I-Polylactic acid (PLA) luhlobo olutsha lwezinto ezibolayo ezisekelwe kwibhayoloji nezivuselelekayo, ezenziwe ngezinto eziluhlaza zesitatshi ezicetywayo zizityalo ezivuselelekayo (ezifana nombona, i-cassava, njl.njl.). Izinto eziluhlaza zesitatshi ziyasuswa ukuze kufunyanwe i-glucose, emva koko zivundiswe kwi-glucose nakwiintlobo ezithile ukuvelisa i-lactic acid ecocekileyo kakhulu, emva koko indlela yokwenziwa kweekhemikhali isetyenziselwa ukwenza i-polylactic acid enobunzima obuthile be-molecular. Inokubola kakuhle, kwaye inokonakala ngokupheleleyo ziintsholongwane kwindalo phantsi kweemeko ezithile emva kokusetyenziswa, ekugqibeleni ivelise i-carbon dioxide namanzi, ngaphandle kokungcolisa okusingqongileyo, okuluncedo kakhulu ekukhuseleni okusingqongileyo kwaye kuqatshelwa njengezinto ezinobuhlobo nokusingqongileyo.
I-asidi ye-polylactic inozinzo oluhle lobushushu, ubushushu bokucubungula yi-170 ~ 230℃, kwaye inokumelana okuhle kwe-solvent. Ingacutshungulwa ngeendlela ezahlukeneyo, ezinje ngokuphuma, ukujikelezisa, ukolula kabini, kunye nokubumba i-injection blow. Ukongeza ekubeni inokubola, iimveliso ezenziwe nge-asidi ye-polylactic zinokuhambelana kakuhle kwe-bio, ukuqaqamba, ukucaca, ukuva ngesandla kunye nokumelana nobushushu, kunye nokumelana neebhaktheriya ezithile, ukulibaziseka komlilo kunye nokumelana ne-UV, ngoko ke ziluncedo kakhulu. Zisetyenziswa kakhulu njengezinto zokupakisha, iifayibha kunye nezinto ezingalukwanga, njl.njl., okwangoku zisetyenziswa kakhulu kwiimpahla (impahla yangaphantsi, impahla yangaphandle), kushishino (ukwakha, ezolimo, amahlathi, ukwenza amaphepha) kunye namacandelo ezonyango kunye nezempilo.
