Method for manufacturing cellulose product by pressure moulding apparatus, pressure moulding apparatus and cellulose product

Abstract

The present invention relates to a method of manufacturing a cellulose product having a flat or non-flat product shape by a pressure moulding apparatus comprising a forming mould. The forming mould has a forming surface defining the product shape, The method comprises the steps of: arranging a cellulose blank containing less than 45 weight percent water in the forming mould; heating the celluloseblank to a forming temperature in the range of 100 to 200 degrees centigrade; and pressing the cellulose blank by means of the forming mould with a forming pressure acting on the cellulose blank across the forming surface, the forming pressure being in the range of MPa to 100 MPa.

Description

technical field [0001] The present disclosure relates to methods of making cellulosic products from wood pulp, equipment for making such cellulosic products and cellulosic products. Background technique [0002] There are many situations where it is desirable to provide two-dimensional (2D) or three-dimensional (3D) shaped objects made of sustainable materials. One such situation involves the packaging of sensitive goods, such as mechanical high-precision goods, electronic equipment and other household and hardware goods, which require protective packaging to avoid damage caused by, for example, mechanical shock, vibration or compression during transport, storage or other handling. The damage caused by sensitive goods. Such packages generally require a protective insert that is shaped to accommodate the goods contained therein and thus hold the goods securely in the package. Such inserts are typically made from expanded polystyrene (EPS), which is a lightweight petroleum-d...
