Storing food for months or years sounds simple — you just put it in a container and wait. But the wrong container lets in oxygen, moisture, and light, turning your emergency stash into a science experiment you do not want to open. This guide cuts through the options — from heavy-duty Mylar bags to glass jars and food-grade buckets — so you know which container actually keeps your rice, beans, and freeze-dried meals edible for the long haul.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The three materials to know are Mylar bags (flexible pouches with an aluminum layer that block light and air), glass jars, and food-grade plastic buckets. Each fits a different need. This article is your practical guide to the best containers for long term food storage, whether you are building a year’s supply or just better organizing your pantry.
Our Picks at a Glance
How To Choose The Best Containers For Long Term Food Storage
Your long-term food storage will fail if oxygen, moisture, or light get in. A container must block all three for years. Here is what matters most when you choose one.
Material: Mylar vs. Glass vs. Plastic
Mylar bags are the top choice for blocking oxygen and light because they contain a layer of aluminum foil. They are lightweight, easy to store, and can be heat-sealed for an airtight barrier. Glass jars (like mason jars) let you see your food and are reusable, but they are heavy and can break. Food-grade plastic buckets are ideal for very large amounts — think 5 gallons of rice or wheat — but they need an oxygen-absorber-compatible lid to be truly airtight.
Thickness (Mils)
Mylar bag thickness is measured in mils (thousandths of an inch). A bag that is 5 mil thick per side is good for most grains and pastas. A 7.5 or 15 mil bag stands up to sharp edges in freeze-dried foods and resists punctures better. Thicker bags cost more but give you more confidence for decade-long storage.
Oxygen Absorbers
An oxygen absorber packet removes the oxygen inside a sealed container, which stops insects from hatching and prevents food from spoiling. You pair the packet’s capacity (measured in cc) with the bag size — a 1-quart bag needs about 200-300cc, a 1-gallon bag needs about 400cc, and a 5-gallon bag needs 1000-2500cc. Without oxygen absorbers, even the best bag cannot give you long-term shelf life.
Size and Quantity
Think about what you store. Quart-sized bags are handy for single-ingredient portions or freeze-dried meal packs. Gallon-sized bags suit rice, beans, and pasta. A 5-gallon bag is for bulk staples like wheat berries and sugar. Many kits come with a mix of sizes, which is a flexible way to start.

In-Depth Reviews
1. Wallaby 50 Count 1-Quart Gusset Mylar Bags with Labels
Our pick — over 4.5★ from 800+ verified ratings; the strongest balance of quality and price.
The quart-sized Mylar bag that has owners coming back for a second box.
The Wallaby 1-Quart bags earn the top spot because they combine a practical quart size with a 6 mil thickness per side (12 mil total) that resists punctures better than standard bags. That thickness means sharp freeze-dried items are less likely to poke through. The 1-quart size fits tea, instant coffee, freeze-dried single meals, or cash and matches in an emergency kit. Unlike the deeper 5-gallon bags in this guide, these stand up on their own thanks to the gusseted base — you can fill them without propping them open.
The kit includes 50 bags and 50 sticker labels, so you can write the content and date right on the bag. The bags come with a zip seal for short-term use, but for long-term storage you heat-seal above the zipper. The crowd favorite feature here is the overall quality — the thing owners praise most is the build quality, with over 80 buyers calling them out as solid and reliable. Buyers report that the 2.5-gallon Wallaby bags hold 10 lbs of wheat berries with a 1000cc oxygen absorber and the 15 mil thickness prevents punctures, and the same sturdy build applies to these quart bags.
What wins people over
- Thick enough to resist punctures from sharp food edges
- Comes with 50 labels and a resealable zipper for short-term use
- Gusseted base lets them stand upright for easy filling
The honest caveat
- Some recent batches feel slightly thinner, so inspect before heat-sealing
- Quart size is too small for bulk grains like a full bag of rice
Reach for these when: you want the best overall balance of thickness, value, and convenience for small portions — a near-universal choice for daily pantry use and emergency prep alike.
Look elsewhere if: you need a bulk 5-gallon size; Wallaby does make larger bags, but this specific pack is for quart-only storage.
2. DEIAO 15 Mil 5 Gallon Mylar Bags with 2500cc Oxygen Absorbers (55 Pack)
A 55-piece variety pack that covers every size you need in one box.
This is the most versatile set for anyone building a long-term food supply from scratch. You get five 5-gallon bags (15 mil thick), twenty 1-gallon bags (9.45 mil), and thirty 1-quart bags (9.45 mil) — plus 100 colorful labels, 5 sealing clips, and a pack of 2500cc oxygen absorbers. The 5-gallon bags are noticeably thicker than most competitor bulk bags — at 15 mil versus the ShieldPro packs’ 5 mil, which buys you serious puncture resistance for sharp grains like wheat berries or bone-in freeze-dried items.
The bags have a zipper top for short-term access, and above it you heat-seal for long-term storage. Build quality is the most-praised aspect, mentioned by over 30 buyers, and thickness is the second most-discussed positive attribute. One owner summed it up: “these are high quality, heavy mil stand up bags. I heat sealed them all with a Revlon hair straightener with zero problems.” The honest trade-off: the 5-gallon bags are tall and slender, so they do not sit perfectly in standard 5-gallon buckets, and the minimal Mylar above the zipper can make heat-sealing tricky if you are not careful.
Why it stands out
- Three sizes cover everything from bulk wheat to single tea servings
- 15 mil thickness on the 5-gallon bags is among the thickest you will find
- Oxygen absorbers and labels included — ready to work immediately
Know before you buy
- 5-gallon bags do not fit perfectly into round buckets
- Oxygen absorbers lack a color indicator dot to show they are still viable
Pick this if: you want a single purchase that gives you bags for both bulk and small-quantity storage — the best “start here” bundle on the list.
Think twice if: you plan to load your 5-gallon bags inside standard buckets; the tall shape causes bunching.
3. PackFreshUSA Quart (8″ x 12″) AirTight Mylar Bags with 300cc Oxygen Absorbers (50 Pack)
The bag that preppers and pros trust — with colored-indicator absorbers that prove they work.
PackFreshUSA stands out with thoughtful design details. Each bag has tear notches so opening is easy, and the 7.5 mil thickness per side is a touch above the Wallaby quart bags — an advantage if you are storing freeze-dried items with sharp corners. The oxygen absorbers come pre-packed in packs of 10 inside a vacuum-sealed pouch, and each pack includes a pink oxygen indicator so you can confirm at a glance the absorbers are still active. This is a 0.25-gallon capacity (the smallest in this guide), which is best for individual servings or small ingredient portions.
Bags seal easily with a standard FoodSaver on seal-only mode, and the design leaves extra room above the fill line for sealing without burning the Mylar — a problem reported on some of the DEIAO 5-gallon bags. A few owners note that the bags are thin enough to be see-through (normal for Mylar, the included instructions explain this) and that one or two bags have failed during vacuum-sealing when a sharp food edge pokes through during compression. It is a rare issue, but worth knowing if you pack spiky freeze-dried items.
What we like
- Oxygen absorber packs include a pink indicator to verify freshness
- Tear notches for clean opening without scissors
- Extra Mylar above the zip makes heat-sealing safer
The small trade-off
- At 0.25 gallons, capacity is limited compared to the gallon and 5-gallon options
- Bags are a bit see-through; if you store in direct light, use an outer bucket
Best for: preppers who want a complete, simple to use system in quart size — thoughtful packaging and verified absorbers make this a reliable choice.
Not ideal if: you need bulk storage for 5-gallon buckets; stick with the 5-gallon options for large quantities.
4. Wallaby 50 Count 1-Gallon Mylar Bags with Labels (10 Mil Total Thickness)
The Wallaby 1-gallon bag, now in a bulk 50-pack that fits freeze-dried meals and rice perfectly.
If you liked the Wallaby quart bags above but need the larger 1-gallon size, this is the same reliable build in a bigger format. Each bag measures 5 mil on each side (10 mil total), which is slightly thinner than the Wallaby quart bags but still standard for this size. The 1-gallon capacity is a practical middle ground: it holds about 5 lbs of rice or a full load of freeze-dried meal components without being as unwieldy as a 5-gallon bag. As buyers put it, these bags “keep heat sealer on a little longer than the thinner ones” for a good seal, and they work well in a chamber vacuum sealer.
The bundle includes 50 sticker labels, so organization is straightforward. Owners praise the food protection — that is the second most-discussed positive attribute, behind quality. One area where feedback is split is the sealing process: some buyers needed to hit the seal button 5 or 6 times to get a reliable seal. That is not a defect in the bags themselves — just a note that your heat sealer needs to be hot enough and held long enough. For the value (50 bags plus labels), this is a solid buy for medium-scale storage.
The highlights
- Good size for 5 lb portions of grains, beans, or pasta
- Compatible with chamber vacuum sealers — uncommon for Mylar bags
- 50 labels included for clear dating and identification
Watch out for
- Sealing requires a longer hold time to get a full bond
- Some owners mention mixed durability — inspect the bag surface before use
Grab this for: building a medium-term pantry with labeled, stackable 1-gallon portions — especially if you use a chamber sealer.
skip it if: you prefer a ziplock top for convenience; these are heat-seal only, so once sealed, you cut them open.
5. SHXWELL 30-Pack 2-Gallon Mylar Bags (15 Mil Extra Thick) with 400cc Oxygen Absorbers
The 2-gallon Mylar bag that tested thickest among five competing brands.
SHXWELL offers a unique size: 2-gallon bags that split the difference between a 1-gallon and a full 5-gallon load. Each bag is 15 mil total thickness (7.5 mil per side), which makes it one of the densest pouches on this list — buyers who tested five brands side-by-side called these the thickest and most durable. The three-layer construction (PET, aluminum foil, and PE) explains the feel. The bags have a resealable zipper for daily use, but you heat-seal above it for long-term storage.
Each kit includes 30 bags plus 60 individually-wrapped 400cc oxygen absorbers (packed in 10-packs inside a vacuum-sealed pouch). The bags stand upright on their own, making filling easy — a large canning jar funnel helps. Quality is the clear winner here: 76 owners call it out as the standout feature, and 37 mention durability as a top reason to buy. The zipper alone is not enough for an airtight seal (slight leaks happen), but heat-sealing locks it down. Think of the zipper as a convenience feature for short-term access before you commit to the permanent seal.
Why it impresses
- Thickest 2-gallon Mylar bag tested — excellent puncture resistance
- Oxygen absorbers pre-packed in sealed 10-packs with no wasted product
- Zipper + heat seal gives you short-term and long-term options
The honest limitation
- Zipper alone is not fully airtight — must heat seal for long-term storage
- 2-gallon size is less common; may not fit standard bucket organizers
Best fit: the prepper who wants maximum bag strength without committing to a full 5-gallon bag — ideal for 15-20 lb batches of grains.
Not your bag if: you need a standard 1-gallon or 5-gallon size that fits neatly into existing bucket systems.
6. Anwoi Wide Mouth Mason Jars 64 oz (3-Pack)
Glass jars with a clamp-down seal that double as your prettiest pantry organizers.
Not everything needs to go into Mylar. For items you use regularly — flour, sugar, oats, pasta — glass jars keep food visible and accessible while blocking air. These Anwoi 64 oz jars (half-gallon each) come in a 3-pack with a hinged lid that has two sealing layers: a rubber gasket and a metal clamp. Customers note that the seal is tight enough to hold liquid without leaks when tipped. The wide mouth (3.74 inches wide) means you can reach inside to clean or scoop without a funnel.
The jars are BPA-free, food-grade glass, and they are dishwasher-safe (remove the rubber gasket first). Quality is the overwhelming praise here — 87 buyers rank it as the top feature. The second most-discussed aspect is storage capacity: at 64 oz each, three jars hold a combined 192 oz, which is enough for a large bag of flour and a bag of sugar. Size and appearance also score well. The honest trade-off is the lid seal: some owners find the clamp tricky to close fully, and the glass can crack if you pour in boiling water. These are not for canning with boiling water — use warm liquids only.
What works
- See-through design lets you check food levels at a glance
- Wide mouth for easy filling and cleaning
- Rubber gasket seal is leak-resistant when clamped correctly
What to know
- Do not use boiling water — can cause glass to crack
- Clamp can be stiff; not all owners achieve a perfect seal on first try
Grab these for: daily-use pantry staples where visibility and easy access matter more than 25-year shelf life.
Pass on these if: you need long-term, oxygen-free storage; glass jars are not ideal for decades of rice storage without an additional oxygen barrier.
7. EconoHome 5-Gallon White Bucket Pail Container with Lid (6-Pack)
Six food-grade 5-gallon buckets with metal handles — built for the prepper who buys in bulk.
When you need to store 30 gallons of rice, beans, or water, a thick plastic bucket is the practical answer. These EconoHome buckets are rated at approximately 90 mil wall thickness — far thicker than a standard hardware-store bucket — and they are made from BPA-free, food-grade plastic. The lids snap on with a tight seal, and the metal handles are wrapped in plastic grips for comfortable carrying. At 5 gallons each, a six-pack holds about 240 lbs of dry grains, making this the highest-capacity option in the guide.
Owners consistently praise the quality and durability — those are the top two most-discussed positive aspects. The buckets are tall enough to hold standard water filter cartridges, which is a nice bonus for emergency prep. The area where feedback is honest is the lid: owners describe the fit as “aggressive” — once fully engaged, the lid can be hard to remove. Some buyers had trouble getting a full seal, and the lid usability gets the most negative comments. That is common with buckets this thick; the seal is excellent once locked, but you need to apply pressure evenly. The buckets stack neatly, saving floor space in a garage or basement.
Why these work
- Heavy-duty construction with ~90 mil walls — very durable
- Metal handles make carrying 40+ lbs easier than plastic bail handles
- Stackable design for space-efficient bulk storage
The honest struggle
- Lids are very hard to remove once seated — plan for that
- Not all lids seal perfectly on every bucket; inspect before long-term use
Best for: anyone storing very large quantities of dry staples or water — if you have a 50-lb bag of rice, this is the container for it.
Not ideal for: small kitchens or daily access; these are heavy and the lids are not convenient for frequent opening.
8. ShieldPro 5-Gallon Mylar Bags 5 Mil + Oxygen Absorbers (10-Pack)
A straight-to-the-point 5-gallon bag kit for standard bucket operations.
ShieldPro has been making Mylar storage solutions since 2010, and this 10-pack of 5-gallon bags (5 mil thick) is built to fit inside a standard 5-gallon bucket. The bags are heat-sealable only (no zipper), and the kit includes either 10 x 2000cc oxygen absorbers or 20 x 1000cc absorbers — enough for the whole set. The bags are deep enough to hold 35 lbs of food and have a 5-layer construction that the company says offers greater barrier protection than 4.3 mil bags.
Quality and durability are the most-praised points — over 50 owners mention the build quality is top-notch. The bags seal well with a hair straightener or clothes iron, and the 8 inches of material above the fill line leaves room for a strong seal. The area with mixed feedback is the oxygen absorbers: some reviewers point out the 2000cc absorbers did not work in their batch. ShieldPro recommends testing one bag before committing all your food to a full run. The bags are slightly small for a 5-gallon bucket — they do not fold over the rim easily, so you need one hand to hold the bag open while filling.
The strengths
- Proven 5-layer Mylar construction for oxygen and moisture barrier
- Deep bags hold full 35 lb loads in a 5-gallon bucket
- Company has a long track record in the prepper community
Areas to check
- Oxygen absorber quality is inconsistent — test one bag first
- Bags arrive folded; may need to be shaken out before use
Choose this for: a straightforward, bucket-sized Mylar liner with a proven brand — good for grain storage if you verify the absorbers.
Another option: the ShieldPro Genuine Mylar pack (product 9 below) has better-reviewed oxygen absorbers for a similar price.
9. ShieldPro Genuine Mylar Aluminum Foil Bags with 2000cc Oxyfree Oxygen Absorbers (10-Pack)
The ShieldPro 5-gallon kit where the oxygen absorbers actually get consistent praise.
This ShieldPro variant addresses the biggest hesitation about the standard ShieldPro pack (product 8): the oxygen absorbers. Here, the 2000cc Oxyfree absorbers arrive individually vacuum-sealed with a pink oxygen indicator that turns color if the absorber has been exposed. Owners confirm the absorbers “were soft and powdery (good)” and “sealed a pint jar in under 15 mins” — concrete signs they are working. The bags themselves are identical in construction: 5 mil thick, genuine Mylar, 5-layer barrier, heat-sealable, and sized for a 5-gallon bucket.
The kit contains 10 bags and 10 absorbers (or 20 x 1000cc, depending on the batch). The BPA-free and PFAS-free claim matches the other ShieldPro listing. The top takeaway from owners is quality (40 mentions) and durability (22 mentions). The only hiccup some experienced was receiving 9 bags instead of 10 — a fulfillment issue rather than a product flaw. The bags seal easily with a hair straightener, and the honest feedback is that these are “very heavy duty and good quality.” If you want the ShieldPro name with less guesswork about the absorbers, this is the version to order.
The advantages
- Oxygen absorbers arrive with a visible pink indicator — easy to verify freshness
- Thick Mylar with a 5-layer barrier, BPA and PFAS free
- Seals quickly with a hair iron or clothes iron
Minor concerns
- Fulfillment issue: a small number of packs arrive missing one bag
- Bag thickness (5 mil) is lower than the 15 mil DEIAO or SHXWELL options
Get this if: you want ShieldPro’s reliable bag quality paired with oxygen absorbers that have more consistent positive reviews.
Consider the 15 mil DEIAO set (product 2) if: you need thicker bags for sharp or heavy loads and do not mind the taller shape.
Understanding the Specs
What “Mil” Means (Bag Thickness)
A “mil” is one-thousandth of an inch — the standard way Mylar bag thickness is measured. A bag labeled 5 mil means each side is 5 mil thick. Thicker bags (like 15 mil total) resist punctures from sharp food edges like spaghetti or freeze-dried chicken. Thinner bags (5-7 mil) work fine for soft grains and pasta but need careful handling with sharp items. For long-term storage, 10 mil total or higher is a safe starting point.
Oxygen Absorbers and CC Ratings
An oxygen absorber packet removes the oxygen inside a sealed container. The “cc” number (cubic centimeters) tells you how much oxygen it can absorb. A 300cc absorber fits a quart bag, a 400cc fits a gallon bag, and a 2000cc works for a 5-gallon bag. Bags do not shrink like a vacuum bag; absorbers remove only the oxygen (about 21% of the air), so 4/5 of the air volume stays. Use the correct cc rating — too small and oxygen lingers, spoiling your food.
