What is a Mylar Bag?

Before we get into the full details about how long does dehydrated food last in mylar bags, it is important to understand what mylar bags really are. Mylar bags are basically versatile and durable food storage pouches famous for enhancing the product’s shelf life. The second question you might most likely have is “What are mylar bags made of?”. Well, that’s the second most valid question that needs to be answered to fully understand them.

Custom Mylar bags are made from a polyester film, which is also called BoPET, layered with aluminum foil, which enhances its barrier properties. As we have already said, these bags are designed to protect your content by keeping it safe from external factors like light, oxygen, and moisture. They work great in terms of food storage and help prevent the risk of spoilage. Below are the key features of Mylar bags:

Durable and Puncture Resistant

Mylar bags are famous for being strong and durable packaging options. They offer excellent durability and are also puncture resistant. They are strong because of their multi layered construction and the material used to make them. As we have already discussed, mylar bags are made from polyester film BoPET, which is laminated with polyethylene and aluminum foil.

Thus, they prevent punctures, tears, and environmental factors that could degrade the value of the food products you store.

Flexible Food Packaging Option

Mylar bags are known for being flexible food packaging options. The material used to make custom clear Mylar bags is inherently flexible, which allows them to bend easily. You can fold them without a hassle, without worrying about punctures because it will never happen. They are lightweight and are designed to easily adjust to the shape of the products. That way you can store them easily.

Resealable Packaging Pouches

One of the main reasons why custom stand up pouches are loved so much by so many people is their ability to be resealed. These bags come with a zipper closure that allows you to reseal them. That way, you can utilize them multiple times, making them a suitable food packaging alternative. For an air tight closure, you can heat seal them to increase the shelf life of your food products.

How Mylar Bags Help Preserve Dehydrated Food for a Long Time?

Storing dehydrated food for a long time is a real deal, and mylar bags are often viewed as the most suitable choice for long term food storage. We have three main enemies: moisture, light, and oxygen.

According to market research, the global dehydrated food market is flourishing. It was worth $78.8 billion in 2024 and is expected to reach $107.5 billion in 2032. Mylar bags are playing a major role in that growth rate. They are the ones that cause spoilage and degrade your product’s value. At ColorWing, we offer you the best mylar bags that help you with long term food storage.

If your food products get exposed to any one of them, they could lose their crisp. Below is how mylar bags help preserve dehydrated food for a long time:

Moisture:

Moisture is one of the biggest problems for dehydrated food. If your dehydrated food gets exposed to even a tiny amount of water, it could lead to mold. Which further leads to the birth of bacteria, which cause food spoilage. Since mylar bags are made of thick layers, they keep moisture out. Mylar bags have the barrier properties to keep the light and moisture out.

All you need to do is seal them properly. Then these mylar bags will act as a shield, helping you lock in the dryness. This ultimately leads to longer shelf life of dehydrated food products.

Oxygen:

Oxygen also leads to the spoilage of your dehydrated food that is why oxygen absorbers are a must . They cause food to break down with time and lead to bad smells. Your dehydrated food could lose all its nutrients. That’s why many people use oxygen absorbers when choosing Mylar bags for storing dehydrated food. One gallon of mylar bags needs a 300–500 cc oxygen absorber in order to stay fresh.

Light:

Exposing dehydrated food to light can also cause food breakage. They can cause your dehydrated food to lose its nutrients faster. It will not only affect the product's flavor but also lose its integrity. This is where mylar bags come as a hero again. They are designed to block light in order to keep your food fresh. They help keep your food products safe from discoloration and help maintain the flavor.

To make sure your mylar bags protect your food product, you also need to put some effort. You will need to first heat seal them and then store them in a cool, dark place to increase the shelf life.
