Material	90 % Starch
	Usually referred to as thermoplastic starch. They are stable in oils and fats, however, depending on the type, they can vary from stable to unstable in hot/cold water. They can be processed by traditional techniques for plastics. These materials consist mainly (>90%) of starch obtained from renewable natural sources. Colouring and flame retardant additives are possible.
