I-Polylactic acid (PLA) yi-thermoplastic aliphatic polyester.I-asidi ye-lactic okanye i-lactide efunekayo ekuveliseni i-polylactic acid inokufumaneka ngokuvutshelwa, ukuchithwa kwamanzi kunye nokuhlanjululwa kwemithombo ehlaziyiweyo.I-asidi ye-polylactic efunyenwe ngokubanzi ineempawu ezintle zoomatshini kunye nokucubungula, kwaye iimveliso ze-polylactic acid zinokutshatyalaliswa ngokukhawuleza ngeendlela ezahlukeneyo emva kokulahlwa.
