Aside Polylactic (PLA) ni ubwoko bushya bw'ibikoresho bibora bishingiye ku binyabuzima kandi bishobora kuvugururwa, bikorwa mu bikoresho fatizo bya starch byatanzwe n'ibimera bishobora kuvugururwa (nk'ibigori, imyumbati, nibindi). Ibikoresho fatizo bya starch bivangwa kugira ngo haboneke glucose, hanyuma bigatunganywa muri glucose n'ubwoko bumwe na bumwe kugira ngo hakorwe aside lactic nziza cyane, hanyuma hagakoreshwa uburyo bwo gukora imiti mu gukora aside polylactic ifite uburemere runaka bwa molekile. Ifite ubushobozi bwo kuvugururwa neza, kandi ishobora kwangirika burundu na mikorobe mu miterere runaka nyuma yo kuyikoresha, amaherezo ikabyara dioxyde de carbone na amazi, idahumanya ibidukikije, ibyo bikaba ingirakamaro cyane mu kurinda ibidukikije kandi bizwi nk'ibikoresho birengera ibidukikije.
Aside polylactic ifite ubushyuhe bwiza, ubushyuhe bwo kuyitunganya ni 170 ~ 230°C, kandi ifite uburinzi bwiza bwo kuyitunganya. Ishobora gutunganywa mu buryo butandukanye, nko gusohora, kuzunguruka, kunanura ibice bibiri, no gusya inshinge. Uretse kuba ishobora kubora, ibicuruzwa bikozwe muri aside polylactic bifite ubushobozi bwo guhuza neza n'ibintu, gukayangana, kubonerana, gukora ku ntoki no kurwanya ubushyuhe, ndetse no kurwanya bagiteri zimwe na zimwe, kudakoresha umuriro no kurwanya imirasire ya UV, bityo ni ingirakamaro cyane. Ikoreshwa cyane nk'ibikoresho byo gupfunyika, insinga n'ibindi, ubu ikoreshwa cyane mu myenda (imyenda y'imbere, imyenda yo hanze), inganda (ubwubatsi, ubuhinzi, amashyamba, gukora impapuro) no mu buvuzi n'ubuzima.
