Abstract: A method of manufacturing a security paper is presented. The method comprises: preparing a composition A containing a mixture of softwood and hardwood pulp, and preparing a mixture β of a refined pulp and magnetic wires having predetermined magnetic properties; preparing a composition C by blending the mixture B and the composition A; diluting the composition C, and forming a pulp single layer D including the magnetic wires at a predetermined density; removing moisture from the pulp single layer D; forming at least one protective coating layer on at least one side of the paper; and calendering the paper, thereby obtaining a security paper structure with the magnetic wires fully embedded in the pulp single layer.

Abstract: A composition is contained a blend zone prior to refining containing non-fibrillated virgin cellulose fibers, waste/recycle cellulose fibers or both; cellulose ester fibers, water, and one or more additives comprising fillers, internal sizing agents, biocides, process anti-foaming agents, colorants, optical modifiers, or a combination thereof. An in-line mixer can be used for adding the additives, and the consistency of the composition is lowered relative to a feed of material from a hydropulper.

Abstract: A process is disclosed for making paper having improved filler retention and opacity. The process includes the step of adding Additive A and Additive B to a slurry in a wet end of a paper machine wherein the slurry comprises pulp and a filler. Additive A is a wet strength agent. Additive B is an anionic polymer having a charge density from about −3000 to about −7000 ueq/g on a dry basis when measured in a buffer having a pH of about 6. Additive B also has a weight average molecular weight of from about 150,000 to about 1,000,000, Daltons.

Abstract: 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.
