Mylar food storage bags are made from a type of polyester film called BoPET (biaxially-oriented polyethylene terephthalate). They are used to store food for long periods of time, as they provide a barrier against moisture, air, and light, which helps to keep the food fresh and prevent spoilage.
To use Mylar food storage bags, follow these steps:
- Choose the appropriate size of Mylar bag based on the amount of food you want to store.
- Place the food inside the Mylar bag, making sure to leave some space at the top for sealing.
- Add an oxygen absorber to the bag to remove any excess oxygen and further extend the shelf life of the food.
- Seal the bag using a heat sealer or a vacuum sealer. A heat sealer works by melting the top of the Mylar bag to create an airtight seal. A vacuum sealer removes the air from the bag before sealing it.
- Label the bag with the contents and date of storage.
- Store the bag in a cool, dry place away from direct sunlight and heat sources.
It is important to note that Mylar bags are not a complete solution for food storage. They are best used in combination with other food storage methods, such as oxygen absorbers and proper temperature and humidity control.

The shelf life of Mylar food storage bags depends on several factors, including the quality of the bags, how they are stored, and the contents of the bags. In general, Mylar bags can remain usable for several years if they are stored properly.
Mylar bags should be stored in a cool, dry place away from direct sunlight and heat sources. Exposure to heat and light can cause the bags to break down and lose their effectiveness over time. Additionally, the bags should be kept away from sharp objects and chemicals that can damage the bags.
The contents of the Mylar bags can also affect their shelf life. Dry goods such as grains, beans, and pasta can be stored in Mylar bags for several years if they are properly sealed and stored. However, foods with high moisture content or high oil content may not last as long and may require additional measures to prevent spoilage.
It is important to check the integrity of Mylar bags periodically to ensure they are still airtight and have not been damaged. If a bag appears to be damaged or has been punctured, it should be replaced.
