    Abstract: The invention relates to a method of manufacturing a shaped tray or plate of fibrous material. The method comprises the steps of(i) providing a fibrous pulp, in which the fibres substantially consist of at least 85 wt-% of softwood fibres having an average fibre length of at least 2.0 mm and at most 15 wt-% of broke having a fibre length of about 0.05 mm to 1.0 mm, (ii) turning the pulp into a foamed suspension, (iii) supplying the foamed suspension from a headbox to a forming fabric of a board machine to form a fibrous web, (iv) drying the web to obtain a dried web having a compressibility in the thickness direction of at least 20 %, and(v) including the web as a layer in a board, which is turned to said tray or plate by thermopressing or deep-drawing. The invention even covers shaped trays and plates produced by use of the method.
