Paragraph starter

Research indicates that thermoplastic blends incorporating albumin and zein proteins, such as those combined with LDPE, demonstrate promising biodegradability. Albumin-based components degrade completely within two months in soil burial tests, while zein-based materials show more resilience. This suggests a viable route for developing more environmentally friendly food packaging solutions that reduce persistent waste.
