I-Polylactic acid (i-PLA) luhlobo olutsha lwe-bio-based kunye ne-biodegradable material ehlaziyiweyo, eyenziwa kwi-starch imathiriyeli ekrwada ecetywayo yimithombo yezityalo ezivuselelekayo (ezifana nombona, i-cassava, njl.).Isitashi izinto ekrwada ekrwada ukufumana iswekile, kwaye ke igwele ukusuka iswekile kunye neengxaki ezithile ukuvelisa i-asidi lactic obusulungekileyo, kwaye ke indlela imichiza synthesis isetyenziselwa synthesis i-polylactic acid kunye nobunzima ethile molecular.Ine-biodegradability elungileyo, kwaye inokutshatyalaliswa ngokupheleleyo yi-microorganisms kwindalo phantsi kweemeko ezithile emva kokusetyenziswa, ekugqibeleni ivelise i-carbon dioxide kunye namanzi, ngaphandle kokungcolisa imo engqongileyo, enenzuzo kakhulu ekukhuseleni okusingqongileyo kwaye ibonwa njengento ehambelana nokusingqongileyo.
Iasidi yePolylactic inozinzo oluhle lwe-thermal, ubushushu bokusebenza yi-170 ~ 230 ℃, kwaye inokumelana nokunyibilikisa okulungileyo.Inokucutshungulwa ngeendlela ezahlukeneyo, ezinje nge-extrusion, i-spinning, i-biaxial stretching, kunye ne-injection blow blowing.Ukongeza kwi-biodegradable, iimveliso ezenziwe nge-polylactic acid zine-biocompatibility efanelekileyo, i-gloss, i-transparency, ukuvakalelwa kwesandla kunye nokumelana nobushushu, kunye nokumelana neebhaktheriya ezithile, i-flame retardancy kunye nokumelana ne-UV, ngoko ziluncedo kakhulu.Isetyenziswa kakhulu njengezinto zokupakisha, iifayibha kunye nee-nonwovens, njl., okwangoku zisetyenziswa ikakhulu kwimpahla (impahla yangaphantsi, impahla yangaphandle), ishishini (ukwakha, ezolimo, amahlathi, ukwenza iphepha) kunye nezonyango kunye nezempilo.
