Recent advances in packaging materials for food products

Abstract The food industry is adapting to evolving consumer demands for “healthy” and premium quality food by reducing the adverse effects of food packaging through innovative advancements in active and intelligent packaging technologies. These smart innovations offer diverse and creative ways to enhance food product quality and safety while extending shelf life. Emerging techniques are also improving the passive aspects of food packaging systems, such as thermal stability, barrier effectiveness, and mechanical strength. Notably, the use of plants, biodegradable materials, and nanomaterials in sustainable food packaging helps mitigate its negative environmental impact. By integrating intelligent, environmentally friendly, and active packaging technologies, a multipurpose food packaging system can be developed that maintains the integrity of all its components, representing the pinnacle of technological advancement in food packaging. This article reviews the fundamentals of food packaging systems, recent advancements in various packaging techniques, commercialized patents, future research trends, and the challenges that need to be addressed in food packaging.
