Mapanelo a mbali ziwiri amapangidwa motengera kukula kwake komanso kukula kwake.Kapangidwe kake kameneka kagawika kamene kamakhala pansi, chigawo chapakati, chigawo chapakati, chapamwamba komanso chophimba.Pansi pa pepala loyera ndi imvi mu mtundu.Zimapangidwa ndi deinking ya zinyalala nyuzipepala, kotero zosakaniza za wosanjikiza pansi kwambiri osakaniza;pamwamba ndi yoyera, yopyapyala yopaka pamwamba yosakanikirana ndi zinthu zopangira mankhwala monga ufa wa kaolin, zomangira, ndi zina zotero. Zosanjikiza pamwamba (zokutidwa pamwamba) zimakhala zoyera kwambiri, kuyamwa kwa inki bwino, flatness yabwino, gloss yabwino yosindikizira, kuuma kwabwino ndi kupindika bwino. kukana kwa makatoni palokha.Pambuyo pa pepala lokhala ndi mbali ziwiri zakhala zophimbidwa, zowonongeka zakhala zikuyenda bwino kwambiri.Ikhoza kukwaniritsa zofunikira za kusindikiza kwamtundu wapamwamba, ndipo ingagwiritsidwe ntchito ngati zinthu zamtengo wapatali zamabokosi opangira zinthu zapakati komanso zapamwamba.

Foling boxboard ndi yokhuthala, yamphamvu, yoyera makatoni.Amapangidwa kuchokera ku 100% bleached kraft wood zamkati omwe amamenya kwaulere.Amapangidwa powonjezera zodzaza zoyera monga talcum ufa ndi barium sulfate pamakina a pepala a Fourdrinier, kenako kuwerengera kapena kusindikiza.

Pali kusiyana koonekeratu pakati pa mbali ziwiri ndi FBB pamayamwidwe amadzi ndi roughness.FBB imakhala ndi mayamwidwe apamwamba komanso otsika kwambiri.Kuchuluka kwa absorbency kungapangitse kuti madontho apindule mosavuta, pamene kutsika kwapang'onopang'ono kumapangitsa kuti pepala likhale lochepa kwambiri chifukwa cha kusindikiza ndi filimu yochepetsetsa ya inki, yomwe imathandizira kuchepetsa madontho.Chifukwa chake, bolodi lokhala ndi mbali ziwiri silili bwino ngati FBB pankhani yotulutsa mawu.

Kusalala kwa mapepala, gloss ndi kuyamwa kwamadzi ndizofunikiranso.FBB ili ndi mapeto apamwamba kwambiri.Inkiyo ikasindikizidwa pamapepala, capillary mu zokutira imatenga mofanana, zomwe zimatsimikizira kusinthasintha kwakukulu ngakhale ndi inki yaying'ono.Ndizokhazikika ndipo zimatha kupanga filimu yofananira komanso youma ya inki.Zojambulazo ndi zonyezimira, zokongola komanso zosanjikiza.Pepalali limakhala losalala kwambiri, lowoneka bwino komanso lonyezimira bwino.Kuwala kukadutsa munsanjika ya inki ndikugunda pepala, kuwala kochulukirapo kumalowetsanso inkiyo mwa mawonekedwe owoneka bwino ndikulowa m'gawo la owonera.Diso.Ndi mbali iyi yokha ya kuwala yomwe ingawonetsere mtundu wa inki.Kumbali ina, porosity ya pamwamba ya bolodi yamagulu awiri ndi yaikulu, pamwamba pake ndi yosagwirizana, kuchuluka kwa inki ndi kakang'ono, pepala silingathe kukhudzana ndi inki yosindikizira, ndipo chiwerengero chotengera ndi chochepa;pamene inki ili yaikulu, kutengerako kumakhala kwakukulu kwambiri, kuyamwa kumakhala kochuluka kwambiri, ndipo inki yambiri Binder imatengedwa ndi pepala, tinthu tating'onoting'ono ta pigment sizitetezedwa mokwanira, inkiyo siigwiritsidwa ntchito mwamsanga, ndipo kupaka utoto ndikosavuta.
