ABSTRACT
Polyesters are versatile, thermoplastic, or thermoset polymers with an ester functional group. Polyesters have relevant properties, such as mechanical strength, temperature stability, barrier to gases, aromatic compounds, and water vapors, for applications in food packaging. Polyesters developed with biocomposite materials present promising and functional properties for applications in food packaging. However, packages produced with these biocomposites have poor mechanical and barrier properties. Nanofillers reinforcement emerges to improve these properties of polyester-based biocomposites. However, using polyester-based bionanocomposites in food packaging materials should be further investigated to evaluate their biocompatibility, safety, toxicity, and environmental impacts. This chapter addresses the potential of polyester-based biocomposites for food packaging development, focusing on strategies to improve their properties through nanotechnological approaches.
