Abstract

In recent years, nanomaterials have attracted great interest in food packaging due to their unique properties. Nanoscale titanium dioxide, recognized for its excellent biocompatibility, photocatalytic, and antibacterial properties, is considered a functional nanofiller in biodegradable food packaging films. This paper introduces the preparation method of nano-TiO₂ composite films, analyzes the diverse functions of the composite films in UV shielding, antibacterial activity, ethylene removal, and smart response, summarizes the latest research progress of nano-TiO₂ composite films widely used in the preservation of fruits, vegetables, and meat packaging, discusses the safety hazards of nano-TiO₂ in food packaging, and prospects its development, aiming to provide theoretical references and new insights for the future research on functional and intelligent food packaging in the field of nano-TiO₂ composite films.
