Bisphenol A (BPA) Overview & Updates. BPA (Bisphenol A) is a chemical used in certain food contact materials and first approved by FDA in the early 1960s. In recent years, concerns have been raised about BPA's safety. In August 2008, FDA released a draft report finding that BPA remains safe in food contact materials.
BPA is a chemical component present in polycarbonate plastic used in the manufacture of certain beverage containers and most food can liners. BPA-based plastic bottles are clear and tough. In cans, BPA-based liners form a barrier between the food and the can surface that prevents corrosion of the can and migration of metal into the food.
