Abstract

To expand the applicability of chitosan films in stretch-wrap packaging, the work aims to develop an antibacterial chitosan-based composite film with high stretch ratio and enhanced antimicrobial properties. A series of composite films were fabricated by blending chitosan with carboxylated polyvinyl alcohol (PVA-COOH) at varying ratios. The films were systematically characterized for their structural, mechanical, and antibacterial properties, followed by validation of their efficacy in preserving fresh-cut apples. The incorporation of 20% PVA-COOH facilitated the formation of ionic hydrogen bonds within the chitosan matrix, resulting in significant mechanical reinforcement. Specifically, the composite film exhibited a tensile strength of 63.38 MPa and an elongation at break of 23.93%, representing improvements of 102.04% and 274.49%, respectively, over pure chitosan film. Due to the increase in the protenation degree of -NH₂ in chitosan, the antibacterial rates of the chitosan-based composite film with a PVA-COOH content of 20% against Staphylococcus aureus and Escherichia coli were as high as 99.01% and 99.25% respectively, which were enhanced by 48.91% and 32.16% respectively compared with pure chitosan film. After 7 days of packaging preservation for cut apples, the chitosan-based composite film showed a good antibacterial packaging preservation effect. Overall, compared with pure chitosan film, the carboxylated polyvinyl alcohol-reinforced chitosan-based composite film has better mechanical properties and antibacterial performance compared with pure chitosan film, and has broader development prospects in the field of antibacterial packaging.
