Ukupakishwa kwe-vacuum kukutywina izixhobo emva kokuba umoya kwisikhwama sokupakisha ukhutshwe, ukuze ufezekise injongo yokugcina izinto ezintsha kunye nexesha elide lokupakishwa kwezinto ezipakishweyo, kwaye zilungele ukuthutha kunye nokugcinwa.Izixhobo zokupakisha i-vacuum ngumatshini osusa umoya ngaphakathi kwesikhongozeli emva kokuba imveliso ifakwe kwisingxobo sokupakisha, ifikelele kwiqondo elimiselweyo lokucoca (ngokuqhelekileyo malunga ne-2000 ~ 2500Pa) kwaye igqibe ukutywinwa.Isenokuzaliswa ngenitrogen okanye enye igesi exutyiweyo, kwaye emva koko ugqibezele inkqubo yokutywinwa.
Itekhnoloji yokupakisha iVacuum ikhona ukusukela ngoo-1940s.Kude kube phakathi kunye no-50s emva kwexesha, intsimi yokupakisha i-vacuum ngokuthe ngcembe yaqala ukusebenzisa i-polyethylene kunye nezinye iifilimu zeplastiki ukupakisha.Ekuqaleni kwe-1980, kunye nophuhliso olukhawulezayo lweshishini lokuthengisa kunye nokukhuthazwa ngokuthe ngcembe kwepakethe encinci, iteknoloji yasetyenziswa kwaye yaphuhliswa.Ukupakishwa kweVacuum kukulungele zonke iintlobo zeengxowa zefilimu ezidibeneyo zeplastiki okanye i-aluminium foil ehlanganisiweyo yeebhagi zefilimu, ezifana ne-polyester / i-polyethylene, i-nylon / i-polyethylene, i-polypropylene / i-polyethylene, i-polyester / i-aluminium foil / i-polyethylene, inayiloni / i-aluminium foil / i-polyethylene. .Ngokuphuculwa okuqhubekayo kolwazi lwabantu, ukusetyenziswa koomatshini bokupakisha i-vacuum kuye kwatsala ingqalelo engakumbi nangakumbi ekutyeni, kwilaphu, kwi-elektroniki nakwamanye amashishini.
Ngophuhliso oluqhubekayo lwenzululwazi kunye nobuchwepheshe kunye nokuphuculwa okuqhubekayo kwemigangatho yokuphila kwabantu, ukusetyenziswa kweteknoloji yokupakisha i-vacuum kuya kuba kuninzi kwaye kubanzi ngakumbi, kwaye iindidi, isimbo, ukusebenza kunye nomgangatho wezixhobo zokupakisha i-vacuum ziya kutshintsha kwaye ziphucule.Kwishishini lelaphu kunye nelezandla, ukupakishwa kwevacuum kunokunciphisa ngokufanelekileyo umthamo weemveliso kwaye kuququzelele ukupakishwa kunye nokuthutha;kwishishini lokutya, ukupakishwa kwe-vacuum kunye nenkqubo yokuvala inzala kunokuthintela ngokufanelekileyo ukuveliswa kwebhaktheriya, ukucotha ukonakala kokutya, kunye nokwandisa ubomi beshelufu yokutya;Kwishishini le-hardware, izixhobo ze-vacuum-packed hardware ziyakwazi ukwahlula i-oksijini, ukwenzela ukuba izixhobo zingafaki i-oxidize kunye nokugqwala.
Ukwakhiwa kwezixhobo zokupakisha i-vacuum yahlukile, kwaye indlela yokuhlela nayo yahlukile.Ngokuqhelekileyo, inokwahlulwa ibe yi-mechanical extrusion type, uhlobo lwe-intubation, uhlobo lwegumbi, njl njl ngokweendlela zokupakisha ezahlukeneyo;ngokwendlela izinto ezipakishweyo zingena ngayo kwigumbi, inokwahlulwa ibe yindlu enye, i-double-room, i-thermoforming, i-conveyor belt, i-rotary vacuum igumbi Ngokwendlela yokuhamba, inokwahlulwa ibe yintlobo ye-intermittent kunye nohlobo oluqhubekayo;ngokobudlelwane phakathi kwemveliso epakishiweyo kunye nesingxobo sokupakisha, inokwahlulwa ibe yipakethe yomzimba wevacuum kunye ne-vacuum inflatable packaging.
