Beschreibung
Zusammenfassung:	A three dimensional molded object comprising a mixture of cellulose fibers and microfibrillated cellulose, and optionally one or more inorganic particulate material, wherein the microfibrillated cellulose is present in an amount of about 0.5 wt. % to about 50 wt. % on a dry weight basis of the total dry mass of the mixture of cellulose fibres and microfibrillated cellulose, and optionally one or more inorganic particulate material; wherein the coarsely microfibrillated cellulose comprises less than about 90 wt. % fines and/or less than 75% fines A, and a length-weighted median length Lc(w) of greater than 0.3 mm, as measured by fibre image analyzer, and wherein the microfibrillated cellulose optionally has a fibre steepness of about 20 to about 50, as measured by Malvern Mastersizer.
