Abstract: The invention relates to systems and techniques for manufacturing articles containing cellulosic material, a coupling agent, and a binder resin, and related processes of making and using the cellulosic articles. In particularly exemplary embodiments, the manufactured articles are door skins, sometimes known as door facings, and doors made from the door skins. The article contains a lipophilic cellulosic material, a coupling agent, and a binder. The coupling agent is believed to increase the hydrophilicity (wettability) of the lipophilic cellulosic material.

Abstract: A biopolymer film is provided that comprises a combination of: crystalline nano cellulose (CNC)/esterified crystalline nano cellulose (ECNC) reinforced with chitosan. The two polymer components can be present in any ratio but an approximate CNC to ECNC 70:30 ratio is preferred. The chitosan component is derived from exoskeletons of crustaceans. Also provided are methods of preparing biopolymer film and preparing food packaging components from said biopolymer film. The CNC/ECNC mixture is dissolved in an ethanol solution and the chitin is dissolved in acetic acid and mixed together to form a polymer blend.
