Mylar packaging has revolutionized the way we store and protect various products. Mylar is a type of polyester film known for its superior barrier properties and high tensile strength. This packaging solution has found widespread use in industries ranging from food preservation to electronics due to its durability and versatility.
What is Mylar?
Mylar packaging is a trade name for biaxially oriented polyethylene terephthalate (BoPET) film, which is known for its exceptional strength and durability. Developed by DuPont in the 1950s, Mylar has become synonymous with high-performance packaging materials. The film is created through the stretching of polyethylene terephthalate (PET) in both the machine direction and transverse direction, giving it its characteristic strength and barrier properties.
Key Benefits of Mylar Packaging
Superior Barrier Properties
One of the most significant advantages of Mylar packaging is its excellent barrier properties. Mylar films are highly resistant to oxygen, moisture, and light, making them ideal for preserving the freshness and quality of perishable goods. This barrier protection is crucial for products that are sensitive to environmental factors.
Durability and Strength
Mylar is renowned for its durability. The film is resistant to punctures, tears, and abrasions, ensuring that the contents remain protected during shipping and handling. This makes Mylar packaging a preferred choice for products that require robust packaging solutions.
Flexibility and Versatility
Mylar packaging is incredibly versatile and can be used for a wide range of applications. It can be easily laminated with other materials to enhance its properties, printed for branding purposes, and sealed to create airtight packages. This flexibility allows manufacturers to tailor the packaging to meet specific needs.

Lightweight and Cost-Effective
Despite its strength, Mylar is lightweight, which can significantly reduce shipping costs. Its durability also means less material is needed compared to other types of packaging, making it a cost-effective solution for many businesses.
Applications of Mylar Packaging
Food Industry
Mylar packaging is widely used in the food industry due to its ability to preserve the freshness and extend the shelf life of various products. Common applications include:
- Snack Foods: Mylar bags are commonly used to package snacks such as chips, nuts, and dried fruits. The barrier properties prevent moisture and oxygen from degrading the product.
- Coffee and Tea: Mylar packaging protects the aroma and flavor of coffee and tea by preventing exposure to air and light.
- Emergency Food Supplies: Mylar is a popular choice for packaging emergency food supplies due to its durability and long shelf life.
Electronics and Aerospace
The electronics and aerospace industries also benefit from the unique properties of Mylar. It is used to protect sensitive electronic components from moisture and static electricity. In the aerospace sector, Mylar is used for insulation and as a protective barrier against harsh environmental conditions.
Medical and Pharmaceutical
Mylar packaging is used to ensure the sterility and integrity of medical and pharmaceutical products. Its barrier properties protect against contamination, making it ideal for packaging medications, medical devices, and diagnostic kits.
How to Use Mylar Packaging
Storage and Preparation
To maximize the benefits of Mylar packaging, it is essential to use it correctly. Here are some tips for effective use:
- Clean and Dry: Ensure that the products to be stored are clean and dry. Moisture can compromise the integrity of the package.
- Use Oxygen Absorbers: For food storage, consider using oxygen absorbers to further extend the shelf life of the product. These absorbers help to remove any residual oxygen within the package.
- Heat Sealing: Properly heat-seal the Mylar bags to create an airtight seal. This can be done using a standard heat sealer or an iron set to a suitable temperature.
Storage Conditions
Mylar-packaged products should be stored in a cool, dry place away from direct sunlight. Extreme temperatures and humidity can affect the integrity of the Mylar film and the quality of the contents.
Conclusion
Mylar packaging offers an unparalleled combination of strength, durability, and barrier protection, making it an ideal choice for a wide range of applications. From preserving the freshness of food to protecting sensitive electronic components, Mylar continues to prove its value in various industries. By understanding how to properly use and store products in Mylar bags, businesses and consumers can take full advantage of this innovative packaging solution.
