Abstract

A method for manufacturing a cellulose product, comprising the steps: dry forming a cellulose blank in a dry forming unit; arranging the cellulose blank in a forming mould; heating the cellulose blankto a forming temperature in the range of 100 DEG C to 200 DEG C; and pressing the cellulose blank in the forming mould with a forming pressure of at least 1 MPa.

Description

technical field [0001] The present disclosure relates to methods of making cellulosic products from cellulosic fibers. The present disclosure further relates to cellulosic product forming apparatus and cellulosic products. Background technique [0002] There are many situations where it is desirable to provide flat or substantially non-flat shaped objects made of sustainable materials. A flat shape may refer to a generally two-dimensional (2D) shape, such as for example the shape of a sheet or blank, and a substantially non-flat shape may refer to any suitable three-dimensional (3D) object shape. One such case involves the packaging of liquids, dry materials and different types of goods, where the packaging can be made into three-dimensional shapes or formed from two-dimensional sheets into three-dimensional shapes. [0003] When packaging sensitive goods, such as mechanical high-precision goods, electronic devices and other household and hardware goods, protective packagi...
