Cellulose Nanofibrils (CNF) are a biorenewable, biodegradable nanomaterial of good properties.  However, it is usually processed like paper leading to higher costs.  Here we show that CNF can be processed more like polymer melts and due to its nano nature can have similar properties, to boot. CNF sheets can be extruded at greater than 1 mm thick with tensile strengths of &gt;150 MPa and modulus of &gt;10 GPa. The rheology necessary also is amenable to molding operations.  Here, we will describe efforts at applying moldable CNF to direct molding to produce objects. Further, progress at in-mold coating and sheet-molding lamination onto molded pulp containers will be described. Molding/coating quality, WVTR, strength and other properties will be discussed.  Lidding of the containers is also reported and provides and avenue for a fully biobased sealed package.
