Getting started with food storage means learning proven methods that help preserve them. Two common starting points for beginners are Mylar bags and vacuum sealing. This guide explains how both long-term food storage options function and teaches you when to use each based on your personal storage goals.
Long-Term Food Storage Methods
Long-term food storage helps extend your food’s shelf life and helps you maintain a steady supply of essential items. This is especially crucial when grocery access becomes limited, or prices rise unexpectedly. Additionally, stored food spoils when exposed to oxygen and moisture. To preserve for the long-term, use storage techniques that keep containers sealed tightly and reduce oxygen exposure. Here are the two most common storage options:
What are Mylar Bags?
Mylar bags are made from a strong, light-blocking plastic film. People use them to store dry foods like rice, flour, pasta, beans, and oats. These bags are suitable for storing food for at least a year.
The sealing process is simple. To pack a Mylar bag, put in the dry goods and throw in an oxygen absorber to slow spoilage inside. Then seal the top seam using heat from a clothes iron or hair straightener. Afterward, place the sealed bags in bins or buckets with lids then store them in a cool, dry place. Keep the bags sealed until you’re ready to use the items.
What is Vacuum Sealing?
Vacuum sealing works differently from Mylar storage as it’s geared for foods you plan to access more often. It’s a good choice for items such as raw meat or dry goods that you store in the fridge or pantry and plan to use soon. Use a machine or pump to remove air and tightly seal the bag or jar to limit oxygen exposure.
Once sealed, proper labeling and portioning help keep containers organized. Divide food into portions then label bags or jars after sealing to make it easier to find the specific item you need. Overall, vacuum sealing makes it easier to rotate food you use regularly. Although this method reduces oxygen exposure, it doesn’t create the same long-term conditions as Mylar with oxygen absorbers.
Which Method Fits Your Food Storage Plan?
Choosing between these two food storage methods depends on how often you access the food. If your supplies need to sit untouched for months or years, use Mylar bags. As mentioned above, they can store bulk items for a long time.
If you tend to grab from your stored food regularly, you’ll need vacuum sealing to make it easier to open and close the bags. Still can’t decide? Why not use both methods to store your long-term staples and rotation-ready items?
Long-Term Food Storage: Lock It In for the Long Haul
To get the best results, match your long-term food storage method to how and when you plan to use your supplies. After choosing, start packing what you have, then test one method to see how it preserves food over your planned timeframe. For vacuum sealing, check within weeks. For Mylar, inspect your storage area every few months to ensure that the contents of the sealed bags remain undamaged.

✅ 10 FAQs: Long-Term Food Storage
- How long can food last in Mylar bags?
Dry goods stored with oxygen absorbers can last up to 10–25 years, depending on the item and conditions. - Do I need a special machine to seal Mylar bags?
No. You can use a household clothes iron or a hair straightener to seal the bag. - What foods should not go in Mylar bags?
Avoid storing high-moisture or oily foods in Mylar bags. These can spoil or go rancid even with oxygen removed. - How often should I check vacuum-sealed food?
Check sealed food every few weeks for signs of broken seals, discoloration, or moisture build-up. - Can I reuse Mylar bags?
Only if you cut them carefully and reseal above the previous line. Avoid reusing bags with food residue. - Do vacuum-sealed foods need refrigeration?
Yes, for perishable items. Vacuum sealing extends shelf life but doesn’t replace cold storage. - What size Mylar bag should I use?
Use sizes that match your portioning needs. One-gallon bags are common for pantry staples. - Are oxygen absorbers the same as silica packets?
No. Oxygen absorbers remove oxygen; silica packets control moisture. Both serve different roles in food storage. - Can I vacuum seal jars for dry storage?
Yes. With the right jar sealer attachment, you can vacuum seal dried goods in mason jars. - Is it safe to store rice or beans without any special packaging?
Not long term. Without oxygen removal or sealed containers, these foods are vulnerable to pests and spoilage.
