Active, smart, and intelligent packaging focuses on innovative strategies to enable food preservation, freshness, easy detection, quality control, and health standards in the global packaging market. Moreover, various types of components applied in food wrapping are non-biobased and cannot satisfy society’s expanding demands for sustainability and environmental protection. Sustainability is a worldwide aspiration that addresses societal challenges such as environment, raw materials, resource efficiency, climate protection, etc. The application of non-biobased materials in led packaging creates environmental issues. Furthermore, rising environmental problems have put packaging under intense scrutiny owing to the ongoing source of huge quantities of plastic waste. Bio-based polymer nanocomposites were recently developed to address these issues using nanoparticles with excellent performance. Finally, this chapter briefly discusses the possibilities for sustainable materials in the 21st century in diverse packaging applications.
