Chikwama Chakudya Cha Ziweto

Pakadali pano, matumba onyamula zakudya owuma pamsika amatha kugawidwa m'matumba akusanjikiza amodzi, matumba ophatikizika, ndi matumba onyamula amitundu yambiri. Pulasitiki yofewa yophatikizika imagwiritsidwa ntchito kwambiri m'matumba oyika zakudya owuma, ndipo matumba amtundu uwu woyikira zakudya amakhalanso ndi zophatikizira zambiri pamapangidwe azinthu.

Malinga ndi zomwe zili, pali mitundu ingapo yomwe ingagwiritsidwe ntchito poyika chakudya chozizira. Chimodzi, PET/PE. Kapangidwe kazinthu kameneka kamakhala kofala kwambiri pakuyika zakudya zozizira msanga. Imakhala ndi kukana kwabwino kwa chinyezi, kukana kuzizira, komanso kusindikiza kutentha kwapang'onopang'ono, ndipo mtengo wake ndi wotsika kwambiri.

Chachiwiri, BOPP/PE ndi BOPP/CPP. Matumba oyikamo chakudya owuma azinthu ziwirizi amakhala ndi mphamvu yolimbana ndi chinyezi komanso kuzizira, kutsika kwamphamvu kwamphamvu yotseka kutentha, komanso chuma chabwino. Ndikoyenera kutchula kuti zinthu za BOPP/PE zimamveka bwino kuposa PET/PE, zomwe ndi zabwino kutsatsa malonda.

Chachitatu, PET/VMPET/CPE, BOPP/VMPET/CPE. Poyerekeza ndi matumba oyikapo osanjikiza amodzi komanso awiri, mawonekedwe a magawo atatu amakhala olimba komanso okhazikika, ndipo amakhala ndi zotchinga zapamwamba. Komanso, kukhalapo kwa aluminiyamu wosanjikiza kumakhalanso ndi mwayi wodziwika bwino pakusindikiza. Komabe, poyerekeza ndi zipangizo zomwe zili pamwambazi, kutentha kwapansi kutentha Kusasindikiza bwino komanso mtengo wapamwamba Chachinayi, PA/PE, PET/PA/LLDPE, PET/PA/AL/PE, PA/PE. Mapangidwe a mitundu inayi ya zida izi ndi osagwirizana kwambiri ndi kuzizira komanso kukhudzidwa, ndipo gawo la PA limatsimikizira kukana kwabwino kwa puncture. Choyipa chake ndichakuti mtengo wake ndi wokwera, ndipo nthawi zambiri umagwiritsidwa ntchito popakira chakudya chambiri kapena cholemetsa.
