The only kind of plastic food-storage containers that contain BPA are those made with polycarbonate, which is indicated by a #7 in the recycling triangle on the bottom. But not all #7 plastic is polycarbonate. For example, Nalgene’s latest BPA-free bottles are made of copolyester plastic that contains no bisphenol A, but they still fall into the category of #7 plastics. If you are unsure, call the manufacturer.
