Study on forming foam trays of potato starch by adding additives to enhance the strength of the foam tray. Substances added to them is Corn fiber and polyvinyl alcohol. The study adding more fiber to make corn starch foam trays with the tensile strength and elasticity of the foam tray down. But the addition of polyvinyl alcohol will increase the tensile properties. Reduce the absorption of water, foam, powder tray more. Makes foam trays with dough strength, improved water resistance.
