It means that Bisphenol (A) is not present.
BPA is an industrial chemical that is used to produce some chemicals and resins. Some research has shown that BPA can enter into food or beverages from containers that are manufactured with BPA. Exposure to BPA is a serious issue because of possible health problems caused by BPA on the brain, behavior and prostate gland of fetuses, infants and children (Mayo Clinic, 2016)Another research suggests that there is a possible link between BPA and increased blood pressure.Therefore, people choose to use BPA free products to keep their health in good condition. I commonly use this term no exposure means no impact.According to the Mayo Clinic (2016):Use BPA-free products. Manufacturers are creating more and more BPA-free products. Look for products labeled as BPA-free. If a product isnt labeled, keep in mind that some, but not all, plastics marked with recycle codes 3 or 7 may be made with BPA.
