Matumba a mapepala ndi gulu lalikulu. Amakhala ndi mitundu yosiyanasiyana ya zinthu, pomwe thumba lililonse lomwe lili ndi gawo la pepala popangidwa limatha kutchedwa thumba la pepala. Pali mitundu yosiyanasiyana ya matumba a mapepala, zipangizo, ndi masitaelo.
Kutengera ndi zinthu zomwe zili mkati mwake, zitha kugawidwa m'magulu awa: matumba a pepala oyera a makatoni, matumba a pepala oyera, matumba a pepala la mkuwa, matumba a pepala la kraft, ndi ena opangidwa kuchokera ku mapepala apadera.
Kadibodi Yoyera: Yolimba komanso yokhuthala, yokhala ndi kulimba kwambiri, mphamvu yophulika, komanso yosalala, kadibodi yoyera imapereka malo osalala. Makulidwe omwe amagwiritsidwa ntchito nthawi zambiri amakhala kuyambira 210-300gsm, ndipo 230gsm ndiye otchuka kwambiri. Matumba a mapepala osindikizidwa pa kadibodi yoyera ali ndi mitundu yowala komanso kapangidwe kabwino ka pepala, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri chosinthira.
Pepala la Copperplate:
Pokhala ndi malo osalala komanso oyera, oyera kwambiri, osalala, komanso owala, pepala la copperplate limapereka zithunzi ndi zithunzi zosindikizidwa kukhala ndi mawonekedwe atatu. Limapezeka mu makulidwe kuyambira 128-300gsm, limapanga mitundu yowala komanso yowala ngati khadi loyera koma lolimba pang'ono.
Pepala Loyera Lopangidwa ndi Kraft:
Ndi mphamvu zambiri, kulimba, komanso mphamvu, pepala loyera la kraft limapereka makulidwe okhazikika komanso mtundu wofanana. Mogwirizana ndi malamulo oletsa kugwiritsa ntchito matumba apulasitiki m'masitolo akuluakulu komanso zomwe zikuchitika padziko lonse lapansi, makamaka ku Europe ndi America, pankhani ya matumba apepala osawononga chilengedwe kuti achepetse kuipitsidwa kwa pulasitiki, pepala loyera la kraft, lopangidwa ndi matabwa oyera 100%, ndi loteteza chilengedwe, siliwononga chilengedwe, ndipo limatha kubwezeretsedwanso. Limagwiritsidwa ntchito kwambiri komanso nthawi zambiri lopanda utoto pamatumba a zovala oteteza chilengedwe komanso matumba apamwamba ogulitsira. Makulidwe wamba amakhala pakati pa 120-200gsm. Chifukwa cha kukongola kwake kosalala, sikoyenera kusindikizidwa ndi inki yolemera.
Pepala Lopangidwa ndi Kraft (Lakuda Lachilengedwe):
Limadziwikanso kuti pepala lachilengedwe la kraft, lili ndi mphamvu komanso kulimba kwambiri, nthawi zambiri limawoneka ngati mtundu wa bulauni-wachikasu. Ndi kukana kwabwino kwa misozi, mphamvu yophulika, komanso mphamvu yosinthasintha, limagwiritsidwa ntchito kwambiri pogula matumba ndi ma envulopu. Makulidwe ofanana amakhala pakati pa 120-300gsm. Pepala la kraft nthawi zambiri limakhala loyenera kusindikiza mitundu imodzi kapena iwiri kapena mapangidwe okhala ndi mitundu yosavuta. Poyerekeza ndi makatoni oyera, pepala loyera la kraft, ndi pepala la copperplate, pepala lachilengedwe la kraft ndilotsika mtengo kwambiri.
Pepala Loyera Lokhala ndi Imvi: Pepalali lili ndi mbali yoyera, yosalala yakutsogolo ndi kumbuyo kotuwa, komwe kumapezeka nthawi zambiri m'makulidwe a 250-350gsm. Ndi lotsika mtengo pang'ono kuposa khadi loyera.
Kadi Yakuda:
Pepala lapadera lakuda mbali zonse ziwiri, lodziwika ndi kapangidwe kake kosalala, wakuda bwino, kulimba, kupindika bwino, malo osalala komanso athyathyathya, mphamvu yayikulu yogwira, komanso mphamvu yophulika. Likupezeka mu makulidwe kuyambira 120-350gsm, khadi lakuda silingathe kusindikizidwa ndi mitundu ndipo ndi loyenera kupangidwa ndi golide kapena siliva, zomwe zimapangitsa kuti likhale ndi matumba okongola kwambiri.
Kutengera ndi njira zotsekera thumba, pansi, ndi kutsekera, pali mitundu inayi ya matumba a mapepala: matumba otseguka osokedwa pansi, matumba otseguka okhala ndi guluu pakona, matumba osokedwa amtundu wa valve, ndi matumba omata okhala ndi guluu wa flat hexagonal end.
Kutengera ndi mawonekedwe a chogwirira ndi mabowo, amatha kugawidwa m'magulu awa: NKK (mabowo obowoka ndi zingwe), NAK (opanda mabowo ndi zingwe, ogawika m'mitundu yosapindika ndi yokhazikika), DCK (matumba osapindika ndi zingwe okhala ndi zogwirira zodulidwa), ndi BBK (yokhala ndi tongue flap ndi mabowo obowoka).
Kutengera ndi momwe amagwiritsidwira ntchito, matumba a mapepala amaphatikizapo matumba a zovala, matumba a chakudya, matumba ogulira zinthu, matumba amphatso, matumba a mowa, maenvulopu, zikwama zam'manja, matumba a pepala la sera, matumba a mapepala opangidwa ndi laminated, matumba a mapepala okhala ndi mapepala anayi, matumba a mafayilo, ndi matumba a mankhwala. Kugwiritsa ntchito kosiyanasiyana kumafuna kukula ndi makulidwe osiyanasiyana, kotero kusintha ndikofunikira kuti pakhale kugwiritsa ntchito bwino ndalama, kuchepetsa zinthu, kuteteza chilengedwe, komanso kugwiritsa ntchito bwino ndalama zamakampani, kupereka chitsimikizo chochulukirapo.
