Commentary
Sugar is extracted from sugarcane, corn, sugar beets, etc., and fermented to produce lactic acid, which is polymerized to form a polymer. It is finally decomposed into water and carbon dioxide by microorganisms in nature.
Key points
- Low decomposition performance compared to other biodegradable plastics, and almost no decomposition unless in a composting environment
- Adjust rigidity by alloying with PBAT, and use as biodegradable mulch film for agriculture
- Difficult to crystallization and need longer cooling temperatures in injection molding
Agricultural mulch film
