Chikwama cham'mbali chachitatu chimagwiritsidwa ntchito kwambiri pakuyika chakudya, thumba la vacuum, thumba la mpunga, thumba loyima, thumba la chigoba, thumba la tiyi, thumba la maswiti, thumba la ufa, thumba la zodzikongoletsera, thumba la akamwemwe, thumba lamankhwala, thumba la mankhwala ophera tizilombo ndi zina zotero.
Imirirani thumba lokha chibadidwe chinyezi-umboni ndi madzi, njenjete-umboni, odana ndi zinthu anamwazikana ubwino, kuti kuimirira thumba chimagwiritsidwa ntchito ma CD mankhwala, kusungirako mankhwala, zodzoladzola, chakudya, chakudya mazira ndi zina zotero.
Aluminiyamu zojambulazo thumba ndi oyenera ma CD chakudya, mpunga, nyama, tiyi, khofi, nyama, anachiritsa mankhwala, soseji, nyama yophika, pickles, nyemba phala, zokometsera, etc., akhoza kukhalabe kukoma kwa chakudya kwa nthawi yaitali. , bweretsani chakudya chabwino kwambiri kwa ogula.
Aluminiyamu zojambulazo zonyamula katundu wabwino wamakina, kotero kuti imagwiranso ntchito bwino pamakina, hard disk, PC board, LIQUID crystal display, zida zamagetsi, zotengera zotayidwa za aluminiyamu ndizokonda.
Mapazi a nkhuku, mapiko, zigongono ndi nyama zina zokhala ndi mafupa zimakhala ndi zolimba zolimba, zomwe zimabweretsa kupsinjika kwakukulu kwa thumba lazonyamula pambuyo pa vacuum.Choncho, tikulimbikitsidwa kuti tisankhe zipangizo zomwe zili ndi makina abwino a matumba osungiramo vacuum a zakudya zotere kuti tipewe ma punctures panthawi yoyendetsa ndi kusunga.Mukhoza kusankha PET/PA/PE kapena OPET/OPA/CPP vacuum bags.Ngati kulemera kwa mankhwala ndi zosakwana 500g, mungayesere kugwiritsa ntchito OPA/OPA/PE dongosolo thumba, thumba ili bwino mankhwala kusinthika, zotsatira vacuuming bwino, ndipo sadzasintha mawonekedwe a mankhwala.
Soya mankhwala, soseji ndi zinthu zina zofewa pamwamba kapena osasamba mawonekedwe, ma CD kutsindika pa chotchinga ndi njira yolera yotseketsa, mawotchi katundu wa zinthu si mkulu zofunika.Pazinthu zotere, zikwama zonyamula vacuum za kapangidwe ka OPA/PE zimagwiritsidwa ntchito nthawi zambiri.Ngati kutentha kwakukulu kumafunika (pamwamba pa 100 ℃), mawonekedwe a OPA/CPP angagwiritsidwe ntchito, kapena PE yokhala ndi kutentha kwambiri ingagwiritsidwe ntchito ngati chosindikizira kutentha.
