Abstract

The growing environmental concerns associated with conventional petroleum-based plastics have accelerated the search for sustainable alternatives for packaging applications. Biodegradable polymer nanocomposites have emerged as promising materials due to their eco-friendly nature, enhanced mechanical properties, and reduced environmental impact. This study focuses on the sustainable synthesis of biodegradable polymer nanocomposites designed for advanced packaging applications. Biodegradable polymers, including polylactic acid (PLA) and starch-based matrices, were reinforced with environmentally benign nanofillers such as cellulose nanocrystals and nanoclays using green processing techniques. The synthesized nanocomposites were characterized for their structural, mechanical, thermal, barrier, and biodegradation properties. Results demonstrated that the incorporation of nanoscale fillers significantly improved tensile strength, thermal stability, and resistance to moisture and gas permeation compared to neat biodegradable polymers. Enhanced barrier properties are particularly advantageous for food packaging, where protection against oxygen and moisture is essential for extending shelf life. Biodegradation studies revealed that the developed nanocomposites maintained their environmental compatibility while exhibiting controlled degradation under composting conditions. Furthermore, the sustainable synthesis approach minimized the use of toxic solvents and reduced energy consumption during production. The findings suggest that biodegradable polymer nanocomposites synthesized through environmentally responsible methods offer a viable alternative to conventional packaging materials. Their combination of performance, sustainability, and biodegradability highlights their potential for next-generation packaging solutions that support circular economy principles and environmental conservation.
