    摘要: The invention relates to special amyloses for producing biodegradable, clear, transparent and flexible plastic, in particular sheets and films, whicha) 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.degree. C., at atmospheric pressure; during cooling to a temperature of 50.degree. 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 .mu.m.
