Application of Bagasse Cellulose Nanofibers to Make Nanocomposite Film for Food Packaging

All-cellulose nanocomposite (ACNC) film was produced from sugarcane bagasse nanofibers using N,Ndimethylacetamide/lithium chloride solvent. The average diameter of bagasse fibers (14 μm) was downsized to 39 nmafter disk grinding process. X-ray diffraction showed that apparent crystallinity and crystallite size decreased relative toan increased duration of dissolution time. Tensile strength of the fiber sheet, nanofiber sheet and ACNC prepared with10 min dissolution time were 8, 101 and 140 MPa, respectively. Water vapor permeability (WVP) of the ACNC filmincreased relative to an increased duration of dissolution time. ACNC can be considered as a multi-performance materialwith potential for application in cellulose-based food packaging owing to its promising properties (tough, bio-based,biodegradable and acceptable levels of WVP).
