Ukupakishwa kwe-vacuum ukuvala izinto zokwenziwa ngemva kokukhishwa komoya esikhwameni sokupakisha, ukuze kufezwe inhloso yokugcina izinto ezipakishiwe zisha nesikhathi eside, futhi kulungele ukuthuthwa nokugcinwa.Imishini yokupakisha i-vacuum ingumshini okhipha umoya ongaphakathi kwesitsha ngemva kokuba umkhiqizo ufakwe esitsheni sokupakisha, ufinyelele ku-vacuum degree enqunywe kusengaphambili (imvamisa engaba ngu-2000~2500Pa) bese uqedela ukuvala.Ingabuye igcwaliswe nge-nitrogen noma enye igesi exutshwe, bese uqedela inqubo yokuvala.
Ubuchwepheshe bokufaka i-vacuum bukhona kusukela ngawo-1940.Kuze kube maphakathi nama-50s ngasekupheleni, inkambu yokupakisha ye-vacuum kancane kancane yaqala ukusebenzisa i-polyethylene namanye amafilimu epulasitiki ukupakisha.Ekuqaleni kwawo-1980, ngokuthuthuka okusheshayo kwemboni yokudayisa kanye nokukhuthazwa kancane kancane kokupakishwa okuncane, ubuchwepheshe basetshenziswa futhi bathuthukiswa.Ukupakishwa kwe-vacuum kulungele zonke izinhlobo zezikhwama zefilimu eziyinhlanganisela yepulasitiki noma izikhwama zefilimu eziyinhlanganisela ye-aluminium foil, njenge-polyester / i-polyethylene, inayiloni / i-polyethylene, i-polypropylene / i-polyethylene, i-polyester / i-aluminium foil / i-polyethylene, inayiloni / i-aluminium foil / i-polyeriyali ye-polyeerial. .Ngokuthuthuka okuqhubekayo kokuqwashisa ngemibono yabantu, ukusetshenziswa kwemishini yokupakisha i-vacuum sekudonse ukunakwa okwengeziwe okuvela ekudleni, kwendwangu, kwezobuchwepheshe kanye nezinye izimboni.
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe kanye nokuthuthuka okuqhubekayo kwamazinga okuphila abantu, ukusetshenziswa kobuchwepheshe bokufaka i-vacuum kuzokwanda kakhulu, futhi ukuhlukahluka, isitayela, ukusebenza kanye nekhwalithi yemishini yokupakisha ye-vacuum kuzoshintsha futhi kuthuthuke.Embonini yendwangu kanye nemisebenzi yezandla, ukupakishwa kwe-vacuum kunganciphisa ngempumelelo umthamo wemikhiqizo futhi kube lula ukupakishwa nokuhamba;embonini yokudla, ukupakishwa kwe-vacuum kanye nenqubo yokuvala inzalo kungavimbela ngempumelelo ukukhiqizwa kwamagciwane, kubambezele ukubola kokudla, futhi kwandise impilo yeshalofu yokudla;Embonini ye-hardware, izesekeli ze-hardware ezigcwele i-vacuum zingahlukanisa umoya-mpilo, ukuze izesekeli zingafaki i-oxidize nokugqwala.
Isakhiwo semishini yokupakisha i-vacuum sihlukile, futhi indlela yokuhlukanisa nayo ihlukile.Ngokuvamile, ingahlukaniswa ibe uhlobo lwe-extrusion lwemishini, uhlobo lwe-intubation, uhlobo lwegumbi, njll ngokusho kwezindlela ezahlukene zokupakisha;ngokwendlela izinto ezihlanganisiwe ezingena ngayo ekamelweni, zingahlukaniswa zibe yi-single-chamber, i-double-chamber, i-thermoforming, i-conveyor belt, i-rotary vacuum chamber Ngokusho kwemodi yokunyakaza, ingahlukaniswa ngohlobo oluphakathi nohlobo oluqhubekayo;ngokuya ngobudlelwano phakathi komkhiqizo opakishiwe nesiqukathi sokupakisha, ingahlukaniswa ibe iphakethe le-vacuum yomzimba kanye nephakheji ye-vacuum inflatable.
