Recent Progress in Indicator Films and Their Applications in Intelligent Food Packaging

Abstract

Food packaging film, as an integral part of the food industry, plays an important role in maintaining food quality, extending shelf life, and ensuring food safety. With the upgrading of consumer demands and the growing awareness of environmental protection, traditional packaging films are gradually evolve toward functionalization, greening, and intelligent design. In the present work, visualization tools are employed to analyze the research hot spots and development trends of intelligent packaging film in recent years. Subsequently, the classification, performance, applications, and future prospects of food packaging films are summarized. These findings broaden the scope for the research and application of films in food packaging. Furthermore, with the integration of materials science and
