Polylactic acid (PLA) ndi polima wopangidwa ndi lactic acid monga chopangira chachikulu, chomwe chimakhala chokwanira ndipo chimatha kupangidwanso.Kapangidwe ka asidi a polylactic sikumayipitsidwa, ndipo mankhwalawa amatha kusinthidwa kuti akwaniritse kufalikira kwachilengedwe, chifukwa chake ndi chinthu chabwino chobiriwira cha polima.Polylactic acid (PLA)) ndi mtundu watsopano wa zinthu zomwe zimatha kuwonongekazinthu zapulasitiki, 3D kusindikiza.Wowuma wotengedwa ku zomera zongowonjezwdwa (monga chimanga) amapangidwa kukhala lactic acid ndi nayonso mphamvu ndiyeno n'kukhala asidi polylactic ndi polima kaphatikizidwe.

Poly (lactic acid) ili ndi biodegradability yabwino kwambiri ndipo imatha kuonongeka ndi 100% ya tizilombo tating'onoting'ono m'nthaka pasanathe chaka chimodzi atasiyidwa, zomwe zimapangitsa kuti mpweya woipa ndi madzi usawononge chilengedwe.Kupindula kwenikweni "kuchokera ku chilengedwe, kukhala m'chilengedwe".Kutulutsa mpweya wa carbon dioxide padziko lonse malinga ndi malipoti a nkhani, kutentha kwapadziko lonse kudzakwera kufika pa 60 ℃ mu 2030. Mapulasitiki wamba akadali otenthedwa, zomwe zimapangitsa kuti mpweya wambiri wowonjezera kutentha utuluke mumlengalenga, pamene asidi a polylactic amakwiriridwa m'nthaka kuti awonongeke. .The chifukwa mpweya woipa amapita mwachindunji mu nthaka organic kanthu kapena otengedwa ndi zomera, si kukhetsedwa mu mlengalenga, sizidzachititsa wowonjezera kutentha Mmene.

Poly (lactic acid) ndi oyenera njira zosiyanasiyana processing monga kuwomba akamaumba ndijekeseni akamaumba.Ndi yosavuta pokonza ndi ambiri ntchito.Itha kugwiritsidwa ntchito pokonza zotengera zamitundu yonse, zakudya zophatikizika, mabokosi a chakudya chamasana mwachangu, nsalu zosalukidwa, nsalu zamakampani ndi zaboma kuchokera ku mafakitale kupita ku boma.Kenako amasinthidwa kukhala nsalu zaulimi, nsalu zachipatala, nsanza, zinthu zaukhondo, nsalu zakunja zotsutsana ndi ultraviolet, nsalu za hema, matiresi apansi ndi zina zotero, chiyembekezo chamsika chimalonjeza kwambiri.Zitha kuwoneka kuti makina ake ndi mawonekedwe ake ndi abwino.

Zofunikira zakuthupi za polylactic acid (PLA) ndi mapulasitiki a petrochemical synthetic ndi ofanana, ndiye kuti, amatha kugwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana.Polylactic acid imakhalanso ndi glossiness yabwino komanso yowonekera, yomwe ili yofanana ndi filimu yopangidwa kuchokera ku polystyrene ndipo sangaperekedwe ndi zinthu zina zowonongeka.
