Pepala lopakidwa ndi PE ndi pepala lopakidwa ndi PLA ndi mitundu iwiri yotchuka ya zinthu zophikira chakudya zosawononga chilengedwe. Zipangizo zonsezi zili ndi mawonekedwe ake apadera komanso zabwino zake. M'nkhaniyi, tiyerekeza ziwirizi ndikuwona chomwe chili chabwino.
1. Pepala Lokutidwa ndi PE:
PE imayimira polyethylene, yomwe ndi mtundu wa pulasitiki. Pepala lokutidwa ndi PE ndi pepala lomwe lakutidwa ndi polyethylene woonda. Kuphimba kumeneku kumapangitsa pepalalo kukhala losalowa madzi komanso losagwiritsa ntchito mafuta. Pepala lokutidwa ndi PE limagwiritsidwa ntchito kwambiri mumakampani opanga zakudya, chifukwa ndi njira yotsika mtengo komanso yogwiritsidwa ntchito m'njira zosiyanasiyana.
Ubwino wa Pepala Lokutidwa ndi PE:
Yotsika mtengo: Pepala lopakidwa ndi PE ndi njira yotsika mtengo poyerekeza ndi mitundu ina ya zinthu zopangira chakudya.
Chosalowa madzi: Chophimba cha polyethylene chimapangitsa pepalalo kukhala losalowa madzi, zomwe zimapangitsa kuti likhale labwino kwambiri popangira zakudya zomwe zili ndi zakumwa, monga makapu a mapepala otayidwa.
Yosagwira mafuta: Chophimbacho chimapangitsanso kuti pepalalo lisavutike ndi mafuta, zomwe zimapangitsa kuti likhale labwino kwambiri popakira zakudya zonenepa monga chakudya chofulumira, monga mabaketi a KFC.
Mitundu yosiyanasiyana ya ntchito: Pepala lokutidwa ndi PE lingagwiritsidwe ntchito pa mitundu yonse ya chakudya, kuphatikizapo chakudya chotentha ndi chozizira, chakumwa chozizira, makapu a pepala la zakumwa zotentha, ndi zina zotero.
Zovuta za Pepala Lokutidwa ndi PE:
Siziwola: Chophimba cha polyethylene sichimawola, zomwe zikutanthauza kuti zingatenge nthawi yayitali kuti ziwole.
Sizingatheke kupangidwa manyowa: Pepala lopakidwa ndi PE silingathe kupangidwa manyowa, zomwe zikutanthauza kuti silingagwiritsidwe ntchito ngati chosinthira nthaka.
Zinthu zopangidwa ndi pulasitiki: Pepala lokutidwa ndi PE lili ndi pulasitiki woonda, zomwe zingakhale zovulaza chilengedwe.
2. Pepala Lokutidwa ndi PLA:
PLA imayimira polylactic acid, yomwe ndi mtundu wa bioplastic wopangidwa kuchokera ku zinthu zongowonjezedwanso monga chimanga kapena nzimbe. Pepala lokutidwa ndi PLA ndi pepala lomwe lakutidwa ndi wosanjikiza woonda wa PLA. Kuphimba kumeneku kumapangitsa pepalalo kuti liwonongeke komanso lizitha kupangidwa ndi manyowa, zomwe ndi zabwino kwambiri popangira chakudya chosamalira chilengedwe.
Ubwino wa Pepala Lokutidwa ndi PLA:
Zowola: Chophimba cha PLA chimawola, zomwe zikutanthauza kuti chimatha kuwola kukhala zinthu zachilengedwe.
Chopangidwa ndi manyowa: Pepala lopakidwa ndi PLA likhoza kupangidwa compost, zomwe zikutanthauza kuti lingagwiritsidwe ntchito ngati chosinthira nthaka.
Yogwirizana ndi chilengedwe: Pepala lopakidwa ndi PLA limapangidwa kuchokera ku zinthu zongowonjezedwanso, zomwe zimapangitsa kuti likhale losawononga chilengedwe.
Zotetezeka: Pepala lopakidwa ndi PLA ndi lotetezeka kuti likhudze chakudya, chifukwa lilibe mankhwala owopsa.
Zovuta za Pepala Lokutidwa ndi PLA:
Mtengo wokwera: Poyerekeza ndi zinthu zina zachikhalidwe zophikira chakudya, monga pepala lopakidwa polyethylene, pepala lopakidwa PLA lili ndi mtengo wokwera. Izi zimachitika chifukwa cha zofooka za zipangizo zopangira, njira zopangira, ndi ukadaulo wopanga pepala lopakidwa PLA. Chifukwa cha mtengo wake wokwera, likhoza kukweza mtengo wophikira chakudya.
Kuchuluka kwa ntchito ndi kochepa: Chigawo chachikulu cha pepala lokutidwa ndi PLA ndi bioplastics. Poyerekeza ndi pepala lakale lokutidwa ndi polyethylene, pepala lokutidwa ndi PLA silili bwino ngati pepala lokutidwa ndi polyethylene pankhani yolimbana ndi kutentha, madzi komanso mafuta. Chifukwa chake, kugwiritsa ntchito kwake kuli kochepa.
Kusakhazikika bwino kwa kutentha: Kukhazikika kwa kutentha kwa pepala lokhala ndi PLA sikwabwino ngati kwa pepala lachikhalidwe lokhala ndi polyethylene. Pa kutentha kwambiri, pepala lokhala ndi PLA limasokonekera mosavuta kapena kuwonongeka, zomwe zingakhudze chakudya chomwe chapakidwa.
3. Ndi iti yomwe ili yabwino?
Yankho la funsoli limadalira zosowa za wogwiritsa ntchito. Ngati mtengo wake ndi waukulu, ndiye kuti pepala lokhala ndi PE ndiye njira yabwino kwambiri. Ndi lotsika mtengo komanso lopezeka paliponse, zomwe zimapangitsa kuti likhale lodziwika bwino mumakampani opanga chakudya. Komabe, ngati kusamala zachilengedwe ndikofunikira kwambiri, ndiye kuti pepala lokhala ndi PLA ndiye njira yabwino kwambiri. Lapangidwa kuchokera ku zinthu zongowonjezedwanso, lotha kuwola, komanso lotha kupangidwa ndi manyowa. Ndi lotetezekanso kukhudzana ndi chakudya, zomwe zimapangitsa kuti likhale lodziwika bwino kwa ogula omwe amasamala zachilengedwe.
Pomaliza, mapepala onse okhala ndi PE ndi mapepala okhala ndi PLA ali ndi mawonekedwe ndi ubwino wawo wapadera. Posankha pakati pa awiriwa, ndikofunikira kuganizira zinthu monga mtengo, kusamala chilengedwe, komanso kuyenerera zakudya zinazake. M'zaka khumi zapitazi, kampani yathu yadzipereka pakupanga ndi kupanga Pepala lapamwamba kwambiri lokhala ndi zokutira za PE, kupereka mayankho okonzedwa mwamakonda kwa makasitomala athu kuti akwaniritse zosowa zawo ndi zosowa zawo. Ngati mukufuna kudziwa zambiri za zinthu ndi njira zathu, chonde musazengereze kulankhulana nafe kuti mudziwe zambiri. Tidzakhala okondwa kukuthandizani!
