Abstract: The invention discloses a paperboard comprising a base ply, a top ply, and an intermediate layer disposed in-between the at least one base ply and the top ply. The intermediate layer comprises pigment and microfibrillated cellulose (MFC). The application of an intermediate layer comprising pigment and MFC in-between the base ply and the top ply gives rise to improved optical properties of the paperboard, even when using an uncoated top ply having a low grammage. This makes it possible to reduce the grammage of top ply and still obtain good optical properties.

Abstract: The present invention is directed to a process for manufacturing a film or coating comprising high amounts of cellulosic nanomaterial. According to the present invention, a screen printing press, such as a rotary screen press, is used to create a film or coating comprising cellulosic nanomaterial. One benefit of the present process is that the suspension used in the printing process has a high dry content and high viscosity, thereby facilitating the process for manufacturing a film or coating comprising high amounts of cellulosic nanomaterial.
