Polylactic acid (PLA) imhando nyowani yebio-based uye inogona kuvandudzwa biodegradable material, iyo inogadzirwa kubva kune sitarch mbishi zvinhu zvinokurudzirwa nezvinogadzirwazve chirimwa zviwanikwa (sechibage, mufarinya, nezvimwewo).Starch raw material inosaccharified kuti iwane glucose, yobva yaviriswa kubva kuglucose uye mamwe madhiri kuburitsa yakakwira-kuchena lactic acid, uyezve kemikari synthesis nzira inoshandiswa kugadzira polylactic asidhi nehumwe huremu hwemamorekuru.Iine biodegradability yakanaka, uye inogona kuderedzwa zvachose nehutachiona mumasikirwo pasi pemamiriro ezvinhu chaiwo mushure mekushandiswa, pakupedzisira ichigadzira carbon dioxide nemvura, pasina kusvibisa zvakatipoteredza, iyo inobatsira zvikuru pakudzivirira zvakatipoteredza uye inozivikanwa sechinhu chinochengetedza zvakatipoteredza.
Polylactic acid ine yakanaka kugadzikana kwekupisa, tembiricha yekugadziridza i170 ~ 230 ℃, uye ine yakanaka yekunyungudutsa.Inogona kugadziriswa nenzira dzakasiyana-siyana, senge extrusion, spinning, biaxial kutambanudza, uye jekiseni blow molding.Pamusoro pekuve biodegradable, zvigadzirwa zvakagadzirwa nepolylactic asidhi zvine biocompatibility yakanaka, kupenya, kujeka, kunzwa kwemaoko uye kudzivirira kupisa, pamwe nekumwe kupikisa mabhakitiriya, kudzoreredza kwemoto uye UV kuramba, saka anobatsira zvikuru.Inoshandiswa zvakanyanya semidziyo yekurongedzera, fiber uye nonwovens, nezvimwewo, parizvino inonyanya kushandiswa muzvipfeko (yemukati, zvipfeko zvekunze), indasitiri (kuvaka, kurima, masango, kugadzira mapepa) uye minda yekurapa nehutano.
