In this article, I will guide you through the process of using Mylar bags for food storage. Mylar bags provide an airtight barrier against oxygen, light, moisture, and contaminants, making them an excellent choice for long term food storage. Whether you are prepping for emergencies or simply looking to extend the shelf life of your food, Mylar bags are a reliable and efficient solution.

Why Choose Mylar Bags?

Mylar bags offer several advantages when it comes to food storage. They are known for their ability to create a protective barrier that keeps out oxygen, light, moisture, and contaminants. This barrier helps to prevent spoilage, mold, and infestations, keeping your food fresher for longer periods. Additionally, Mylar bags can withstand extreme temperatures, making them suitable for both cold and hot storage environments.

Storing Different Types of Food

You can store a wide variety of food items in Mylar bags. Dry goods such as pasta, rice, beans, and sugar are perfect candidates for Mylar bag storage. Grains, cereals, and even pre-packaged meals can also be safely stored in these bags. The key is to ensure that the food items are properly sealed inside the bags before storing them in a cool, dry place.

Protecting and Extending Shelf Life

One of the main benefits of using Mylar bags for food storage is their ability to protect and extend the shelf life of your food. As mentioned earlier, the airtight barrier provided by Mylar bags keeps out oxygen, which is a major cause of food spoilage. By minimizing the exposure to oxygen, Mylar bags help to preserve the quality and freshness of your food items.

Different Sizes for Different Needs

Mylar bags come in various sizes to accommodate different storage needs. Whether you have a small quantity of food or need to store a large bulk, there is a Mylar bag size that suits your requirements. From small snack-sized bags to large gallon-sized bags, you can choose the appropriate size based on the amount of food you intend to store.

Using Oxygen Absorbers

When using Mylar bags for long term food storage, it is highly recommended to use oxygen absorbers. Oxygen absorbers are small packets that contain iron powder and other ingredients designed to remove excess air from the bags. By removing oxygen, oxygen absorbers help to prevent the growth of bacteria, mold, and other harmful organisms.

Determining the Amount of Oxygen Absorbers

The amount of oxygen absorbers needed depends on the type and volume of food being stored. As a general guideline, it is better to use slightly more oxygen absorbers than recommended to ensure their effectiveness. For example, if a recipe calls for 50 oxygen absorbers, using 60 or 70 might be a better choice. It is always better to be safe than sorry when it comes to preserving your food.


In conclusion, Mylar bags are an excellent choice for long term food storage. They provide a reliable and airtight barrier against oxygen, light, moisture, and contaminants. With the ability to store various types of food items and extend their shelf life, Mylar bags offer convenience and peace of mind. By using oxygen absorbers and properly sealing the bags, you can ensure the effectiveness of your food storage system. So, why not give Mylar bags a try and take a proactive step towards securing your food supply for the long haul?
