Disclosed is a crosslinked cellulose composite film including a regenerated cellulose matrix containing a uniform dispersion of hemp fibers and a poly(ethylene oxide) plasticizer. A method for forming the film includes mixing a slurry of the hemp, poly(ethylene oxide) and a cellulose solvent with a cellulose solution, extruding the mixture, regenerating the cellulose from the solution to form the matrix containing hemp fibers, contacting with a crosslinking agent and then drying.

Pellicule cellulosique mixte réticulée, renfermant une matrice cellulosique régénérée avec, uniformément dispersés, des fibres de chanvre et un plastifiant de poly(oxyde d'éthylène). On obtient la pellicule en mélangeant une suspension épaisse de chanvre, de poly(oxyde d'éthylène) et de solvant cellulosique avec une solution de cellulose, en extrudant le mélange, en régénérant la cellulose à partir de la solution pour former la matrice renfermant les fibres de chanvre, en la mettant en contact avec un agent de réticulation et en la séchant.
