METHOD FOR MANUFACTURING A FILM COMPRISING HIGHLY REFINED CELLULOSE FIBERS

The present invention relates to a method for manufacturing a film comprising highly refined cellulose fibers in a paper-making machine, the method comprising the steps of: a) providing an aqueous pulp suspension comprising at least 20% by dry weight of highly refined cellulose fibers having an SR (Schopper-Riegier) value in the range of 80-100 at a consistency in the range of 0.8-3 wt % and; b) deflocculating and diluting the aqueous pulp suspension to a lower consistency in the range of 0.1-1.5 wt % by injecting the aqueous pulp suspension into an aqueous stream using a high shear mixer to obtain a diluted aqueous pulp suspension; and c) feeding the diluted aqueous pulp suspension to a headbox of the paper-making machine.
