Abstract
A method for producing starch films comprises the following steps: preparing a mixture comprising starch and water, wherein more than 50 weight percent of the starch is present in the form of particles of granular starch; shaping the mixture to form a film in a shaping process; solidifying the mixture by increasing the temperature of the mixture during and/or after the shaping process by more than 5° C. Films produced by this method have starch particles bonded to one another. A device for performing this method comprises a shaping device for enabling shaping of the starch material to form a film, and has a heating device for performing a heat treatment for destructuring of the starch during and/or after the shaping.
