--$350 |

FAQ
Can I use a FoodSaver vacuum sealer for mylar bag sealing?
A FoodSaver sealer can seal 1-gallon mylar bags if the bag is small enough to fit within the machine's sealing jaw width. It cannot seal 5-gallon bags, which are too wide for the sealing mechanism. The FoodSaver jar attachment is useful for extension sealing mason jars -- placing the sealing attachment over the lid and running the vacuum cycle creates a sealed jar without a heat seal. This is not equivalent to the mylar + oxygen absorber system for long-term 25-year archive storage, but it extends freshness for 1--5 years on items in regular use.
How many oxygen absorbers do I need per 5-gallon bucket?
For a 5-gallon mylar bag packed with dry grains or legumes: 2,000--3,500cc total. You can achieve this with: one 2,500cc absorber (single, available from most suppliers), two 1,500cc absorbers, or two 2,000cc absorbers (provides extra margin). For high-density, fine-ground products like flour or powdered milk, use the higher end of the range (3,000--3,500cc) because fine particles have more surface area and slightly more residual oxygen than whole grains. Undersizing is the most common oxygen absorber mistake -- when in doubt, use more rather than fewer.
Are bakery buckets safe for food storage?
Yes. Grocery store and restaurant bakeries receive frosting, shortening, and food ingredients in food-grade HDPE #2 buckets that are identical in food-safety certification to purchased food-grade buckets. They have been in direct contact with food in their prior use. Rinse with soapy water, rinse well, and allow to thoroughly air-dry before use. The residual frosting smell will not transfer to your stored food. These are free, food-safe, and plentiful at most grocery store bakeries. Call ahead and ask how many they typically discard per week -- many will save them for regular pickup.
The right equipment, once
The equipment list for a 90-day food storage system is short and inexpensive: buckets, mylar bags, oxygen absorbers, and a household iron. That's the archive layer. Add a dehydrator for herb and vegetable preservation. Add a pressure canner in Year 2.
Total first-year equipment investment: under $200 above the food cost. The equipment pays for itself on the first batch of home-dried herbs and home-canned tomatoes.
Buy the right equipment for the right application. Follow the purchase sequence: containers before food. Pack and seal before worrying about upgrades.
