What to Know about Mylar Bags for Food Storage?
To keep food fresh, packaging is equally as important as the product itself. When products are stored for a long period, bad packaging can let in moisture, cause oxidation, and lose nutrients. That's why people all over the world use mylar bags to keep food fresh in their homes and huge food companies.
MTPAK makes and sells high-barrier Mylar bags that are made just for food industries that need dependable storage options. Mylar is still one of the best ways to safeguard product quality and extend shelf life, whether it's for disaster preparedness, retail packaging, or export distribution.
What Are Mylar Bags Made of?
Mylar bags are made out of BoPET (biaxially-oriented polyethylene terephthalate) film. It is a robust, flexible polyester that keeps light, air, and moisture out. Mylar bags are commonly laminated with layers of aluminum foil and polyethylene to build a barrier with multiple layers that helps them work better.
This design keeps oxygen, moisture, and UV radiation out of the bags, which are the main things that make food go bad. This makes the bags superior than normal plastic pouches. In the end, the packaging lasts a long time and keeps everything safe and fresh.
Benefits of Using Mylar Bags for Food Storage
The way the material is created makes Mylar bags perfect for storing food. There are a number of benefits:
Longer shelf life
The high-barrier layers slow down the breaking down of things. When mixed with oxygen absorbers, they keep dry foods like grains, beans, and pasta fresh for years or even decades.
Durability and protection
Mylar bags are better than thinner plastics at keeping food safe from moisture, bugs, and harm that can happen when you handle it or store it.
Flexibility and personalization
Because they come in many shapes, sizes, and ways to close, Mylar bags are great for a lot of different kinds of food. You could even add pictures to them to help your brand stand out and make them easier to find in stores.
Storage at a low cost
Mylar bags are a good alternative for those who are making emergency supplies at home or corporations that are packing a lot of things. They are easy to find and not very pricey.
How Long Does Dehydrated Food Last in Mylar Bags?
One of the main reasons to use Mylar bags to store food is that they keep food fresh by keeping out air, moisture, and light. Dehydrated meals can last anywhere from a few months to several decades, depending on the type of food.

How to Use Mylar Bags for Food Storage?
If you're a brand or a customer who wants to know how to utilize Mylar bags to store food, here are some crucial measures to follow:
1. Pick the correct size and thickness of the bag. Thicker Mylar (5–7 mil) is needed for heavier meals or long-term preservation.
2. Fill with dry items that don't have a lot of moisture. Grains, beans, dehydrated fruits, pasta, or powdered goods work well.
3. Add oxygen absorbers. These packets lower the amount of oxygen in the bag to less than 0.1%, which helps keep food from going bad.
4. Make sure the bag is sealed correctly. Heat sealing is the best way to keep things safe for a long time.
5. Keep it in a cool, dark spot where it won't get too much sunshine or humidity.
