What You'll Learn
PET plastic is safe for food and drink
PET plastic, or polyethylene terephthalate, is one of the most common materials used for manufacturing plastic containers and bottles. It is easily identified by the #1 on the container. PET plastic is used to package beverages, food, and household items. It is clear, durable, versatile, and endlessly recyclable.
PET plastic is generally considered safe for food and drink packaging. The US Food and Drug Administration (FDA) and similar regulatory agencies worldwide have approved PET as safe for food and beverage packaging. PET has been used to package beverages, food, and other products for more than 35 years. It does not contain intentionally added Bisphenol A (BPA) or per- and polyfluoroalkyl substances (PFAS), which are known for their potential health risks. By avoiding these harmful substances, PET packaging ensures food remains free from chemical contaminants.
However, it is important to note that there are some concerns about the safety of recycled PET plastic for food and drink packaging. British scientists have reported that PET bottles made of recycled plastic may leak more potentially dangerous chemicals than bottles made of virgin, or new, plastic. Specifically, they found that much more chemicals seemed to leak from drink bottles made of recycled plastic compared to those made of virgin plastic. Among the chemicals that may be present in recycled PET are substances such as antimony, also known as stibium (Sb), and BPA.
Therefore, while PET plastic is generally considered safe for food and drink packaging, it is important to be cautious when using recycled PET and to follow proper recycling and disposal guidelines to minimize any potential risks.

PET is the most widely recycled plastic
Polyethylene terephthalate, or PET, is the most widely recycled plastic. PET is a clear, durable, and versatile plastic that is used to package beverages, food, and household items. It is one of the most common plastics, ranking number one on the list of most commonly used plastics for bottles and containers.
PET is 100% recyclable and can be recycled into its original uses, such as new bottles, as well as many other products like winter jackets, rugs, playground equipment, and dog beds. Using recycled PET (rPET) reduces the environmental impact of plastic production: when used to make new bottles, total energy consumption is reduced by 79% and greenhouse gas emissions are limited by 67%.
PET bottles are also lightweight, flexible, shatter-resistant, and require less energy and water to manufacture and recycle compared to glass, paper, or cardboard. They also have a lower carbon footprint than other materials. For these reasons, PET is a popular choice for packaging designers and manufacturers, as well as consumers.
PET is widely recycled across the world, with Brazil recycling 55% of PET packaging in 2019, and the amount of recycled plastic in bottles more than doubling from 2018 to 2021.

PET is a form of polyester
PET, or polyethylene terephthalate, is a form of polyester. It is a clear, durable, and versatile plastic that is used to package beverages, food, and household items. It is one of the most widely used packaging materials in the world and is valued for its strength, durability, and safety.
PET is commonly used in the production of plastic bottles and containers, and it is easily identified by the #1 on the container. It is lightweight, shatter-resistant, and has excellent clarity, allowing for the transparent appearance of the bottle. PET bottles are also 100% recyclable and can be recycled into their original uses, reducing the need for virgin plastic. The recycling process for PET involves emptying and rinsing the bottles, sorting them by color, shredding them into small pieces, and melting them down to form new products.
PET is also BPA-free, meaning it does not contain Bisphenol A, a chemical linked to potential health concerns. This makes it a safe option for food and beverage packaging, as it does not leach or react with the contents, preserving product purity and ensuring food remains free from chemical contaminants.
PET plastic is used by many global brands, including Coca-Cola, Nestlé, and Danone, for its unmatched scope for design innovation, clarity, shelf appeal, performance, and convenience. It is also environmentally friendly, with a lower carbon footprint compared to other materials such as glass, paper, or cardboard due to its reduced energy consumption during production and transportation.

PET is used for soda bottles
PET, or polyethylene terephthalate, is a clear, durable, and versatile plastic. It is the most commonly used material for making plastic bottles, including soda bottles, due to its unique physical and chemical properties. PET is lightweight, shatterproof, and highly recyclable, making it a sustainable and cost-effective choice for bottling soft drinks and sparkling water.
PET is particularly well-suited for carbonated beverages. Its high strength-to-weight ratio allows it to withstand the internal pressure generated by carbonation, ensuring that the bottles remain intact and do not leak or burst. This feature is due to the chemical structure of PET, which is composed of repeating units of ethylene glycol and terephthalic acid, forming long molecular chains that give PET its remarkable strength and flexibility.
The use of PET bottles for soda offers several advantages. Firstly, they are designed to preserve flavour and carbonation, keeping drinks fresh and fizzy. Secondly, PET bottles are safe, strong, transparent, and resealable, making them convenient and appealing to consumers. The clarity of PET bottles enhances the visual appeal of the product, providing a premium look while maintaining the practical benefits of plastic.
Additionally, PET is valued for its recyclability. Recycled PET (rPET) is highly sought-after as it reduces environmental impact. Using rPET lowers total energy consumption and limits greenhouse gas emissions compared to using new plastic. Multiple studies have shown that PET plastic packaging has a lower environmental impact than alternatives such as aluminium and glass packaging.

PET is reusable and recyclable
PET, or polyethylene terephthalate, is a form of polyester used to manufacture plastic containers and bottles. It is a clear, durable, and versatile plastic that is 100% recyclable. Its unique properties make it highly sought after for packaging beverages, food, personal care products, and household items.
One of the key advantages of PET is its reusability. PET bottles are designed to be durable, lightweight, and flexible, allowing for repeated use. This feature aligns with the principle of reducing waste by reusing products multiple times before recycling them.
PET plastic is also highly recyclable. It can be recycled over and over again, forming a closed-loop recycling system. This process involves transforming used PET bottles or containers into new ones, retaining their value indefinitely. The simple PET recycling process includes removing labels, shredding the PET waste, and washing it. The resulting PET plastic recyclate can then be used as raw material for manufacturing various high-quality products.
The recyclability of PET has led to its widespread adoption in the beverage industry. Beverage companies recognize the environmental benefits of using recycled PET (rPET) instead of new plastic. By employing rPET, they can reduce total energy consumption by 79% and limit greenhouse gas emissions by 67%. This not only minimizes their environmental impact but also contributes to a more sustainable future.
Additionally, PET recycling is not limited to creating new bottles. Recycled PET can be utilized to produce a diverse range of products, including winter jackets, rugs, playground equipment, dog beds, and more. This versatility in recycling applications further enhances the sustainability and reusability of PET materials.
