Abstract: The increasing demand for sustainable packaging solutions has driven research into biodegradable and renewable materials as alternatives to conventional petroleum-based plastics. Palm fiber, an abundant agricultural waste product, presents a promising candidate for sustainable packaging due to its biodegradability and mechanical strength. This study explored the development of a composite material using palm fibers and polylactic acid (PLA) for food packaging applications. By utilizing 3D printing technology, this research aimed to optimize the mechanical properties and antimicrobial efficacy of palm fiber-PLA composites, addressing both environmental concerns and food preservation challenges. The study evaluated the structural integrity and microbial resistance of the composites, specifically against Salmonella typhimurium, Staphylococcus aureus, and Escherichia coli, positioning them as viable alternatives for sustainable food packaging. The findings may contribute to reducing plastic waste while promoting environmentally responsible practices in the packaging industry.
