Abstract: The present invention relates to a process for manufacturing a film comprising high amounts of microfibrillated cellulose (MFC), having haptic properties. According to the present invention, a wet web comprising MFC is formed, followed by addition of particles having an average diameter of at least 1 μm to the wet web, followed by dewatering and/or drying. The wet web may be formed for example by wet laid or cast forming methods. The particles may be added to the wet web for example by cast coating or spraying.

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.
