Abstract

A biopolymer blend is provided that comprises a combination of three components: poly (butylene adipate-co-terephthalate) (PBAT); agriculture sourced polylactic acid (PLA); and engineered proteinaceous eggshell nanoparticles. The two polymer components can be present in any ratio but an approximate 70:30 ratio is preferred. The engineered proteinaceous eggshell nanoparticles are preferably about 10-25 nanometers. Also provided are methods of preparing biopolymer film and packaging components. Pelleted poly (butylene adipate-co-terephthalate) and agriculture sourced polylactic acid (PLA) are dissolved in chloroform and mixed together to form a polymer blend, and engineered proteinaceous eggshell nanoparticles are incorporated into the polymer blend, which is then extruded to create a biopolymer film or component.
