What are Mylar Bags?

Mylar bags are a type of flexible, durable packaging made from polyester film coated with aluminum. This unique composition provides exceptional barrier properties against moisture, light, and oxygen, making them ideal for protecting contents from external factors that can degrade quality.

Advantages of Using Mylar Bags

Using mylar bags offers a range of benefits:

  • Superior Protection: Mylar bags’ high-barrier construction shields items from moisture, oxygen, UV light, and pests.
  • Extended Shelf Life: With minimal exposure to air and humidity, perishables remain fresh for longer.
  • Versatile Applications: Mylar bags cater to various industries, including food, pharmaceuticals, electronics, and emergency preparedness.

Types of Mylar Bags

Flat Mylar Bags

Flat mylar bags are a simple and cost-effective option for packaging products that don’t require a stand-up feature.

Mylar Stand-Up Pouches

Mylar stand-up pouches are convenient and visually appealing, making them popular for retail packaging.

Mylar Ziplock Bags

Mylar ziplock bags combine the benefits of mylar material with a resealable ziplock closure, perfect for items accessed multiple times.

Selecting the Right Size

Choosing the appropriate size is crucial. Ensure the bag provides enough space without excessive air, which could lead to quicker degradation.

Factors to Consider When Buying Mylar Bags

Material Thickness

Thicker mylar bags offer enhanced durability and protection, but the choice depends on the type of items you intend to store.

Oxygen and Moisture Resistance

Opt for bags with superior oxygen and moisture barrier properties to prevent spoilage and maintain product integrity.

Closure Mechanism

Select a closure that suits your needs – options include heat sealing, ziplocks, and resealable tape.

Transparency and Visibility

For retail purposes, transparent windows on mylar bags allow customers to view the product without compromising its protection.

Applications of Mylar Bags

Mylar bags find application in various fields:

  • Food Storage: Grains, dried fruits, and dehydrated meals remain fresh and nutritious.
  • Electronics Protection: Sensitive electronic components are safeguarded from moisture and static.
  • Documents and Artifacts: Historical documents and precious artwork are shielded from deterioration.

Proper Usage and Storage Tips

For optimal results:

  • Remove excess air before sealing the bag.
  • Store bags in a cool, dark, and dry place.
  • Use oxygen absorbers to further extend shelf life.

Some mylar bags are recyclable, but their environmental impact varies. Consider reusable alternatives if sustainability is a priority.

Frequently Asked Questions (FAQs)

Are mylar bags suitable for long-term food storage?

Mylar bags are commonly used for long-term food storage due to their durability, impermeability to air, moisture, and light, which helps in preserving the quality and shelf life of the stored food. They are often used in conjunction with oxygen absorbers to create an oxygen-free environment, further preventing spoilage.

Can I reuse mylar bags?

Mylar bags can be reused, but their effectiveness for long-term food storage might decrease with each use. Over time, the integrity of the bag, the sealing quality, and the barrier properties might deteriorate, potentially compromising the stored food’s freshness and safety.

How do I seal mylar bags without a heat sealer?

If you don’t have a heat sealer, you can still seal mylar bags effectively using alternative methods:

  • Iron and Parchment Paper: Place the open end of the bag between two sheets of parchment paper and use a household iron on its lowest setting to seal the bag shut. Move the iron along the edge to ensure a consistent seal.
  • Clothes Iron with Silicone Tape: Similar to the above method, but you can use a clothes iron and silicone tape along the edges of the bag to ensure a tight seal.
  • Double Bagging: Place your items in one mylar bag, then insert that bag into another mylar bag. Fold over the open ends and secure with strong tape.

Do mylar bags protect against rodents and insects?

Mylar bags provide a good barrier against rodents and insects, as they are not easily chewed through and are resistant to punctures. However, for extra protection, it’s recommended to store mylar bags in a rodent-proof container and in an environment where pests cannot easily access them.

What is the difference between mylar bags and vacuum-sealed bags?

  • Mylar Bags: These are made from a specific type of polyester film known as Mylar. They are typically used for long-term food storage and are often paired with oxygen absorbers to create a low-oxygen environment that helps preserve food quality. Mylar bags are sealed to prevent air and moisture from entering.
  • Vacuum-Sealed Bags: These are plastic bags that are sealed after removing air from within the bag using a vacuum sealer. While they help reduce the presence of air, they might not provide the same level of protection against light and moisture as mylar bags. Vacuum-sealed bags are often used for short to medium-term storage of items like meats or vegetables.

Both types of bags have their uses, and the choice depends on the specific requirements of the items you’re storing and the duration of storage needed.


Mylar bags offer a reliable and efficient means of preserving the quality of your stored items. Whether you’re a prepper, a retailer, or someone who values freshness, these bags prove to be an essential investment. With a wide range of options available and careful consideration of your specific needs, you can confidently choose mylar bags as your preferred storage solution.
