Zusammenfassung:The invention relates to a fibrous web product such as paper, and a method for the preparation of such fibrous web. According to the method microfibrillated cellulose (MFC) together with a pulp of a greater fiber length, such as chemithermomechanical pulp (CTMP), are mixed with a foam of water and a sur-factant, the foam is supplied to a forming fabric of a paper or board machine, dewatered by suction of air through the forming fabric, and dried to the final web product. The method brings a high bulk in combination with a high Scott bond value, to provide improved wet and dry tensile strength for the paper and board products.
