Mu ntchito yathu ya tsiku ndi tsiku ndi moyo, bola ngati mumvetsera pang'ono, mudzapeza kuti nthawi zambiri timagwiritsa ntchito kapena kuona matumba a kraft.Mwachitsanzo, pogula chakudya, matumba a mapepala a kraft amagwiritsidwa ntchito poyikapo.Chochititsa chidwi kwambiri pa iwo ndikuti ali olimba mtima komanso osamata.Mafuta, ndiye mawonekedwe a mapepala a bulauni ndi ati?Tiyeni tikupezereni pansipa!

Zida zazikulu za matumba a mapepala zimaphatikizapo mapepala anayi apadera: khadi loyera, chikopa cha kraft, khadi lakuda ndi pepala lamkuwa.Monga momwe dzinalo likusonyezera, matumba a kraft amapangidwa ndi pepala la kraft.Ili ndi kulimba kwambiri komanso kulimba kwake ndipo sikophweka kung'ambika., mapepala a kraft ndi abwino kwambiri kusindikiza mapepala amtundu umodzi kapena awiri omwe sakhala okongola kwambiri.Kulemera kwa pepala la kraft lomwe amagwiritsidwa ntchito kwambiri ndi pafupifupi magalamu 157 mpaka 300 magalamu.

Pogwiritsira ntchito, matumba a mapepala a kraft amatha kugawidwa kukhala kusindikiza kutentha, kusindikiza mapepala ndi kuyika pansi molingana ndi njira zotsegula ndi kumbuyo.Kuchuluka kwa ntchito kumaphatikizapo mafakitale ambiri, monga: zida za mankhwala, chakudya, zowonjezera mankhwala, zomangira, kugula m'masitolo akuluakulu, zovala, ndi zina zotero.Mitunduyo imagawidwa kukhala pepala loyera la kraft ndi pepala lachikasu la kraft.Wosanjikiza wa zinthu PP angagwiritsidwe ntchito kuvala pepala kupereka madzi.Mphamvu ya thumba ikhoza kupangidwa kukhala imodzi kapena isanu ndi umodzi malingana ndi zofuna za kasitomala.Kusindikiza ndi kupanga matumba kumaphatikizidwa.

Matumba amapepala a Kraft amatha kugawidwa mwatsatanetsatane makamaka kuchokera kuzinthu zitatu: zakuthupi, mtundu wa thumba ndi maonekedwe, motere:

01.Malinga ndi zinthu

Malinga ndi zomwe zili, matumba a pepala a kraft amatha kugawidwa kukhala: ① matumba a pepala a kraft, ② mapepala a aluminiyamu ophatikizika a mapepala a kraft (kraft pepala lopangidwa ndi aluminiyamu zojambulazo), ③ matumba opangidwa ndi mapepala opangidwa ndi kraft (nthawi zambiri matumba akuluakulu).
