    In this paper aimed to enhance the mechanical properties of an antimicrobial film by incorporating purified cellulose obtained from bamboo shoot shells into a chitosan matrix. Films with varying amounts of cellulose (0%w/v, 0.2%w/v, and 0.4%w/v) were investigated. Results indicated that the chitosan film reinforced 0.4%w/v cellulose exhibited higher tensile strength (43.50 MPa) and elongation at break (39.40 %) compared to the film without cellulose (34.47 MPa, 18.27 %). Additionally, the film with 0.4%w/v cellulose showed antimicrobial activity against B. cereus (MIC 12.5 mg/mL), S. aureus (MIC 6.25 mg/mL), E. coli (MIC 6.25 mg/mL), and exhibited 68.67 % inhibition of Fusarium oxysporum. Due to its biodegradability, favorable mechanical properties, and strong antimicrobial ability, the cellulose-chitosan film presents a promising alternative to be applied in the food industry, such as in packaging of dried food or as a coating film.
