摘要： The present invention is directed to products, such as paper and paperboard products, comprising a substrate containing a recycled cellulose-containing material and top ply comprising one or more inorganic particulate material; 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 a stage when the substrate comprising a wet web of pulp 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.

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.
