Pepala lachakudya ndilopangidwa kuchokera ku zinthu zakuthambo - cellulose. Chifukwa cha izi, popanda nkhawa, mapepalawa angagwiritsidwe ntchito popangira chakudya, makamaka kuphika, mafuta , nyama zopangidwa ndi mankhwala osakaniza kapena zowonongeka kuti ziike mufiriji kapena firiji. Amatchedwanso zikopa.
Pofuna kugwiritsa ntchito mapepala zakudya zimatipindulitsa kuti:
- chiyanjano ndi chisangalalo;
- chinyezi, mafuta ndi mpweya;
- mphamvu.
Choncho, mapepala ophikira chakudya amathandiza kuti mankhwala "apume," koma palibe kutuluka kwa madzi ndi mpweya. Kuonjezera apo, chakudya mu zikopa sichipeza zokonda kapena fungo losakaniza.
