Mylar Bags vs. Other Food Storage Methods

While mylar bags are highly effective for long-term food storage, it’s worth considering alternative methods. Let’s compare mylar bags food storage with other common food storage options:

Plastic Containers

Plastic containers are convenient for short-term storage but are not as effective as mylar bags for long-term preservation. They are prone to air and moisture penetration, which can lead to food spoilage.

Vacuum Sealing

Vacuum sealing removes air from the packaging, extending the shelf life of certain foods. However, it may not be suitable for all food items, and the cost of vacuum sealing equipment can be prohibitive.


Canning involves preserving food in jars by heat processing and creating a vacuum seal. While canning is a popular method for preserving food, it requires specialized equipment and can be time-consuming. Mylar bags offer a simpler and more cost-effective alternative for long-term food storage.

Common Misconceptions about Mylar Bags

There are some common misconceptions surrounding mylar bags for food storage. Let’s debunk a few of them:

Oxygen Absorbers Are Optional

While mylar bags provide excellent protection against moisture and light, they are not completely airtight. Oxygen absorbers are necessary to create an oxygen-free environment inside the bag, preventing oxidation and spoilage.

Frequently Asked Questions (FAQS)

What Size Mylar Bag Should I Use for food storage?

Mylar bags are available in a variety of sizes, ranging from 1 pint to 6 gallons. A 1-gallon Mylar bag can hold approximately 6-7 lbs of rice. A 5-gallon Mylar bag can hold approximately 33 lbs of rice. Beans, flour, and grains may all be stored in 1-gallon Mylar bags. Even smaller bags are preferable for spices, freeze-dried fruits, and vegetables.

How Much Food Will Fit In Mylar Bag?    

Many factors come into play. The size of the food you’re attempting to store (for example, some beans are smaller than others). Thinner Mylar bags are more flexible as they can hold more food.

What is the Quantity Of Oxygen Absorber in mylar bags food storage?

The amount of oxygen absorbers used is determined by the food’s moisture content. The requirement of an oxygen absorber can be determined using the moisture and oxygen absorber chart. Always be cautious and use more oxygen absorbers than you think you need! Adding more oxygen absorbers has no effect on the food. OAs are inexpensive; it is preferable to spend an extra 25 cents on an additional oxygen absorber than to waste 5 gallons of food when it is most needed.

How To Seal Mylar Bags food storage? 

Mylar bags can be easily sealed with an impact heat sealer or clamshell. Alternatively, a household iron or a hair straightener can be used.

Do You Need To Freeze Foods Before Storing Them In Mylar?

It is not always necessary to freeze food before placing it in a mylar bag. You can do so as a precaution.

Where To Add Oxygen Absorber in mylar bags food storage?

Ideally, the oxygen absorbers should be placed on top of the food before sealing. It can, however, be placed anywhere in the bag.

What Is a Foil Pouch or Mylar Bag?

Foil pouches are essentially stand-up pouches. They are made by laminating several layers of different materials together, just like stand-up bags. The materials used in foil pouches distinguish them from other stand-up pouches. 

What are the best tools for sealing mylar bags for food storage?

The best tools for sealing mylar bags are an impact heat sealer or a clamshell.  A household iron or a hair straightener can be used alternatively.  Tack the mylar bag in the centre position with the plain iron. After that, tack it a few more times. Then, using the flat iron, seal the top completely. Gently squeeze the bag to see if any air is escaping. If so, use the flat iron again until it is completely sealed. Most household clamp-style vacuum sealers are unable to seal standard mylar bags; however, most commercial vacuum sealers can. It is important to note, however, that most mylar bags are not embossed/textured, so a vacuum sealer will not pull the air out.

Are mylar bags for food storage are reusable?

The advantage of buying high-quality Mylar bags is that they are reusable. Simply cut the top near the seal and remove the contents. The bag should be washed, and then dried completely. The bag is then suitable for further use. Every time you reuse the bag, it shrinks slightly because you must cut off the sealed portion. However, if you can reuse the bag three or four times, they become relatively inexpensive. Aside from being reusable, Mylar bags could be cut into smaller sizes to make more bags. To get the most out of your mylar pouches, make sure they’re properly washed after the first use, and then always seal them near the top so you don’t have to cut more away when it’s time to use them again.

How to determine mylar bags for food storage quality?

The thickness of the bag can be used to determine its reliability of the bag. The bag’s durability is proportional to its thickness. The main factor to consider is whether the bag is prepared with aluminium foil but rather an aluminium sheet. Both of these materials have distinct differences. Aluminium foil has a more gleaming surface and is more flexible than sheets. The aluminium foil is thicker and heavier in weight. In comparison, aluminium plating feels lighter and softer than aluminium foil.
