What is polyethylene terephthalate (PET, PETE)?
Polyethylene terephthalate (PET) is clear, tough, and shatterproof. It provides a barrier to oxygen, water, and carbon dioxide and is identified with the number 1. PET’s ability to contain carbon dioxide (carbonation) makes it ideal for use in carbonated soft drink bottles. Take a look at the bottom of your soft drink bottle and you will most likely find a number 1 there. PET is also used to make bottles for water, juice, sports drinks, beer, mouthwash, catsup, and salad dressing. You can also find it on your food jars for peanut butter, jam, jelly, and pickles as well as in microwavable food trays. According to the American Chemistry Council, PET has been approved as safe by the FDA and the International Life Sciences Institute (ILSI). In 1994, ILSI stated that “PET polymer has a long history of safe consumer use, which is supported by human experience and numerous toxicity studies.” The American Chemistry Council cautions that products made with PET be used only as indicated by the m
