Posachedwapa,PLA(polylactic acid) biodegradable tableware zadzetsa kuchulukirachulukira m'makampani ogulitsa zakudya, m'malo mwa zida zamapulasitiki zachikhalidwe, chifukwa cha zabwino zake monga kukhala wobiriwira, wokonda zachilengedwe, wotetezeka, komanso wopanda poizoni. Yakhala galimoto yofunikira polimbikitsa kukhazikitsidwa kwa "dongosolo loletsa pulasitiki" ndikuchita chitukuko chochepa cha carbon.

Pulogalamu ya PLAamagwiritsa ntchito zowuma zongowonjezwq kuzmera monga chimanga ndi mbatata monga zopangira, kuthetsa kudalira mafuta komwe kumachokera ndikukwaniritsa zobwezeretsanso. Ubwino wake waukulu wagonakuwonongeka kwachilengedwe; pansi pa kompositi, imatha kuwonongeka kwathunthu kukhala mpweya woipa ndi madzi mkati mwa miyezi 6-12, kupeŵa "kuipitsa koyera" komwe kumachitika chifukwa cha mapulasitiki achikhalidwe ndikuchepetsanso kupanikizika kwa nthaka ndi zamoyo zam'madzi.

Pankhani ya chitetezo, PLA tableware yadutsa chiphaso chachitetezo cha chakudya. Kupanga sikufuna kuwonjezera mankhwala owopsa monga plasticizers ndi stabilizers. Simatulutsa zinthu zapoizoni monga bisphenol A ikagwiritsidwa ntchito kutentha kwambiri, kuonetsetsa kuti ogula ali ndi thanzi labwino kuchokera pomwe amakumana ndi chakudya, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito pafupipafupi kwambiri monga.Chotsanindizakudya zachangu. Pakadali pano, PLA tableware wakwanitsa zopambana kutentha kukana ndimphamvu yonyamula katundu, kupirira kutentha kuyambira -10 ℃ mpaka 100 ℃. Kulimba kwake komanso kulimba kwake kumafanana ndi zida zamapulasitiki zachikhalidwe, zomwe zimakwaniritsa zosowa za tsiku ndi tsiku zokonzekera komanso zoyendera. Ndi kukweza kwaukadaulo wopanga, mtengo wake watsika pang'onopang'ono, ndipo tsopano umagwiritsidwa ntchito kwambiri m'malesitilanti amkaka, mashopu a tiyi wamkaka, ma canteens, ndi masitolo akuluakulu.

Ogwira ntchito m'mafakitale amati kukwezedwa ndi kugwiritsa ntchito kwa PLA tableware sikungogwirizana ndikuteteza chilengedwendondomeko komanso zimathandiza ogula 'kufunafuna moyo wathanzi. Kuyendetsedwa ndi chithandizo cha ndondomeko ndiluso laukadaulo, idzakhala chisankho chodziwika bwino m'makampani opangira zakudya, zomwe zimapangitsa kuti pakhale chitukuko chobiriwira.
