Mylar, a plastic film commonly used in balloons, is a unique type of stretched polyester film, also known as BoPET. Its non-stretchability and metallic coating make it challenging to recycle through standard methods. While some companies, like TerraCycle, offer specialised recycling programs for Mylar, most local recycling centres lack the capacity or choose not to recycle it due to the difficulties in separating its layers and the risk of it getting caught in machinery.

What You'll Learn
Mylar is a plastic film with a metallic coating
Mylar is a unique type of stretched polyester film, commonly known as BoPET (biaxially oriented PET film). It is a plastic film with a metallic coating, giving it a shiny, reflective appearance. This coating is not real metal, which means that Mylar cannot be recycled as metal. Mylar is most commonly found in balloons, but is also used in food packaging, such as juice and energy bar wrappers, and gift wrap.
The metallic coating on Mylar means that it cannot be recycled as plastic either. Most local recycling centres do not recycle Mylar because it gets caught in the machinery and is difficult to separate from other materials. As a result, Mylar often ends up in landfills or the ocean, causing harm to the environment and animals.
However, some companies, such as TerraCycle, are working to recycle Mylar. They offer Zero Waste Boxes where people can send their Mylar waste to be turned into plastic pellets, which are then used to create other products like benches.
To reduce the environmental impact of Mylar, it is important to dispose of it properly or reuse it. Some ideas for reusing Mylar include using it as gift wrap or finding community recycling programs, like Terracycle's snack bag recycling program.
While Mylar presents challenges in terms of recyclability, proper disposal and reuse can help minimise its impact on the environment.

Mylar balloons are not easily recycled
Mylar is a unique type of stretched polyester film commonly known as BoPET (biaxially oriented PET film). It is often used in balloons, giving them a metallic, shiny appearance. However, this very quality that makes them attractive also makes them a nightmare to recycle.
Mylar balloons are not easily recyclable because they are considered “multi-layered” items. The thin plastic layer is fused with a metallic foil layer, which is challenging to separate. This fusing of layers means that waste management centers have a difficult time separating the two, making the recycling process expensive and time-consuming.
Additionally, the flimsy nature of Mylar balloons means they can easily get caught in the gears of recycling machinery, causing operational disruptions and costly repairs. This is a common issue with flexible films, which are not suitable for curbside recycling programs. The process of separating the layers of metalized film requires specialized and expensive equipment, which many recycling centers do not have access to.
While some companies, like TerraCycle, offer "Zero Waste Box" solutions to recycle Mylar and turn it into plastic pellets, most local recycling centers are unable or unwilling to recycle Mylar due to the challenges and expenses involved. As a result, Mylar balloons often end up in landfills or oceans, causing harm to the environment and animals. Therefore, it is essential to dispose of Mylar balloons properly or find ways to reuse them.

Mylar is not biodegradable
Mylar is a unique type of stretched polyester film commonly known as BoPET (biaxially oriented PET film). It is often coated with aluminum and widely used for packaging food products. Mylar is not biodegradable due to several reasons:
Firstly, Mylar is not biodegradable because it is a type of plastic, and plastic is a non-renewable resource. Once the crude oil used to create plastic products like Mylar is depleted, there will be no more available to make new products. Mylar, therefore, has limited eco-friendly disposal options.
Secondly, Mylar does not decompose naturally or easily. It is resistant to microorganisms, so it cannot be broken down by bacteria and other organisms that typically facilitate decomposition. Even when exposed to certain conditions, Mylar either does not decompose at all or takes a very long time to do so.
Thirdly, Mylar's flexible plastic composition poses challenges for recycling programs. It tends to get caught in the machinery of materials recovery facilities, leading to costly repairs and disruptions in operations. This issue is exacerbated when Mylar is coated with a thin layer of metal, as in the case of Mylar balloons, also known as foil balloons.
Additionally, Mylar's multi-layered composition further complicates its recyclability. Before multi-layered films can be recycled, the different layers must be separated, which is an energy-intensive and expensive process. Most recycling facilities lack the specialized equipment or financial justification to undertake this separation process, resulting in Mylar often ending up in landfills or contributing to the significant amount of plastic pollution in the ocean.
While Mylar itself is not biodegradable, it can weaken over time due to prolonged exposure to elements like waves, wind, or sunlight. However, this does not make it environmentally friendly. The only eco-friendly aspect of Mylar is its reusability. Mylar bags can be washed and reused multiple times, reducing the need for frequent disposal. Nonetheless, the overall impact of Mylar on the environment, particularly marine life, remains detrimental.

Mylar is a brand name for stretched polyester film
The brand name Mylar is owned by DuPont Teijin Films, now known as Mylar Specialty Films. Mylar film has been a prominent and reliable product in the market for over 60 years due to its versatility and durability. It is widely used in electronics, food packaging, industrial applications, and graphics markets. The film's ability to withstand temperatures ranging from -70°C to 150°C, or even -100°F to 300°F according to some sources, makes it a suitable material for various applications.
Mylar film's balanced tensile properties, good adhesion, and ability to resist moisture and chemicals make it ideal for high-volume industrial use. It is also self-venting and extends the shelf life of products, making it a popular choice for food packaging. Mylar film can be cut, laser cut, punched, bent, printed on, or heat-sealed, providing versatility in its applications.
However, recycling Mylar and other flexible films can be challenging. The multi-layered structure of Mylar, often combined with aluminium, makes it difficult to separate and recycle. While some reclaimers have invested in equipment to separate metalized film, the process is generally energy-intensive and expensive. As a result, some recycled metalized wrappers are only partially recycled, with the foil being discarded and only the plastic recycled.

Mylar can be reused or repurposed
Mylar is a type of plastic film that is commonly used in making water bottles and other items. It is stretched very thin and given a metallic coating to achieve a shiny, reflective appearance. This coating is what causes confusion about its recyclability. While Mylar is not typically recyclable, it can be reused or repurposed in several ways.
One issue with Mylar is that it is often found in balloons, which can fly away and end up in the environment, causing harm to animals and the ecosystem. To prevent this, it is recommended to tie Mylar balloons in knots to weigh them down before disposal. However, instead of discarding them, Mylar balloons can be reused as gift wrap. Simply place a smaller box in the centre of the balloon, gather the edges around it, and secure the balloon with a ribbon.
Mylar is also used in food packaging, such as juice and energy bar wrappers, to keep the products fresh and tasty. These wrappers are often multi-layered with plastic and aluminium, making them challenging to recycle. However, companies like TerraCycle are working to make Mylar recyclable. They offer Zero Waste Boxes where people can send their Mylar waste, which is then turned into plastic pellets used to create other products.
Additionally, Mylar can be reused or repurposed in various creative ways. For example, it can be used for arts and crafts projects, such as making collages or decorations. Mylar's reflective surface can add an interesting visual element to artwork. It can also be cut into strips and used as a decorative ribbon or string.
Overall, while Mylar may not be widely recyclable, there are several ways it can be reused or repurposed to extend its life and reduce its environmental impact. By finding new uses for Mylar, we can help keep it out of landfills and minimise its potential harm to the environment.
