Kupanga ndi kugwiritsa ntchito makapu a mapepala kumagwirizana ndi ndondomeko ya dziko loteteza chilengedwe.Kusintha makapu apulasitiki otayika kumachepetsa "kuipitsa koyera".Kusavuta, ukhondo komanso mtengo wotsika wa makapu amapepala ndiye chinsinsi chosinthira ziwiya zina kuti zizikhala pamsika.Makapu a mapepala amagawidwa m'makapu akumwa ozizira ndi makapu akumwa otentha molingana ndi ntchito zawo.Kuphatikiza pa kukwaniritsa zosowa za kulongedza ndi kukonza ntchito, zinthu za makapu a mapepala ziyeneranso kukwaniritsa kusinthasintha kwawo kusindikiza.Pakati pa zinthu zambiri zamakono zosindikizira, zofunikira zosindikizira kutentha kwa makapu a mapepala ziyeneranso kukumana.
Chikho cha pepala chomwe chimapangidwa ndi makina a chikho cha pepala chimapangidwa ndi kusindikiza kwachindunji kwa pepala lachikho cha pepala, kudula kufa, kupanga kukonza, ndi kupopera mbewu phula lazakudya pamwamba.Njira yopangira kapu yakumwa yotentha ndikuti pepala loyambira lachikho la pepala limakutidwa mu pepala la makapu, losindikizidwa, lodulidwa-kufa, ndi kukonzedwa.Mapepala apansi a makapu amapepala amapangidwa ndi ulusi wa zomera.Kapangidwe kake kamakhala kogwiritsa ntchito ulusi wazomera monga matabwa a coniferous ndi matabwa olimba kuti adutse pagulu lazamkati pambuyo pa pulping.Chikho cha pepala cha makina opangira makapu amapangidwa ndi pepala la makapu a pepala ndi tinthu tating'onoting'ono ta pulasitiki totulutsa ndikuphatikizidwa.Utomoni wa pulasitiki nthawi zambiri umagwiritsa ntchito polyethylene resin (PE).Pepala loyambira la kapu yamapepala limakutidwa ndi filimu ya PE ya mbali imodzi kapena filimu ya PE yokhala ndi mbali ziwiri kuti ikhale pepala limodzi la kapu ya PE kapena makapu awiri a PE.
Pepala lokutidwa ndi PE lili ndi yakeyake yopanda poizoni, yopanda fungo, yopanda kukoma;ntchito zaukhondo ndizodalirika;mankhwala katundu ndi okhazikika;thupi ndi makina katundu ali moyenera, zabwino ozizira kukana;kukana madzi, kukana chinyezi ndi kukana kwa oxygen ndi mafuta;zinthu zabwino kwambiri zomangira komanso ntchito yabwino yosindikiza kutentha.PE ili ndi voliyumu yayikulu yopanga, gwero losavuta komanso mtengo wotsika, koma siyoyenera kuphika kutentha kwambiri.Ngati kapu ya pepala ili ndi zofunikira zapadera, utomoni wa pulasitiki wokhala ndi ntchito yofananira uyenera kugwiritsidwa ntchito popangira laminating
