What You'll Learn
Mylar is a registered trademark of DuPont Teijin Films
Mylar is a popular choice for food packaging as it is less permeable to gases than other plastics, providing increased shelf life and freshness. It is also used as a laminate with aluminium foil to create a uniform metalised layer, which is often incorrectly referred to as "mylar" by consumers, when the appropriate term is "metallised polyester".
The versatility of Mylar means it is used in numerous applications, from food packaging to electrical and thermal insulation, and even in the creation of party balloons. Its durability and flexibility make it a perfect option for many plastic film applications, and its low vaporisation temperature makes laser cutting an efficient way to process Mylar products into the desired shape.
Mylar is often used as a generic term to refer to any kind of plastic film or sheet, but this does not give enough information about the specific type of plastic required. The true generic terms for this material are polyester film, polyester sheets, or plastic sheet. These sheets are manufactured in a range of styles, finishes, and thicknesses, and can be purchased and applied at scale, making them a cost-efficient choice for many industries.

Mylar is a type of polyester film
Mylar® is a brand name for a thin plastic polyester film, also known as BoPET (biaxially oriented PET film). It is a registered trademark of DuPont Teijin Films, a subsidiary of the DuPont Teijin Corporation. While the term "Mylar" is often used as a generic term for any plastic film or sheet, it specifically refers to this unique type of polyester film with distinct properties.
Polyester film, including Mylar, is known for its exceptional chemical and mechanical characteristics. It is durable, flexible, and capable of retaining its form even when exposed to heat and various other conditions. This makes it ideal for applications where an effective barrier against moisture and gases, particularly oxygen, is required. When used as a laminate with other materials, it enhances shelf life and freshness, making it a popular choice in the food packaging industry.
Mylar's versatility extends beyond food packaging. It is commonly used in helium-filled balloons, electrical and thermal insulation, transparency film, and decorative items. Its ability to maintain its shape and flexibility makes it a preferred material for balloons, as they last longer than latex alternatives. Additionally, Mylar's reflective properties are utilised in items such as kites and emergency "space blankets".
The manufacturing process of Mylar contributes to its popularity. It can be produced in various styles, finishes, and thicknesses, catering to diverse applications. Its low thickness and relatively low vaporization temperature make laser cutting a straightforward and efficient process for shaping Mylar into the desired form. This versatility in manufacturing enables Mylar to be adapted to a wide range of uses.
Mylar's widespread adoption can be attributed to its cost-effectiveness. It is an affordable option for companies seeking an insulating material or a strong seal with heat and moisture resistance. Its scalability and applicability across pricing categories make it a top choice for numerous industries, including packaging and electronics. However, the widespread use of Mylar and similar plastic polyester films has raised concerns about sustainability and environmental impact, as they are not easily recyclable.

Mylar is used in food packaging
Mylar is a polyester film or plastic sheet with a range of applications, including food packaging. It is a registered trademark of DuPont Teijin Films, and was first developed in the 1950s.
Mylar is a popular choice for food packaging due to its durability and flexibility. It is often used for long-term food storage as it provides excellent protection against gases, moisture, odours, and light. Mylar's low vapourisation temperature also makes it easy to cut and shape using laser cutters.
Mylar is commonly used to make packaging bags for a variety of food products, including roasting bags, coffee pouches, and lids for products like yogurt. It is also suitable for packaging dry goods and can extend the shelf life of products. Mylar is particularly useful for packaging sensitive items such as pharmaceutical products, tissue samples, and seeds, as it provides a strong barrier against oxygen and moisture.
The thickness of Mylar bags is important for their effectiveness in food storage. Thicker bags generally provide higher barrier protection. However, certain dried goods, such as potato chips or candy bars, can be packaged in thinner Mylar bags. Mylar bags are also priced based on thickness, with thicker bags being more expensive.

Mylar is used in electrical and thermal insulation
Mylar is a brand name for a specific family of plastic sheet products made from the resin Polyethylene Terephthalate (PET). It is often used as a generic term for any polyester film or plastic sheet. Mylar is widely used due to its excellent chemical, electrical, thermal, and mechanical properties.
Mylar is commonly used for electrical insulation in various applications. It helps channel electricity to where it needs to go, preventing short circuits and eliminating electrocution dangers. Its high dielectric strength, heat resistance, and durability make it ideal for protecting electronic components from electrical interference and environmental factors. Mylar is frequently used to wrap around cables and wires, providing an insulating barrier that prevents electrical currents from escaping and protects against interference. Its flexibility makes it ideal for use in flexible circuits, acting as a substrate or an insulating layer.
Mylar is also used for electrical insulation in transformers and motors, where it plays a critical role in preventing short circuits and electrical arcing. It is used as slot insulation, phase insulation, and wedges for motors and generators, and as core, interlayer, and final insulation for transformers, chokes, and relays. Mylar's low moisture absorption rate helps it maintain its insulating properties in humid or wet conditions, preventing short circuits or electrical degradation.
In addition to its electrical insulation properties, Mylar is also used for thermal insulation. It has a temperature index of 302° F, meaning it will not degrade at service temperatures below this point, providing a long service life for various insulator applications. Mylar can be used at temperatures ranging from -70 °C to 150 °C and does not become brittle with age when used in normal conditions.

Mylar is not easily recyclable
Mylar is a trademarked brand name for a specific family of plastic sheet products made from the resin Polyethylene Terephthalate (PET). It is a type of polyester film or plastic sheet with exceptional mechanical and chemical properties, and it is often used in food packaging, electrical and thermal insulators, and helium-filled balloons. While Mylar is a versatile material, it is not easily recyclable.
Mylar is a plastic that is not biodegradable, and most local recycling centres are unable or unwilling to recycle it. There are two main reasons for this: firstly, Mylar's flimsy nature means it can easily get caught in recycling machinery, causing disruptions to recycling operations. Secondly, Mylar balloons are multi-layered, consisting of a plastic layer fused with a metallic foil layer. This presents a challenge for waste management centres, as separating the two layers is difficult and expensive.
The difficulty in recycling Mylar has led to environmental concerns, as used Mylar often ends up in oceans or landfills. However, some companies, such as TerraCycle, are addressing this issue by offering specialised recycling solutions for Mylar and other difficult-to-recycle materials. TerraCycle, for example, provides Zero Waste Boxes that customers can fill with Mylar and similar waste and then ship back to the company for accurate treatment. TerraCycle transforms this waste into plastic pellets, which can be used to create new products like benches.
While these initiatives are promising, Mylar's recyclability remains limited by the challenges of separating and processing it. Additionally, Mylar's recyclability may vary depending on the specific type and thickness, as well as the capabilities of local recycling centres.
Overall, while Mylar has valuable qualities that make it widely used across various industries, its recyclability is not easily achievable through conventional methods. Specialised recycling programmes and innovative solutions are needed to address the challenges of recycling this unique material.
