The results showed that film thickness increased with higher CA concentrations. The water activity (<i>a</i><sub>w</sub>) of the films ranged from 0.40 to 0.43. At 0.3% CA, the water solubility, water absorption, and water vapor permeability of the composite film decreased, while puncture strength and tear strength increased. However, at higher CA concentrations (0.5–0.7%), water solubility, water absorption, and vapor permeability increased, while puncture and tear strength decreased. Biodegradability tests showed that the composite films degraded by 36.84 to 53.39% for 8 weeks. When used as banana packaging, the composite film containing 0.3% CA demonstrated the highest efficiency in extending shelf life, maintaining freshness for nearly 7 days longer compared to bananas not sealed with the composite film. These findings suggest that the composite film made from CS and PVA, crosslinked with 0.3% CA, offers the most favorable overall properties-both in terms of physical and mechanical properties as well as fruit preservation potential. This highlights its promise for future development as a biodegradable polymer film for food packaging applications.</p>","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"61 4","pages":"919 - 928"},"PeriodicalIF":0.8,"publicationDate":"2026-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145963700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
