Zusammenfassung:	The disclosure relates to a method for producing nanocellulose films, as well as nanocellulose films produced by such a method. The method comprising the steps:a) providing a gellable nanocellulose dispersion comprising a nanocellulose and water, wherein the gellable nanocellulose dispersion comprises from about 0.1 weight% to about 5 weight% total dry matter relative to the total weight of the gellable nanocellulose dispersion, and wherein the nanocellulose constitutes from about 10 weight% to about 100 weight% of the total dry matter;b) extruding the nanocellulose dispersion through an extrusion die into a coagulation liquid to provide a strip of nanocellulose gel; andc) removing water from the strip of nanocellulose gel to provide a nanocellulose film.
