ABSTRACT The invention relates to special amyloses for producing biodegradable, clear, transparent and flexible plastic, in particular sheets and films, which a) are swellable, but not soluble, in cold water; b) yield homogenous, flowable quasi-solutions without formation of gels if they are heated, with stirring, to temperatures above 80 C, at atmospheric pressure; during cooling to a temperature of 50°C, this state is maintained for at least five minutes, without gel formation or retrogradation, and the solution in a concentration between 5 and 25 % is applicable to knife coating onto a plane surface with a gap width between 100 and 700 µm.
