O le Polylactic acid (PLA) o se ituaiga fou o meaola fa'avae ma fa'afouina mea e mafai ona fa'aleagaina, lea e faia mai i mea fa'ato'aga o lo'o fa'atūina mai e ala'oa fa'afouina (e pei o sana, manioka, ma isi). E fa'asalaina mea mata masoa ina ia maua ai le kulukose, ona fa'afefeteina lea mai le kulukose ma nisi o galu e maua ai le lactic acid maualuga-mama, ona fa'aaogaina lea o le fa'aogaina o vaila'au e fa'apipi'i ai le polylactic acid ma se mamafa mole. E lelei le biodegradability, ma e mafai ona faʻaleagaina atoa e microorganisms i le natura i lalo o tulaga faʻapitoa pe a uma ona faʻaaogaina, e iu lava ina gaosia le carbon dioxide ma le vai, e aunoa ma le faʻaleagaina o le siosiomaga, lea e aoga tele mo le puipuia o le siosiomaga ma ua aloaia o se mea faʻafefe siosiomaga.
O le polylactic acid e lelei le faʻamautuina o le vevela, o le vevela o le gaosiga o le 170 ~ 230 ℃, ma e lelei le faʻafefeteina. E mafai ona faʻagasolo i auala eseese, e pei o le extrusion, vili, biaxial stretching, ma tui tui. I le faaopoopo atu i le biodegradable, o oloa e faia i le polylactic acid e lelei le biocompatibility, susulu, manino, lagona lima ma le vevela, faʻapea foʻi ma nisi siama faʻamaʻi, mumu mumu ma le UV tetee, o lea e aoga tele. Faʻaaogaina lautele e pei o mea faʻapipiʻi, fiber ma nonwovens, ma isi, o loʻo faʻaaogaina i le taimi nei i lavalava (ofu i totonu, ofu i fafo), alamanuia (fausiaina, faʻatoʻaga, vaomatua, faipepa) ma falemaʻi ma soifua maloloina.
