PET Plastic Bottles: What Is It?

PET stands for polyethylene terephthalate, a form of plastic resin and polyester. Polyethylene terephthalate is a polymer composed of modified ethylene glycol and purified terephthalic acid.

Why should I care?

We use PET containers in our daily lives, whether it's making sandwiches or buying bottled water from a store. PET is a plastic with the #1 code affixed to or near the bottom of bottles and containers. It is commonly used for packaging soft drinks, water, juice, peanut butter, salad dressing and oil, cosmetics, and household cleaners.

Manufacturers use PET plastic to package products because of its strength, thermal stability, and transparency. Customers choose PET because it is cheap, lightweight, resealable, shatter-resistant, and recyclable. Recycled polyethylene terephthalate (RPET) can be used to make many new products, including polyester carpet fibers; fabrics for t-shirts, shoes, suitcases, etc.

Why do soda and bottled water companies use PET bottles instead of glass?

PET is hygienic, strong, resistant to microbial attack, does not react with food or beverages, and does not biodegrade. The safety of its food and beverage use has been recognized by health authorities around the world. But unlike glass, PET is very light, easy to transport, and will not break, which is why it is the preferred packaging for many food and beverages.

Will a PET bottle placed in a hot car or in a microwave release dioxins?

Do not. PET does not contain dioxins, nor does it produce dioxins, nor does it produce dioxins during the PET production process. Dioxins are a group of compounds that are sometimes formed by high-temperature combustion (over 750 degrees Fahrenheit) and certain industrial processes involving chlorine. Dioxins cannot be produced without the presence of chlorine, and PET does not contain chlorine. Therefore, when the PET container is heated or microwaved, exposed to sunlight, or washed and reused (all urban myths), dioxins will not be produced.

In short, using PET plastic is a healthier way to preserve and store our food and liquids, which is why we use PET plastic. Be sure to check the #1 triangle label! In addition, consumers should be aware that once opened, any packaging material may breed bacteria if the food or beverage is stored under conditions suitable for bacterial growth. Therefore, it is best to wash any containers with hot soapy water and dry them thoroughly before use.
