PLA, kapena polylactic acid, ndi zinthu zomwe zimatha kuwonongeka kuchokera ku zomera, makamaka chimanga. Yakhala ikudziwika kwambiri m'mafakitale osiyanasiyana, makamaka m'magawo onyamula ndi kulemba zilembo. Ichi ndi chifukwa cha kuphatikiza kwake kwapadera kwa ubwino wokhazikika ndi chilengedwe. Ntchito imodzi yotereyi ili mu mawonekedwe a pepala la PLA.
Chithunzi cha PLAndi pepala lopangidwa kuchokera ku filimu ya PLA. Nthawi zambiri amagwiritsidwa ntchito ngati njira yokhazikika yofananira ndi pepala lakale la pulasitiki. Pepalalo ndi lofewa, losinthika, komanso losagwetsa misozi, zomwe zimapangitsa kukhala chisankho chabwino kwambiri cholembera zolemba.
Chimodzi mwazabwino zazikulu za pepala lolemba la PLA ndikuwonongeka kwake. Mosiyana ndi mapepala apulasitiki achikhalidwe, omwe amatenga zaka zingapo kuti awole, pepala la PLA limasweka mwachangu mulu wa kompositi, kuchepetsa kuchuluka kwa zinyalala m'malo otayirako. Izi zimapangitsa kuti ikhale yochezeka komanso yokhazikika pakuzindikiritsa zinthu.
Thezolemba pepala ndi yosavuta kusindikiza. Imavomereza njira zambiri zosindikizira, kuphatikizapo kusindikiza kwa offset, flexography, ndi kusindikiza pazithunzi. Maonekedwe osalala a pepalalo amaonetsetsa kuti zithunzi zosindikizidwa zikhalebe zakuthwa komanso zomveka bwino.
Kuphatikiza apo, pepala lolemba la PLA limapereka kumva bwino kwa wogwiritsa ntchito. Nthawi zambiri amagwiritsidwa ntchito popanga zakudya chifukwa chosakhala ndi poizoni komanso chitetezo chazakudya. Maonekedwe ofewa a pepala komanso kugwirika kwake kumapangitsa kukhala chisankho chabwino kwambiri cholembera zinthu za ogula.
Kufunika kwa pepala la zilembo za PLA kukuyembekezeka kukula m'zaka zikubwerazi pomwe ogula akudziwa zambiri zazachilengedwe komanso kufunikira kwa mayankho okhazikika. Pepala la zilembo za PLA limapereka mgwirizano wabwino pakati pa magwiridwe antchito ndi kuyanjana ndi chilengedwe, ndikupangitsa kuti ikhale chisankho chabwino kwambiri pakuzindikiritsa zinthu.
Pomaliza,Thepepala labelpa PLAndi njira yokhazikika komanso yosamalira zachilengedwe pakuzindikiritsa zinthu. Kuwonongeka kwake, kusindikizidwa, komanso zinthu zopanda poizoni kumapangitsa kuti ikhale chisankho chabwino kwambiri cholembera zinthu zomwe ogula amanyamula komanso kulongedza zakudya. Pomwe kufunikira kwamayankho okhazikika akuchulukirachulukira, pepala lolemba la PLA likuyembekezeka kutenga gawo lofunikira pakukwaniritsa izi.
