People who buy in bulk or stock their pantry eventually run into one common problem: the food doesn’t stay fresh as long as they expected.
The food lasts only as long as the container protecting it.
A tiny puncture in a bag or a loose lid on a jar is all it takes for air, moisture, and pests to slip in and ruin weeks’ worth of food. That’s where choosing the best food storage method becomes the difference between saving money and wasting it.
This guide breaks down how Mylar bags, airtight containers, and glass jars each work, what they protect best, and how to match them with the right foods for the most reliable food storage.
Mylar Bags for Long-Term Storage Solution
Mylar sits in a category of its own because it creates the kind of barrier that regular packaging cannot.
The foil-lined material blocks light completely, seals tightly against airflow, and holds its structure for years without thinning or cracking.
When paired with oxygen absorbers, it creates a low-oxygen environment that keeps dry foods stable for up to 30 years. That’s why it’s the go-to choice for long-term bulk storage rather than short pantry use.
Mylar works best with low-moisture, low-oil foods, with less than 10% moisture. These staples sit safely inside a sealed bag because they don’t spoil quickly and don’t carry enough moisture to grow bacteria.
Ideal Food Options to Store in Mylar Bags
These foods stay dry, firm, and usable even after decades when sealed correctly. They hold their texture, keep their flavor, and remain dependable whether you’re stocking a pantry or building a long-term reserve.
- White rice
- Dry beans
- Rolled oats
- All-purpose flour
- Pasta
- Powdered milk
- Freeze-dried meals and ingredients
- Cat food (under 10% moisture or fully freeze-dried)
- Dog food (under 10% moisture or fully freeze-dried)
Foods Not to Store in Mylar Bags
Some foods, however, never belong inside Mylar because they carry too much fat or moisture. These break down fast, turn rancid, or grow bacteria, no matter how good the seal is.
- Nuts and nut mixes
- Jerky unless bone-dry
- Sticky dried fruit
- Trail mixes
- Kibble or pet food above 10% moisture
- Anything oily, bendable, or soft
Why Mylar Bags Are One of the Best Food Storage Methods
- Blocks oxygen and light
- Works seamlessly with oxygen absorbers
- Keeps pests away (pantry moths, weevils, ants)
- Slows oxidation and flavor loss
Wallaby Mylar bags use thick 5 to 7.5 mil layers that stand up to long-term storage, making them a solid choice for anyone building a reliable food reserve. With the right food and a proper seal, Mylar bags become the foundation of a decades-long storage plan.
Glass Jars for Small-Batch, Short-Term Storage
Mason jars are the best food storage solution for small food portions. Their solid glass walls make it easy to see what you’ve stored, and the airtight LockLid system creates a clean, reliable seal that protects food from everyday exposure to air and moisture.
For spices, baking ingredients, and dehydrated snacks you reach for often, jars offer convenience.
Best Foods to Store in Mason Jars (Short-Term)
These foods stay crisp and aromatic because the airtight seal blocks humidity, which is the main reason flavors fade prematurely.
Wallaby Mason Jars use premium food-grade annealed glass, making them safe for everyday kitchen handling, microwaving, dishwashing, and even freezing.
The included dissolving labels help keep your pantry organized without sticky residue. Here’s a list of foods you can store in mason jars.
- Spices and seasoning blends
- Dried herbs
- Sugar and salt
- Baking ingredients (baking soda, cocoa, chocolate chips)
- Dehydrated fruit or veggie chips (short-term)
- Small-batch rice, pasta, and lentils
- Loose-leaf tea and coffee grounds
Foods That Are Not Ideal for Glass Jars (Long-Term)
Glass jars offer visibility and convenience, but they don’t block light or create the long-term, oxygen-free environment necessary for storing food for up to 30 years.
They’re only perfect for daily scooping, small-batch prepping, and short-term pantry organization. For weekly or monthly use, jars keep your essentials tidy, accessible, and reliably sealed.
You should not store the following types of food in mason jars.
- Anything requiring light protection
- Freeze-dried meals stored for decades
- Bulk grains needing oxygen removal
- Foods affected by heat swings in garages or sheds
Airtight Containers for Everyday Pantry Use
Airtight containers keep frequently used foods fresh, stop pests from creeping in, and make scooping or pouring fast.
These containers don’t create decades-long shelf life like Mylar bags, but they excel at short-term storage where convenience matters as much as protection.
Best Foods to Store in Airtight Containers
These foods benefit from a tight seal that shields them from humidity. Even small moisture changes can turn cereal soft, stale coffee loses aroma within days, and pantry pests sniff out bags faster than you’d expect.
Once placed inside a solid airtight container, these items keep their texture, flavor, and smell far better than they do in the original packaging. Here’s what to store in airtight containers.
- Cereal
- Coffee grounds and whole beans
- Snacks (crackers, chips, pretzels)
- Pasta and noodles
- Cat or dog kibble for weekly rotation
- Flour for short-term baking use
- Sugar and salt for quick access
Foods You Should Not Store in Airtight Containers for Long-Term Use
These foods need stronger barriers, light protection, or oxygen absorbers, which are conditions that airtight containers don’t provide.
- Freeze-dried meals
- Bulk grains meant for multi-year storage
- Oily foods (nuts, seeds)
- Powdered foods are prone to moisture clumping
Choose containers with gasket lids for an airtight seal. For larger quantities, buckets with gamma lids keep contents accessible without sacrificing tight closure.
