摘要： Provided are barrier films, packaging products including barrier films, and methods of making paper/packaging products including barrier films. The barrier films can have antimicrobial properties and can include nanofibrillated cellulose treated with hemp extractives. The nanofibrillated cellulose can be obtained from autohydrolysed hemp pulp. The antimicrobial packaging products or paper products can be made by obtaining pulp fibers from autohydrolyzed hemp hurds, mechanically grinding the pulp fibers to obtain nanofibrillated cellulose, solvent casting the nanofibrillated cellulose films in an aqueous system, treating the nanofibrillated cellulose films with hemp extractives, and applying the hemp extractive treated films to a substrate.
