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.
