This study developed modified poly (butylene succinate) (MPBS) nanocomposites reinforced with ZnO nanoplate-decorated carbon nanotubes (CNT-ZNP) to improve mechanical, thermal, and functional properties for food packaging applications. MPBS was synthesized via grafting of maleic anhydride to enhance compatibility with nanofillers. Incorporation of only 0.1 g/hg CNT-ZNP led to substantial improvements in tensile strength (36.5 %), elongation at break (108.6 %), and yield strength (41.6 %), demonstrating that enhanced performance can be achieved with minimal nanofiller content. The nanocomposite also exhibited enhanced crystallinity, thermal stability, and water vapor barrier performance. Food preservation tests demonstrated that MPBS/CNT-ZNP films effectively maintained banana freshness over 14 days and inhibited microbial growth in raw chicken for up to 108 h. These outcomes highlight the material's potential to extend shelf life and reduce spoilage in perishable products. Overall, the MPBS/CNT-ZNP nanocomposites combine mechanical robustness with antimicrobial and preservation functionality, supporting their application as sustainable and multifunctional food packaging films.
