I-Polylactic acid(PLA) iyinto entsha ebolayo esebenzisa isitashi izinto ezingavuthiwe ezikhishwa ezinsizeni zezitshalo ezivuselelekayo (njengommbila).Isitashi sezinto eziluhlaza siyagcotshwa ukuze sithole i-glucose, sivutshelwa yi-glucose nezinhlobo ezithile ukuze kukhiqizwe i-lactic acid ngokuhlanzeka okuphezulu, bese inani elithile le-PLA lihlanganiswa ngendlela yokuhlanganisa amakhemikhali.Ine-biodegradability enhle, futhi ngemva kokusetshenziswa okungacekelwa phansi ngokuphelele amagciwane emvelweni, ekugcineni ikhiqize isikhutha namanzi, okungangcolisi imvelo futhi kuzuzisa kakhulu ekuvikelweni kwemvelo.Ngakho njengoba sazi sonke, i-PLA ibonwa njengemvelo. izinto ezinobungane.
Ngokugqugquzelwa komhlaba wonke kokuvinjelwa kwepulasitiki, i-PLA iya ngokuya isetshenziswa ezinhlotsheni ezahlukahlukene zemikhiqizo yepulasitiki, njengezikhwama zokupakisha, amabhokisi okudla alahlwayo nezikhwama ezingalukiwe.
Ama-nonwovens e-PLA angaba ngu-100% ukuwohloka endaweni yemvelo, nokusebenza kahle, hhayi kuphela okulungele ukuthunga okwenziwa, kodwa futhi afanelekele umshini wokwenza isikhwama se-welding welding we-ultrasonic, kodwa ngenxa yomthamo ulinganiselwe, ngakho intengo iphakeme kune I-PP engeyona eyelukiweyo , ngakho-ke ukwamukelwa kwemakethe akuphakeme, kodwa kholelwa ukuthi ngokuthuthukiswa kobuchwepheshe bokukhiqiza be-PLA kanye nokwandiswa kwesikali sokukhiqiza, i-PLA izoba yimpahla eyinhloko yemikhiqizo yokupakisha.
