Polylactic acid (PLA) ndi polima yopangidwa ndi lactic acid ngati chinthu chachikulu chopangira zinthu, chomwe chimachokera kwathunthu ndipo chimatha kubwezeretsedwanso. Njira yopangira polylactic acid ndi yopanda kuipitsa, ndipo chinthucho chimatha kuwonongeka kuti chiziyenda bwino m'chilengedwe, kotero ndi chinthu chabwino kwambiri cha polima wobiriwira. Polylactic acid (PLA)) ndi mtundu watsopano wa zinthu zowola zazinthu zapulasitiki, Kusindikiza kwa 3DWowuma wotengedwa kuchokera ku zomera zongowonjezedwanso (monga chimanga) amapangidwa kukhala lactic acid mwa kuwiritsa kenako n’kusinthidwa kukhala polylactic acid mwa kupangidwa kwa polima.

Poly (lactic acid) ili ndi kuthekera kowononga bwino chilengedwe ndipo imatha kuwonongeka kwathunthu ndi 100% ya tizilombo toyambitsa matenda m'nthaka mkati mwa chaka chimodzi itatha kutayidwa, zomwe zimapangitsa kuti carbon dioxide ndi madzi zisawonongeke komanso kuti chilengedwe chisaipitsidwe. Malinga ndi malipoti a nkhani, mpweya wa carbon dioxide padziko lonse lapansi udzakwera kufika pa 60 ℃ mu 2030. Mapulasitiki wamba akadali kutenthedwa, zomwe zimapangitsa kuti mpweya wambiri wowonjezera kutentha utulutsidwe mumlengalenga, pomwe polylactic acid imakwiriridwa m'nthaka kuti iwonongeke. Mpweya woipa womwe umabwera umapita mwachindunji kuzinthu zachilengedwe za nthaka kapena umatengedwa ndi zomera, sudzatulutsidwa mumlengalenga, sudzayambitsa Greenhouse Effect.

Poly (lactic acid) ndi yoyenera njira zosiyanasiyana zopangira zinthu monga kupanga ma blow molding ndijekeseni yopangira jekeseni. Ndi yosavuta kuikonza komanso imagwiritsidwa ntchito kwambiri. Itha kugwiritsidwa ntchito pokonza mitundu yonse ya ziwiya za chakudya, chakudya chopakidwa m'matumba, mabokosi a chakudya chachangu, nsalu zosalukidwa, nsalu zamafakitale ndi zachikhalidwe kuyambira zogwiritsidwa ntchito m'mafakitale mpaka zogwiritsidwa ntchito m'mafakitale. Kenako imakonzedwa kukhala nsalu zaulimi, nsalu zachipatala, nsanza, zinthu zaukhondo, nsalu zotsutsana ndi ultraviolet zakunja, nsalu ya hema, matiresi apansi ndi zina zotero, msika umakhala wabwino kwambiri. Zikuoneka kuti mphamvu zake zamakanika ndi zakuthupi ndi zabwino.

Makhalidwe oyambira a polylactic acid (PLA) ndi mapulasitiki opangidwa ndi petrochemical ndi ofanana, kutanthauza kuti, angagwiritsidwe ntchito kwambiri popanga zinthu zosiyanasiyana. Polylactic acid ilinso ndi kuwala kwabwino komanso mawonekedwe abwino, zomwe zimafanana ndi filimu yopangidwa kuchokera ku polystyrene ndipo sizingaperekedwe ndi zinthu zina zomwe zimatha kuwonongeka.
