Kodi mitundu ya zinthu wamba yamakina otchuka ndi ziti?

Zithunzi za ①Poper-pulasitiki. Pepala ili ndi ntchito yosindikiza bwino, mpweya wabwino woperekera mphamvu, madzi osauka, ndi kusokonekera kwa kulumikizana ndi madzi; Kanema wa pulasitiki ali ndi madzi abwino ndi mpweya wabwino, koma kuwunika bwino. Pambuyo awiriwo ndi ophatikizika monga pepala la pulasitiki (filimu ya pulasitiki monga mawonekedwe), pepala-pulasitiki (pepala ngati mawonekedwe apansi), ndipo pepala la pulasitiki limapangidwa. Nkhani yophatikizira pulasitiki imatha kukonza chinyezi ndi chinyezi, ndipo nthawi yomweyo ili ndi ngozi yamoto. Itha kuphatikizidwa ndi njira yowuma, njira yonyowa yonyowa ndikukula.

Zithunzi za ②plastite. Zipangizo zamapulasitiki za pulasitiki ndizomwe zimadziwika kwambiri ndi zinthu zophatikizika. Makanema osiyanasiyana apulasitiki osiyanasiyana ali ndi zabwino zawo komanso zowawa zawo. Pambuyo powaphatikiza, zatsopanozi zili ndi zinthu zapamwamba monga kukana mafuta, kukana, komanso kupezeka panyanja. Pambuyo pa pulasitiki-pulasitiki, wosanjikiza awiri, atatu-osanjikiza, zinthu zinayi ndi zina zophatikizika zitha kupangidwa, monga: Otsutsa-pe.

Nkhani ya ③anuminim-phwitini. The air tightness and barrier properties of aluminum foil are better than that of plastic film, so sometimes a plastic-aluminum-plastic composite, such as PET-Al-PE, is used.

④Paper-aluminium-pulasitiki. Zinthu zophatikizika za pulasitiki zimagwiritsa ntchito kungokayikira kwa pepala, chinyezi chabwino komanso chochititsa manyazi cha aluminiyamu, ndi kutentha kwabwino kwa mafilimu ena. Kuphatikizana nawo limodzi titha kupeza zinthu zatsopano. Monga mapepala-aluminium-polyethylene.

Makina a fexoZiribe kanthu mtundu wa mtundu wa mitundu yanji yomwe ilipo, ikufunika kuti gawo labwino lakunja lili ndi zojambulajambula zabwino, ndipo mawonekedwe amkati ali ndi zinthu zomwe zilipo, chotchinga chotchinga, chotchinga chotere.
