Whether you're ordering new plastic containers for your restaurant kitchen or new water bottles for personal use, you've probably seen products that boast "BPA free!". But what is BPA? And is it necessary to avoid it?BPA stands for bisphenol A, a chemical that has been used in the manufacture of polycarbonate plastics and resins since the 1950s. Concerns about this chemical began in the 1990s when customers began asking, "Is BPA safe?" Since then, several studies have attempted to link BPA to health problems, but the FDA has concluded that low levels of BPA exposure are not harmful to humans. Nonetheless, the U.S. and Canada have banned the use of BPA-containing baby bottles to prevent potentially negative effects on children, and many companies have voluntarily phased out BPA-containing adult water bottles in an effort to reassure worried consumers.

What plastics contain BPA?

While a certain amount of BPA is safe for humans to ingest on a daily basis, consumers should be aware of which plastics contain BPA and other potentially harmful chemicals. Plastics are categorized by resin codes that tell consumers how to recycle different types of plastics. The recycling numbers also correspond to the chemicals used to actually make the plastic. Keeping these numbers correct can be difficult, so this list will help you figure out which plastics are safe to use in a variety of different situations.
