Kagwiritsidwe ntchito ndi makhalidwe a pepala la chimbudzi ndi pepala lokhala ndi makoko

Pepala la chimbudzi, lomwe limadziwikanso kuti pepala la chimbudzi la crepe, limagwiritsidwa ntchito kwambiri pa thanzi la anthu tsiku ndi tsiku ndipo ndi limodzi mwa mitundu yofunika kwambiri ya mapepala kwa anthu. Pofuna kufewetsa pepala la chimbudzi, kufewa kwa pepala la chimbudzi kumawonjezeka pokwinya pepalalo pogwiritsa ntchito makina. Pali zinthu zambiri zopangira pepala la chimbudzi, zomwe zimagwiritsidwa ntchito kwambiri ndi thonje, matabwa, udzu, mapepala otayira ndi zina zotero. Sikofunikira kukula kwa pepala la chimbudzi. Ngati pepala la chimbudzi lamitundu yosiyanasiyana lapangidwa, utoto wokonzedwa uyenera kuwonjezeredwa. Pepala la chimbudzi limadziwika ndi kuyamwa madzi mwamphamvu, kuchuluka kwa mabakiteriya ochepa (chiwerengero chonse cha mabakiteriya pa gramu imodzi ya kulemera kwa pepala sikuyenera kupitirira 200-400, ndipo mabakiteriya opatsirana monga mabakiteriya a coliform saloledwa), pepalalo ndi lofewa, lolimba mofanana, lopanda mabowo, komanso lopindika mofanana, Mtundu wokhazikika komanso zodetsa zochepa. Ngati likupanga mipukutu yaying'ono ya pepala la chimbudzi la magawo awiri, mtunda wa mabowo uyenera kukhala wofanana, ndipo mabowo a pinbowo ayenera kukhala omveka bwino, osweka mosavuta komanso oyera.

Pepala loyambira lokhala ndi corrugated ndi pepala loyambira lopangidwa ndi corrugated, lomwe limagwiritsidwa ntchito makamaka pakupanga pakati pa katoni yozungulira. Mapepala ambiri ozungulira opangidwa ndi corrugated amapangidwa ndi mpunga wopangidwa ndi laimu ndi udzu wa tirigu, ndipo kuchuluka komwe kumagwiritsidwa ntchito kwambiri ndi 160 g/m2, 180 g/m2, ndi 200 g/m2. Zofunikira pa pepala lozungulira ndi ulusi wofanana, makulidwe ofanana a mapepala, ndi mphamvu zina monga kupanikizika kwa mphete, mphamvu yokoka, ndi kukana kupindika. Silisweka mukakanikiza pepala lozungulira, ndipo limakhala ndi kukana kwakukulu kwa kuthamanga. Ndipo lili ndi kuuma kwabwino komanso kupuma bwino. Mtundu wa pepalalo ndi wachikasu wowala, wosalala, ndipo chinyezi ndi choyenera.
