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 iasidi lactic obusulungekileyo, kwaye ke indlela imichiza synthesis isetyenziselwa synthesis i-polylactic acid kunye nobunzima ethile molekyuli. 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 indalo 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. njl., okwangoku zisetyenziswa ikakhulu kwimpahla yangaphantsi (impahla yangaphantsi, impahla yangaphandle), ishishini (ukwakha, ezolimo, amahlathi, ukwenza iphepha) kunye nezonyango kunye nezempilo.
