Embodiment Construction

[0064] Various aspects of the present disclosure will be described below in order to illustrate but not limit the present disclosure with reference to the accompanying drawings, in which like reference numerals refer to like elements, and variations of the described aspects are not limited to the specific illustrated embodiments, but rather Other variations of the present disclosure are applicable.

[0065] In this detailed description, a method of manufacturing a cellulose product, a pressure molding apparatus and a cellulose product will be described.

[0066] Various embodiments of sheets or blanks according to the present disclosure are discussed primarily with reference to a cellulosic blank placed in a flat shape for forming in a forming die. It should be noted that this in no way limits the scope of the invention, which also includes, for example, blanks preformed into three-dimensional objects. For example, a blank may be presented to a forming die in a shape similar ...

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...
