A people continuously ask is: how long do beans last in Mylar bags, and how do you store them the right way?

If you want to store food long-term, consider buying beans because they are an economical source of nutrients and can last for years when stored properly. 

Lets break it down.

Short Overview

Beans can last 15 to 30 years in Mylar bags when sealed with oxygen absorbers and stored in a cool, dark place, with dried beans typically reaching the longer end of that range. Pinto beans generally last 15 to 25+ years under the same conditions. To store them properly, fill the bag with dry beans, add an oxygen absorber, remove excess air, and heat seal it tightly. A standard 1-gallon Mylar bag holds about 6 to 7 pounds of dried beans, depending on their size.

How Long Do Dried Beans Last in Mylar Bags?

Properly stored beans can last decades (up to 30 years) in Mylar bags by eliminating oxygen, moisture, and light.

Factors Determining Shelf Life:
- Exposure to oxygen
- Temperature
- Light
- Moisture

Beans will go into a near “paused” state when sealed properly in an airtight mylar bag with oxygen absorbers and kept at cool, dark temperature. Without oxygen means that they will not harbor any bugs, mold, or virtually any deterioration.

How Long Do Pinto Beans Last in Mylar Bags?

Pinto beans can last 15 to 25+ years in Mylar bags when sealed with oxygen absorbers and kept in stable conditions.

• If stored properly, pinto beans will last for 15-25 years in mylar bags
• If stored in ideal storage conditions: they can last even longer than 25-years (stable temps under: 70 degrees).
• Due to the ability of pinto beans to hold their shape after cooking and due to the textures after cooking, they are a great candidate for long-term storage.

How to Store Beans in Mylar bags (step by step)

Fill the bag with dry beans, add an oxygen absorber, remove excess air, heat seal the bag, and store it in a cool, dark place.

You Will Need:

1. Mylar Bags (5 mil or thicker recommended)
2. Oxygen Absorbers (for one-gallon quantity use 300-500cc)
3. Heat Sealer or Flat Iron
4. Food Grade Bucket (optional, but recommended)

Instructions: 

• Fill the Mylar bag with dry beans
• Add the right amount of oxygen absorber
• Press out as much excess air as you can
• Fully heat seal the bag
• Store it in a cool, dark place such as a basement or pantry

That is all you need to do; you do not need to use a vacuum sealer; the oxygen absorber does all of the work.

How Many Beans Fit into a 1-Gallon Mylar Bag?

A one-gallon Mylar bag holds approximately:

6 to 7 lbs of dried beans

Beans come in different sizes, and depending on the type, they will fill more or less space

For example: smaller beans, such as black beans, will take up a smaller space than larger beans, such as kidney beans.

To get the best results, always leave a little bit of space at the top when you are filling the bag so that you can properly seal it.

All in all, a 1-gallon Mylar bag holds about 6 to 7 pounds of dried beans, depending on the bean size.

What Makes Mylar Bags So Good for Storing Beans

Mylar bags are not just thick plastic bags. They are a multi-layered barrier to protect food from moisture, oxygen, and light.

By using both mylar bags and oxygen absorbers, you are virtually freezing the food for as long as possible without having to actually freeze it.

Why Are More Brands Changing to Printed Mylar Packaging for Dry Food

Food brands are beginning to use printed mylar style packaging for products like beans, rice, and grains.

Here’s why:

1. Longer shelf life = less spoilage.
2. Better protection than standard plastic bags.
3. Better brand identification with high-quality printing.
4. Resealable.
5. More durable for the consumer.

This is why companies are moving to custom printed mylar bags and producing packages that actually protect the product and not just packages that look good on a shelf.

Summary

Beans stored in Mylar bags can last up to 30 years when sealed with oxygen absorbers and kept in a cool, dark place, with most dried beans falling in the 20 to 30 year range and pinto beans typically lasting 15 to 25+ years. Proper storage involves filling the bag with dry beans, adding an oxygen absorber, removing excess air, and heat sealing it completely. A 1-gallon Mylar bag usually holds around 6 to 7 pounds of beans, depending on the type and size.

If you are wondering how long beans will last in mylar bags, you need to do it properly to store food for decades.

Once you have stored the food properly, you will have the longevity of one of the most inexpensive and dependable food sources around.

There aren’t that many ways to store food and get that kind of return.
