What does bpa-free mean?


assistant
BPA-Free refers to any plastics or other materials that do not contain any traces of Bisphenol-A.  Most plastics including bottled waters use BPA-Free plastic because it has been shown when BPA plastics are exposed to heat that the BPA chemicals can leach into liquids and into food which people then ingest.
