Amapangidwa makamaka ndi udzu wachilengedwe ndi mapepala otayira powamenya kuti makatoni oyambirirawo akhale ofanana ndi makatoni achikasu, kenako nkukulungidwa kukhala ngati corrugated kudzera mu makina opangira, kenako n’kulumikizidwa ndi pepala la bokosi ndi guluu monga sodium silicate pamwamba.

Ma corrugations a makatoni opangidwa ndi corrugations ali ngati zitseko zolumikizidwa zolumikizidwa, zomwe zimakonzedwa motsatizana ndipo zimathandizana kuti zipange kapangidwe ka triangular. Zili ndi zotsatira zabwino; zimatha kupangidwa kukhala ma pad kapena zotengera zamitundu yosiyanasiyana malinga ndi zosowa, zomwe zimakhala zosavuta komanso zachangu kuposa zipangizo za pulasitiki; sizimakhudzidwa kwambiri ndi kutentha, zimakhala ndi mawonekedwe abwino a mthunzi, sizimawonongeka ndi kuwala, ndipo nthawi zambiri sizimakhudzidwa kwambiri ndi chinyezi. Komabe, sizoyenera kugwiritsidwa ntchito kwa nthawi yayitali pamalo omwe ali ndi chinyezi chambiri, zomwe zingakhudze mphamvu zake.
