We have been selling water bottles online since May 2009. Back when we first started, bpa in hard plastics called polycarbonate were common place, especially in baby bottles. BPA is a chemical that has been scientifically proven to be an endocrine disruptor. The industry has self-regulated this chemical out of water bottles, baby bottles and most food containers, however it can still be found in thermal printed receipts and in the lining of most canned food sold in Australia.
