"Part of the yogurt eating ritual has always been licking the food off the foil lid. Over the course of a year, the yogurt stuck to lids worldwide is equivalent to the volume consumed in Africa, according to a calculation by Toyo Aluminium. Morinaga Milk Industry is doing something about that: Its lids peel off clean with no stuck yogurt. The company uses a special lid developed in cooperation with Toyo Aluminium. It is based on a packaging technology Toyo calls "Toyal Lotus." The material's structural inspiration was the lotus leaf, which is famous for its ability to shed water and remain dry."
