摘要： Methods of making a paper or board product comprising a top ply slurry comprising microfibrillated cellulose and, optionally, one or more inorganic particulate material, applied to a forming web of paper through an applicator comprising a channel terminating in a slot, wherein the slot is in fluid communication with a flexible blade suitable to form a top ply on top of the forming web of paper at the wet end of the paper machine and applicators for practicing such methods.

摘要： The present invention is directed to products, such as paper and paperboard products, comprising a substrate containing cellulose and top ply comprising microfibrillated cellulose and inorganic particulate, to methods of making such paper and paperboard products, and associated uses of such paper and paperboard products. The microfibrillated cellulose and inorganic particulate material are applied at the stage when the wet substrate is in the process of being formed on the wire of a papermaking machine, thereby avoiding the additional cost of more extensive equipment and machinery as well as in separate drying of a coating. The microfibrillated cellulose facilitates the application of inorganic particulate onto the surface of a wet paper or paperboard substrate when applied thusly, by trapping the inorganic particulate on the surface of the substrate and by giving the composite sufficient strength and a suitable pore structure to make it suitable for printing and other end-use demands.

摘要： A paper product may include high energy thermomechanical pulp (TMP), low energy TMP, and microfibrillated cellulose. The paper product may also include inorganic particulate material. A papermaking composition suitable for making the paper product, a process for preparing the paper product, and use of microfibrillated cellulose may include high energy TMP, low energy TMP, and microfibrillated cellulose, and optionally inorganic particulate material. The microfibrillated cellulose may have a fiber steepness of from about 20 to about 50 in the paper product.
