Traceable biodegradable packaging materials combining packaging design with green environmental protection

In packaging material research, insufficient attention has been paid to biodegradable and traceable materials. This paper aims to explore the environmental friendliness and application potential of traceable biodegradable packaging materials. This paper modified polylactic acid (PLA) with talc and calcium carbonate (particle size less than 10 microns) at a 20% addition ratio. A traceability system based on Hyperledger Fabric was constructed to enhance transparency, and a life cycle assessment was conducted using SimaPro software. Experimental results showed that the modified PLA exhibited good degradation properties in soil and compost environments, good mechanical and thermal properties, and a total energy consumption of 7.95 MJ and total greenhouse gas emissions of 6.34 kg CO2e over its entire life cycle. These results demonstrate the environmental friendliness of the modified PLA in practical applications and provide new perspectives for future packaging material design, which will contribute to the industry's environmentally friendly development.
