The escalating environmental concerns associated with synthetic plastics have steered the scientific community towards the development of biodegradable polymers such as poly(lactic acid) (PLA), polyhydroxyalkanoates (PHA), poly(butylene adipate-co-terephthalate) (PBAT), along with naturally-derived biopolymers including polysaccharides, lipids, and proteins. These biodegradable materials can be obtained from renewable resources and are engineered to degrade into non-toxic byproducts under appropriate environmental conditions, addressing critical issues of sustainability in materials science. The integration of bioactive compounds from natural sources like essential oils and plant extracts has further enriched the functionality of these biocomposites by providing enhanced barrier properties, and antioxidant and antimicrobial effects, which are crucial for extending food shelf life and ensuring safety.

This Research Topic aims to delve into the most recent progressions in biodegradable packaging materials that cleverly amalgamate natural and nanotechnology-based additives to bolster food preservation efforts. It intends to spotlight pioneering research in crafting innovative packaging solutions which not only align with sustainability benchmarks but also cater to the stringent needs for quality and longevity in food products. By incorporating elements such as nanoparticles, which can markedly elevate mechanical, thermal, and barrier properties, this research topic endeavours to bring forward designs that fulfill both functional requirements of food packaging and the overarching environmental protection principles.

To congregate comprehensive insights on this subject, the scope of this research encompasses a wide range of linked areas. We welcome scholarly contributions that:

- Investigate the physical and chemical properties of various food packaging materials.
- Explore functionalized or responsive composite materials suitable for packaging applications.
- Evaluate different packaging systems including polymer, glass, metal, and papers.
- Discuss the development and impact of active, intelligent, and antimicrobial packaging systems.
- Analyze microbial stability across different stages from food storage to transportation.
- Examine broader applications of these composites in food, pharmaceutical, and cosmetic industries.

Through these investigations, the goal is to foster advancements that lead to fully biodegradable or compostable packaging solutions, thus supporting the circular economy and addressing sustainability challenges associated with food packaging.
