Abstract:The antibacterial packaging film based on starch and polyvinyl alcohol has good antibacterial and biodegradable properties, and has become a current research hotspot in the field of active packaging. However, it has some problems such as insufficient mechanical properties, poor water resistance, migration of antibacterial agents, and poor environmental adaptability, which limit its application in food and medicine. The research progress on the influence of starch type and polyvinyl alcohol modification on the comprehensive performance of antibacterial packaging films were introduced, and the controlled release mechanism and methods of antibacterial active ingredients in antibacterial packaging films and the application of antibacterial packaging film based on starch and polyvinyl alcohol in the storage and preservation of fruits, vegetables, and meat products were elaborated in this article. Intelligent active packaging materials have broad development prospects. In the future, research on multifunctional composite antibacterial packaging materials will help improve the indicative, stable, and slow-release control properties of antibacterial packaging films, which are conducive to the sustainable development of the packaging industry and provide new strategies for the application of green packaging materials in the food and pharmaceutical fields.
