Used primarily in biodegradable plastics and environmentally friendly packaging materials due to its ability to break down under composting conditions. Commonly applied in agricultural films, mulch films, and disposable bags where controlled lifetime and reduced environmental persistence are required. Also utilized in controlled-release formulations for agrochemicals and pharmaceuticals, where the ester linkages allow gradual degradation and release of active ingredients. Its flexibility and film-forming properties make it suitable for coatings and laminates in short-life consumer products. Increasingly adopted in 3D printing filaments designed for compostable prototypes and educational models.
