Kugwiritsa ntchito pepala lopangidwa ndi dongo la PE

Kufotokozera Kwachidule:

Pepala lopaka dongo la PE, lomwe limadziwikanso kuti pepala ladongo lopangidwa ndi polyethylene, ndi mtundu wa pepala lokutidwa lomwe lili ndi nsanjika ya polyethylene (PE) pamwamba pa dongo.

Titumizireni imelo

Tsatanetsatane wa Zamalonda

Zolemba Zamalonda

Pepala lamtunduwu lili ndi ntchito zingapo, zina mwazo ndi:
1. Kupaka chakudya: Mapepala opaka dongo a PE amagwiritsidwa ntchito kwambiri popanga zakudya chifukwa cha chinyezi komanso kusamva mafuta. Amagwiritsidwa ntchito kwambiri kukulunga zakudya monga burgers, masangweji, ndi zokazinga za ku France.
2. Zolemba ndi ma tag: Mapepala opangidwa ndi dongo la PE ndi abwino kwambiri kwa zilembo ndi ma tag chifukwa cha malo ake osalala, omwe amalola kusindikiza kukhala akuthwa komanso momveka bwino. Amagwiritsidwa ntchito kwambiri pazolemba zamalonda, ma tag amitengo, ndi ma barcode.
3. Kuyika kwachipatala: Mapepala opangidwa ndi dongo la PE amagwiritsidwanso ntchito m'mapaketi achipatala chifukwa amapereka chotchinga ku chinyezi ndi zonyansa zina, kuteteza kuipitsidwa kwa chipangizo chachipatala kapena zipangizo.
4. Mabuku ndi magazini: Pepala lokutidwa ndi dongo la PE nthawi zambiri limagwiritsidwa ntchito popanga zofalitsa zapamwamba kwambiri monga mabuku ndi magazini chifukwa cha kumaliza kwake kosalala komanso konyezimira, zomwe zimakulitsa luso losindikiza.
5. Pepala lokulunga: Pepala lokutidwa ndi dongo la PE limagwiritsidwanso ntchito ngati mapepala omangira mphatso ndi zinthu zina chifukwa cha zinthu zosagwira madzi, zomwe zimapangitsa kuti zikhale zoyenera kukulunga zinthu zowonongeka monga maluwa ndi zipatso.
Ponseponse, pepala lokutidwa ndi dongo la PE ndizinthu zosunthika zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana.

Ubwino wa pepala lopangidwa ndi dongo la PE

Pepala lokutidwa ndi dongo la PE lili ndi zabwino zingapo, kuphatikiza:
1. Kukana kwa chinyezi: Kupaka kwa PE pamapepala kumapereka kukana kwa chinyezi, ndikupangitsa kuti ikhale yabwino kuti igwiritsidwe ntchito pamapaketi omwe zilimo ziyenera kutetezedwa ku chinyezi.
2. Kukaniza mafuta: Pepala lopaka dongo la PE limalimbananso ndi mafuta, zomwe zimapangitsa kukhala chisankho chabwino kwambiri pazopaka zakudya zomwe zimafunikira kuti mafuta asalowe m'mapepala.
3. Malo osalala: Pa pepala lokutidwa ndi dongo ladongo limapereka kutha kosalala komwe kumapangitsa kuti ntchito yosindikiza ikhale yabwino kwambiri, ndikupangitsa kuti ikhale yoyenera kusindikiza kwapamwamba kwambiri monga magazini ndi mabuku.
4. Chokhazikika: Pepala lopangidwa ndi dongo la PE limakhalanso lolimba komanso losagwetsa misozi, zomwe zimapangitsa kuti zikhale zoyenera kuyikapo zomwe zilimo ziyenera kutetezedwa panthawi yogwira ndi kuyendetsa.
5. Zokhazikika: Pepala lokutidwa ndi dongo la PE litha kupangidwa kuchokera kuzinthu zokhala ndi gwero lokhazikika, zomwe zimapangitsa kuti ikhale njira yosungira bwino zachilengedwe.
Ponseponse, zabwino za pepala lokutidwa ndi dongo la PE zimapangitsa kukhala chisankho chodziwika bwino m'mafakitale osiyanasiyana, kuphatikiza kulongedza zakudya, kulemba zilembo, kuyika zachipatala, ndi zofalitsa.
