Mtundu uwu wa zamkati umasungabe mtundu wachilengedwe wa zopangira, nthawi zambiri kuyambira wachikasu wotumbululuka mpaka bulauni wakuda, ndipo uli ndi gawo lalikulu la lignin ndi zigawo zina zopanda cellulose. Mtengo wopangira zamkati wamtundu wachilengedwe ndi wochepa kwambiri, ndipo umagwiritsidwa ntchito kwambiri m'minda yomwe safuna pepala loyera kwambiri, monga mapepala odzaza, makatoni, mbali ya pepala la chikhalidwe ndi zina zotero. Ubwino wake ndikusunga mawonekedwe achilengedwe azinthu zopangira, zomwe zimathandizira kugwiritsa ntchito bwino zinthu.

Zamkati zotungidwa zimakhala ndi ukhondo wambiri wa ulusi, katundu wabwino komanso kukhazikika kwamankhwala, ndipo ndiye zida zazikulu zamapepala apamwamba azikhalidwe, mapepala apadera ndi mapepala apanyumba. Chifukwa cha kuyera kwake kwakukulu komanso magwiridwe antchito abwino kwambiri, zamkati zowulitsidwa zimakhala ndi gawo lofunikira pamakampani opanga mapepala.

4. Mapepala oyengedwa Zamkati

Refined Pulp nthawi zambiri amatanthauza zamkati zomwe zimapezedwa pamaziko a zamkati zowulitsidwa, zomwe zimathandizidwanso ndi njira zakuthupi kapena zamankhwala kuti zithandizire kuyeretsa komanso ulusi wa zamkati. Njirayi, yomwe ingaphatikizepo masitepe monga kugaya bwino, kuyesa ndi kuchapa, yapangidwa kuti ichotse ulusi wabwino, zonyansa ndi mankhwala osakwanira bwino kuchokera pazamkati ndikupanga ulusiwo kuti ukhale wobalalika komanso wofewa, potero kumapangitsa kusalala, gloss ndi mphamvu ya pepala.
