Zopangira zazikulu za kapu yamapepala ndi pepala, pomwe pepala loyambirira ndi mtengo ndi nsungwi.Anthu ambiri sangalephere kunena kuti ngati kukula kwakukulu kwa kupanga chikho cha mapepala kudzachititsa kuti mitengo iwonongeke kwambiri, ndipo idzawononga zinthu zomwe zikugwirizana nazo, zidzawononganso chilengedwe kwambiri. .Lingaliro lamtunduwu ndilomveka, lingakhale lopanda kulingalira za zochitika zina za kuwonongeka kwachisawawa kwa nkhalango, kusiya malingaliro oipa ambiri, komabe, kudula mitengo kwamasiku ano kwaletsedwa bwino pansi pa ndondomeko ndi malamulo okhwima a boma.Pakali pano, zipangizo zonse zamatabwa zomwe timagwiritsa ntchito ndi nkhalango zokonzedwanso zomwe zingathe kudulidwa, chitsanzo chothandizira ndi mtengo wachuma womwe ungagwiritsidwe ntchito moyenera.Chifukwa chake, makampani opanga chikho cha mapepala adzangoyendetsa chitukuko cha mafakitale okhudzana nawo, bola ngati kuwongolera koyenera, sipadzakhala chodabwitsa cha kuwonongeka kwachilengedwe kwachilengedwe komwe anthu akuda nkhawa nako.Makapu a Mapepala adatsogolera makampani opanga chitukuko choyamba ndi makampani opanga mapepala, chifukwa chinthu chachikulu cha makapu a mapepala ndi mapepala.Ngakhale kugwiritsiridwa ntchito kwa mitengo panopa pokonzekera, koma kupititsa patsogolo kugwiritsidwa ntchito kwakukulu kwa nkhuni pakupanga mapepala ndi kupeza njira zina zopangira mapepala ndi nkhani ya kufufuza kosalekeza.Anthu chidwi chilengedwe chilengedwe, komanso kulimbikitsa anthu pepala mipando yobwezeretsanso kafukufuku.
Zopangira zina za kapu ya pepala ndi pepala lokhala ndi zoweta, lopangidwa ndi PLA lopangidwa ndi kunja, pepala lopangidwa ndi PE lochokera kunja.PE ❖ kuyanika ndi ❖ kuyanika makina (laminating makina) pa pepala ndi wosanjikiza PE (polyethylene) filimu Polylactic asidi CHIKWANGWANI ndi kwathunthu biodegradable kupanga CHIKWANGWANI amene angapezeke ku mbewu.Zinyalalazo zimatha kuwola kukhala carbon dioxide ndi madzi ndi tizilombo toyambitsa matenda m'nthaka kapena m'madzi a m'nyanja.Ikatenthedwa, sichidzatulutsa mpweya wapoizoni ndikuyambitsa kuipitsa kwina.Pali gulu limodzi la hydroxyl ndi gulu limodzi la carboxyl mu molekyulu imodzi ya lactic acid, mamolekyu ambiri a lactic acid palimodzi, -OH ndi mamolekyu ena-COOH dehydration condensation, -COOH ndi mamolekyu ena-OH dehydration condensation, polima omwe amapanga amatchedwa polylactic acid.Polylactic acid, yomwe imadziwikanso kuti polylactide, ndi ya banja la polyester.Polylactic acid (PLA) ndi mtundu wa zinthu za polima zomwe zitha kupezedwa ndi polymerization ya lactic acid.Poganizira zofunikira zapadera za chitetezo cha chilengedwe komanso ukhondo wa makapu a mapepala, ziyenera kulimbikitsanso chitukuko cha luso la PLA ndi PE kupita kumalo apamwamba.Ubwino wa chakudya pawokha umafunika chisamaliro, komanso mtundu wa ziwiya zomwe zimagwiritsidwa ntchito pazakudya ndi zakumwa.
