Structural evolution and barrier enhancement of polylactide-based films via double bubble extrusion with poly(butylene adipate-co-terephthalate) and thermoplastic starch

Puntos clave

• Barrier enhancement was notably achieved, increasing the material's protective qualities without compromising flexibility.
• The study identified a 30% increase in barrier performance, measured by water vapor transmission rate.
• Analysis used double bubble extrusion to combine polylactide with poly(butylene adipate-co-terephthalate) and thermoplastic starch.
• These findings imply potential applications in sustainable packaging solutions and biodegradable materials.
