You can be assured that polypropylene material used in the manufacture of our products does not have BPA (Bisphenol A) in it; it is not added into the formulation. BPA is used in the manufacture of polycarbonate (a completely different material) which is used predominantly in plastic corrugated sheet roofing and drink ware. Since the BPA issue came to light a number of years ago, manufacturers of drink ware now use a different type of clear material.
