Polylactic acid (PLA) ke mofuta o mocha oa lintho tse bolang le tse ka nchafatsoang, tse entsoeng ka thepa e tala ea starch e hlahisitsoeng ke mehloli ea limela e ka nchafatsoang (joalo ka poone, cassava, joalo-joalo). Lintho tse tala tsa starch li saccharified ho fumana tsoekere, ebe li belisoa ho tsoa ho tsoekere le mefuta e itseng ho hlahisa lactic acid e phahameng, ebe mokhoa oa ho kopanya lik'hemik'hale o sebelisoa ho kopanya acid e polylactic ka boima bo itseng ba molek'hule. E na le biodegradability e ntle, 'me e ka senyeha ka ho feletseng ke likokoana-hloko tsa tlhaho tlas'a maemo a itseng ka mor'a ho sebelisoa, qetellong e hlahisa carbon dioxide le metsi, ntle le ho silafatsa tikoloho, e leng molemo haholo bakeng sa ho sireletsa tikoloho le ho nkoa e le boitsebiso bo sa senyeheng tikoloho.
Polylactic acid e na le botsitso bo botle ba mocheso, mocheso oa ho sebetsa ke 170 ~ 230 ℃, 'me e na le khanyetso e ntle ea solvent. E ka sebetsoa ka mekhoa e fapaneng, joalo ka extrusion, spinning, biaxial stretching, le ente blow molding. Ntle le ho senyeha ha lintho, lihlahisoa tse entsoeng ka polylactic acid li na le biocompatibility e ntle, gloss, ponaletso, maikutlo a matsoho le ho hanyetsa mocheso, hammoho le ho hanyetsa libaktheria tse itseng, ho thibela lelakabe le ho hanyetsa UV, kahoo li molemo haholo. E sebelisoa haholo joalo ka thepa ea ho paka, likhoele le li-nonwovens, joalo-joalo, tse sebelisoang haholo liphahlong (liaparo tsa ka hare, liaparo tsa ka ntle), indasteri (kaho, temo, meru, ho etsa pampiri) le masimong a bongaka le a bophelo bo botle.
