Abstract:
The global increase in environmental pollution caused by non-biodegradable packaging and printing\r\nmaterials has prompted significant research into biodegradable polymers. These eco-friendly\r\npolymers offer an alternative to conventional plastics, providing similar mechanical and barrier\r\nproperties while minimizing environmental impact. This paper explores the development,\r\ncharacterization, and application of biodegradable polymers in packaging and printing substrates.\r\nEmphasis is placed on materials such as polylactic acid (PLA), polyhydroxyalkanoates (PHA),\r\nstarch-based polymers, and cellulose derivatives. The study examines processing techniques,\r\nmaterial properties, biodegradation mechanisms, and performance in industrial applications. The\r\nresults indicate that biodegradable polymers can achieve comparable functional performance to\r\ntraditional polymers while reducing ecological footprints. Challenges such as cost, processing\r\nlimitations, and industrial-scale implementation are discussed. The paper concludes that integrating\r\nbiodegradable polymers in packaging and printing industries is both feasible and critical for\r\nsustainable material management.
