Chikwama chosungiramo zipper chosungiramo zinthu zobwezerezedwanso chomwe chimapangidwa ndi pulasitiki

Matumba akunja ophikira chakudya amagwiritsanso ntchito zinthu zosiyanasiyana, zomwe zambiri zimagwiritsa ntchito matumba apulasitiki ophikira zinthu, chifukwa matumba apulasitiki ophikira ndi opepuka, ali ndi zotsatira zabwino zosindikizira, ndipo ndi osavuta kusunga ndi kunyamula.

Zipu ya thumba la zipu lodziyimira lokha ingagwiritsidwenso ntchito kuteteza chakudya kuti chisawonongeke ndi chinyezi. Ili ndi ubwino waukulu kwambiri.

Mwachitsanzo: zipatso zouma, mtedza, zokometsera zouma, chakudya cha ufa, ndi chakudya chomwe sichingadyedwe nthawi imodzi, ambiri mwa iwo amagwiritsa ntchito matumba apulasitiki okhala ndi zipu kapena matumba apulasitiki odzimamatira okha okhala ndi guluu. Matumba olongedza chakudya okhala ndi zipu ndi matumba apulasitiki odzimamatira okha ndi matumba olongedza apulasitiki. Thumba likatsegulidwa, limatha kutsekedwa kawiri. Ngakhale silingathe kukwaniritsa zotsatira za kutsekedwa koyamba, lingagwiritsidwe ntchito ngati loletsa chinyezi komanso fumbi tsiku ndi tsiku kwakanthawi kochepa. Zingathekebe.

Chikwama choyimirira chimatanthauza chikwama chopakira chosinthasintha chokhala ndi kapangidwe kowongoka kochirikiza pansi, chomwe sichidalira chithandizo chilichonse ndipo chimatha kuyimirira chokha mosasamala kanthu kuti chikwamacho chatsegulidwa kapena ayi. Chikwama choyimirira ndi njira yatsopano yopakira, yomwe ili ndi ubwino wokweza khalidwe la chinthu, kulimbitsa mawonekedwe a mashelufu, kunyamulika, kosavuta kugwiritsa ntchito, kusungidwa mwatsopano komanso kutsekeka.

Kuphatikiza ziwirizi, thumba la zipi lodzichirikiza lokha linaonekera. Gwiritsani ntchito mawonekedwe omwe ali pamwambapa, ndikusankha zinthuzo, zomwe nthawi zambiri zimakhala ndi kapangidwe ka PET/foil/PET/PE, ndipo zitha kukhala ndi zigawo ziwiri, zigawo zitatu ndi zina zomwe zimagwiritsidwa ntchito pazinthuzo, kutengera zinthu zosiyanasiyana zomwe zili mu phukusili, zitha kuwonjezeredwa ngati pakufunika. Chida choteteza mpweya chimachepetsa kulowa kwa mpweya kuti chikhale ndi zotsatira zabwino zotalikitsa nthawi yogwiritsira ntchito.
