The ability of cellulose nanomaterials to form non-porous films with good barrier properties has been demonstrated in numerous laboratory studies. These films can be either deposited on a pre-formed surface or directly be used as packaging material. However, the production of such films on commercial equipment presents some challenges, because of the unique properties of these high surface area materials. This proposal focuses on the production of coated barrier papers and films comprising cellulosic nanomaterials. These papers and films will be manufactured on a conventional Fourdrinier paper machine and, in some cases, coated offline. Several pilot-scale trials will be conducted during the project to optimize process parameters and determine the level of performance that can be obtained on such equipment. Results from the project will guide current efforts by the Canadian pulp and paper industry to incorporate the new cellulosic nanomaterials into paper-based products for packaging applications.
