Abstract

The invention relates to special amyloses for the production of biodegradable, clear, transparent and flexible plastics, especially foils and films, which: (a) swell but do not dissolve in cold water, (b) produce uniform fluid quasi-solutions without gel formation on heating to above 80 DEG C with agitation, where this state is maintained on cooling to a temperature of 50 DEG C without gel formation and deterioration for at least five minutes and the solution, in a concentration of 5 to 25% can be extruded on a flat substrate with a slot width of 100 to 700 mu m.
