Ndi chitukuko chofulumira cha anthu athu,Makapu a mapepala a PLAakukhala otchuka kwambiri.Tiyi wa khofi ndi mkaka ali ndi msika wabwino, makapu a mapepala otayidwa ndi zivindikiro zathandizira kwambiri.Makasitomala ambiri amakonda kugwiritsa ntchito makapu a mapepala a PLA, chifukwa pepala la PLA ndi lopanda madzi, ndipo limatha kusunga makapu owuma, otetezeka komanso osavulaza.Ubwino wa makapu a mapepala a PLA awonetsedwa pansipa.

1.Makapu a mapepala a PLAkukhala ndi kukana madzi, mpweya wabwino permeability.Chikho ichi chimakhala ndi mphamvu zapamwamba komanso mphamvu za interlaminar, chifukwa kuchuluka kwa malowedwe ndi apamwamba kuposa zipangizo zina.Makapu a pepala a PLA ndi antibacterial, ndipo amatha kuyamwa ammonia.

2. Izieco-friendly paper makapu ogulitsandi pepala chakudya, ndipo ali ndi ubwino mildew umboni, mayamwidwe madzi ndi kukana madzi.Kuzimata filimu amapangidwa mwa njira yapadera ndi mapuloteni monga ❖ kuyanika pa pepala, amene angathe kupirira kutentha, kuteteza kukokoloka, kukhala yabwino pokonza chakudya, ndipo musachite kuipitsa chilengedwe.

3. Polylactic acid (PLA) ndi chinthu chatsopano chochokera ku biodegradable, chomwe chimapangidwa kuchokera ku wowuma wotengedwa kuchokera kuzinthu zongowonjezereka za zomera (monga chimanga, chinangwa, etc.).Wowuma amasanjidwa kuti atenge shuga, yemwe amafufuzidwa kudzera mumtundu wina wa mabakiteriya kuti apange lactic acid yoyera, kenako lactic acid imapangidwa kuti ipeze polylactic acid.PLAkapu ya pepala yotayidwaali ndi biodegradability wabwino ndipo akhoza kuonongeka kotheratu ku mpweya woipa ndi madzi ndi tizilombo tating'onoting'ono m'chilengedwe pansi pamikhalidwe yapadera, zomwe sizimayambitsa kuipitsa chilengedwe.

Makapu a pepala a PLA amagwiritsa ntchito zinthu zachilengedwe zongowonjezwdwanso ngati zopangira, zomwe zimachepetsa kudalira mafuta achikhalidwe komanso zimagwirizana ndi zomwe zimafunikira chitukuko chokhazikika chapadziko lonse lapansi.Ili ndi maubwino onse a ulusi wopangira komanso ulusi wachilengedwe, ndipo imakhala ndikuyenda kwachilengedwe komanso kuwonongeka kwachilengedwe.Poyerekeza ndi ulusi wamba, ulusi wa chimanga uli ndi zinthu zambiri zapadera, zomwe zimapangitsa kuti azikondedwa komanso kuti azikondedwa ndi makasitomala.
