Mylar Bags for Long-Term
Food Storage: A Guide

Ever noticed that “space food” and camping/hiking “survivalist” type foods are often packaged in shiny mylar packaging instead of plastic bags? Well, it isn’t because it looks futuristic -- it’s because mylar packaging is accessible and is simply the best packaging and long-term storage method for sundries and dry foods like rice, beans, and flour. In fact, some foods packaged in mylar can last for up to 30 years, and others can even be kept indefinitely!

Using Mylar to Store Food

Mylar packaging is made from several layers of laminated food-grade plastic and aluminum. The fact that there are multiple layers means that the food inside is protected from exposure to oxygen and the elements. They’re ideal for long-term food storage for a few reasons. First, they are very strong and can resist punctures, rips, and tears, at least to a degree. Second, the material is flexible, meaning you can store foods of many shapes and sizes in mylar. And finally, it has built-in barrier properties. As mentioned above, this means the food inside is protected from light and air. 

If purchased from a company like CarePac, mylar bags are also an economical choice to store food, as you can purchase them in bulk and save money. But, you also aren’t tied to large quantities with CarePac, as we’re proud to offer low MOQs for small companies or product runs. 

Advantages and disadvantages of storing food in a mylar bag

As you can see, a sealing mylar bag is best for dry food storage, such as nuts, crackers, dehydrated fruits and vegetables, and sundries, like flour and rice. We’ll discuss which foods can be stored in a mylar bag (and for generally how long) in the next section.

Which foods can be stored in mylar bags?

Dry, low-fat foods can be stored in mylar food bags long-term. Any food with moisture content may start to go bad in mylar bag storage, and there is a risk of botulism if food is packaged and stored incorrectly. All food should be stored with an oxygen absorber, and only foods with 10% or less moisture content can be packaged in mylar bags with an oxygen absorber.

Here is just a small sampling of the types of food that can be stored in mylar food bags long-term with an oxygen absorber and how long you can expect them to last:

Which Foods CANNOT Be Stored In Mylar Bags?

Due to their moisture content and the risk of botulism, any foods with more than 10% moisture content cannot be stored in sealing mylar bags and should be stored in another type of bag, like plastic bags. Fruits and vegetables must be dehydrated before storing, and meats, nuts, and legumes will go rancid regardless of how they’re prepped or stored.
