Kodi pali kusiyana kotani pakati pa pepala lokutidwa ndi pepala lopaka utoto?

Kupaka utoto kumapangidwa pothira filimu yamadzimadzi papepala ndikuumitsa. Mtengo wa utotowo ndi wotsika, koma zofunikira pa pepala loyambira ndi zapamwamba, ndipo pepala wamba silingathe kuphimbidwa. Njira yopangira pepala lopaka utoto imapangidwa pothira filimu yamadzimadzi, yomwe nthawi zambiri imakhala ndi mphamvu yosalowa madzi. Makapu a pepala ndiye chitsanzo chabwino kwambiri.

Kupaka utoto kumatanthauza kugwiritsa ntchito filimu yapulasitiki yowonekera pamwamba pa zinthu zosindikizidwa pokanikiza motentha. Filimu yotenthetsera ndi yopyapyala, imakhala ndi kuwala kwabwino, ndipo imasungidwa kwa nthawi yayitali. Ili ndi zofunikira zochepa papepala, koma mtengo wake ndi wokwera. Kupaka utoto ukalephera, filimuyo singathe kuchotsedwa. Nthawi zambiri imagwiritsidwa ntchito posindikiza, kupanga kamodzi kokha, monga momwe dzinalo likusonyezera, kumaphimba pamwamba pa inki, ndipo sikophweka kuipitsa.

Pepala lophimbidwa nthawi zambiri limagwiritsidwa ntchito popangira zinthu. Mwachitsanzo, zinthu zopangira mapepala otsatsa malonda amakampani ndi pepala lokhala ndi mbali imodzi lokhala ndi PE, ndipo mkati mwake simulowa madzi kudzera mu wosanjikiza wophimbidwa. Imatha kusunga madzi kwa nthawi yayitali popanda kutuluka ndi kutuluka madzi, zomwe zimapangitsa kuti khoma la chikho cha pepala likhale lolimba. Zopangira zake nthawi zambiri zimakhala polyethylene.

Mpukutu wa Pepala Wokutidwa ndi PE

Makanema opakidwa utoto amagawidwa m'magawo onyezimira kapena opakidwa utoto wa matte, omwe nthawi zambiri amagwiritsidwa ntchito posindikiza mabizinesi amakampani, monga zinthu zosindikizidwa zomwe zimagwiritsidwa ntchito kwambiri pamakampani: makadi abizinesi, mafoda, masamba amodzi, zivundikiro za ma album, malo osungira zinthu, ndi zina zotero. Zinthu zomwe zili mufilimuyi nthawi zambiri zimakhala PET (polyethylene terephthalate). Pambuyo posindikiza, imalumikizidwa ku pepala, zomwe zimapangitsa kuti zinthu zosindikizidwazo zizikhala nthawi yayitali, nthawi yomweyo, imagwira ntchito yoteteza chinyezi, yosalowa madzi, yosatha, komanso yosapindika, zomwe zingathandize wogwiritsa ntchito kudziwa zambiri ndikukweza mtundu wa zinthu zosindikizidwa.
