摘要： The invention relates to a process and an apparatus for producing a molded fiber article. The process comprises the steps of —dissolving fibrous materials in water to form a fibrous material suspension in a pulper, —removing moisture from the fibrous material suspension by pressing to form a molded fiber article in a mold and/or —drying the molded fiber article by supplying heat, —demolding the molded fiber article from the mold. The process is characterized by the feature whereby, in mold drying of the molded fiber article in the mold, a moisture content of the molded fiber article of not more than 10% by weight or not more than 7.5% by weight or not more than 5% by weight is achieved.

摘要： The present invention relates generally to the field of three-dimensional cellulose-based objects, for example cellulose base packaging materials. In particular, the present invention relates to molded cellulose-based objects with a functionalized surface, for example a surface that reduces water absorption. One embodiment of the present invention relates to a molded cellulose-based object comprising a cellulose gel layer. For example, the cellulose gel layer may be obtained by sulfurization.
