Cellulose and cellulose ester film
A film is made from a wet laid product containing cellulose fibers and cellulose ester fibers and a plasticizer. The film can be made by heat pressing the wet laid sheet to form a film having a continuous phase of cellulose ester resin and a discontinuous phase of cellulose fibers.

METHOD, APPARATUS, AND SYSTEM OF A FIBRILLATED NANOCELLULOSE MATERIAL
Embodiments of the invention overcome the shortcomings of prior technologies by infusing nanocellulose in a fibrillated form to enhance the properties of cellulose pulp. These properties may include, for example, the mechanical and barrier properties, i.e., tensile strength, liquid, and gas impermeability such as oxygen, carbon dioxide, and oil, may be improved substantially. Another embodiment of the invention further provide a fibrillated cellulose composite material that include properties of being a strength-enhancing agent, an oligomer, carboxylic acid, plasticizer, an antimicrobial agent, water repellant, and/or a transparent composite.

Sheet manufacturing apparatus and control method for sheet manufacturing apparatus
A defibrating unit that defibrates a raw material including fibers in an atmosphere, an accumulating unit that discharges defibrated matter by rotating a drum unit in which a plurality of openings are formed, a second web forming unit that forms a second web by operating a mesh belt on which the defibrated matter is accumulated, a sheet forming unit that forms a sheet from the second web, a cutting unit that cuts the sheet into a preset size, and a control unit that executes a stop control with a cut operation of the cutting unit as a trigger in a case where an instruction to stop an apparatus is provided are included. In the stop control, the control unit stops operation of the defibrating unit after stopping rotation of the drum unit and movement of the mesh belt.
