Pepala lopaka chakudya ndi chinthu cholongedza chokhala ndi zamkati zamatabwa monga zida zazikulu. Iyenera kukwaniritsa zofunikira zotetezedwa ndi madzi, zotetezedwa ndi chinyezi, zosagwira mafuta, komanso zopanda poizoni, ndipo ziyenera kukwaniritsa zofunikira zachitetezo pamapaketi a chakudya. Traditional mafuta umbonipepala lopaka chakudyaNthawi zambiri amagwiritsa ntchito mapepala okutidwa, ndiye kuti, pulasitiki imakutidwa papepala ndi makina oponyera kuti apereke mapepala otsimikizira mafuta.
Komabe, ndi kukhazikitsidwa kwa “Pulasitiki Restriction Order” ya dziko langa ndi kufunikira kowonjezereka kwa chitetezo cha chilengedwe, funde latsopano la “zopaka zobiriwira” zolinga zotetezera chilengedwe zayambika padziko lonse lapansi. “Zovala zobiriwira ” imathandiza kuti chilengedwe chitetezeke ndipo sichivulaza thanzi la munthu. Itha kusinthidwanso ndikugwiritsiridwa ntchito kulimbikitsa chitukuko chokhazikika cha chuma cha dziko. Komabe, pepala lopaka mafuta lopaka mafuta lili ndi zovuta zambiri pamtengo wopangira, kuteteza chilengedwe, komanso kugwiritsa ntchito fiber sekondale.
Mafuta osavomerezekapepala lokulunga chakudya ali ndi mphamvu zowoneka bwino za mafuta. Madontho amafuta amasonkhana pamwamba pa pepala kuti apange mipira, ndipo sangadetse pepalalo ngati ikhala papepala kwa nthawi yayitali. Ndipo kukana kwamadzi kumatha kusinthidwa ndikuwonjezera kuchuluka kwa alkyl ketene dimer. Pepalali limakhala ndi mpweya wabwino, ndipo pomanga chakudya chotentha monga ma hamburger, sichidzakhudza kukoma kwa chakudya chifukwa cha kukulunga kwa nthawi yaitali. Kuphatikiza apo, pepala lakale lokutidwa ndi greaseproof limakutidwa ndi pulasitiki pamwamba pa pepalalo kudzera pamakina oponya. Popeza particles pulasitiki si degradable, izo zidzakhudza kwambiri chilengedwe. Pamene anthu amayang'anitsitsa kwambiri nkhani zoteteza chilengedwe, kugwiritsa ntchito mapepala opanda poizoni, osavulaza komanso owonongeka ndizomwe zimachitika.
