Kuyika kwa vacuum ndikusindikiza zinthuzo mutatha kutulutsa mpweya m'thumba, kuti mukwaniritse cholinga chosungira zinthu zatsopano komanso nthawi yayitali, ndipo ndi yabwino mayendedwe ndi kusungirako.Zida zoyikamo vacuum ndi makina omwe amachotsa mpweya mkati mwa chidebecho chikayikidwa mumtsuko, kufika pa digiri ya vacuum yokonzedweratu (nthawi zambiri pafupifupi 2000 ~ 2500Pa) ndikumaliza kusindikiza.Ikhozanso kudzazidwa ndi nayitrogeni kapena gasi wina wosakanizidwa, ndiyeno malizitsani kusindikiza.
Tekinoloje yonyamula vacuum yakhalapo kuyambira 1940s.Mpaka pakati ndi mochedwa 50s, ndi vakuyumu ma CD munda pang'onopang'ono anayamba kugwiritsa ntchito polyethylene ndi mafilimu ena pulasitiki ma CD.Kumayambiriro kwa zaka za m'ma 1980, ndi chitukuko chofulumira cha malonda ogulitsa ndi kukwezedwa pang'onopang'ono kwa ma CD ang'onoang'ono, teknoloji inagwiritsidwa ntchito ndikupangidwa.Vacuum ma CD ndi oyenera mitundu yonse ya matumba pulasitiki gulu filimu kapena zotayidwa zojambulazo gulu filimu matumba, monga poliyesitala / polyethylene, nayiloni / polyethylene, polypropylene / polyethylene, poliyesitala / zotayidwa zojambulazo / polyethylene, nayiloni / aluminium zojambulazo / polyethylene. .Ndi kusintha kosalekeza kwa kuzindikira kwa malingaliro a anthu, kugwiritsa ntchito makina odzaza vacuum kwakopa chidwi chochulukirapo kuchokera ku zakudya, nsalu, zamagetsi ndi mafakitale ena.
Ndi chitukuko chosalekeza cha sayansi ndi ukadaulo komanso kupititsa patsogolo moyo wa anthu, kugwiritsa ntchito ukadaulo wapa paketi ya vacuum kudzachulukirachulukira, ndipo mitundu, mawonekedwe, magwiridwe antchito ndi mtundu wa zida zonyamula vacuum zidzasintha ndikuwongolera.M'makampani opanga nsalu ndi manja, kuyika kwa vacuum kumatha kuchepetsa kuchuluka kwazinthu ndikuwongolera kulongedza ndi mayendedwe;m'makampani azakudya, kuyika kwa vacuum ndi kutseketsa kumatha kuletsa kubereka kwa mabakiteriya, kuchepetsa kuwonongeka kwa chakudya, ndikuwonjezera moyo wa alumali wachakudya;M'makampani a hardware, zida za hardware zodzaza ndi vacuum zimatha kudzipatula mpweya, kuti zowonjezera zisawonongeke ndi dzimbiri.
Mapangidwe a zida zonyamula vacuum ndizosiyana, ndipo njira yogawa ndi yosiyana.Kawirikawiri, akhoza kugawidwa mu makina extrusion mtundu, intubation mtundu, chipinda mtundu, etc. malinga ma CD njira zosiyanasiyana;molingana ndi momwe zinthu zomwe zimapakidwa zimalowera m'chipindacho, zimatha kugawidwa m'chipinda chimodzi, chipinda chachiwiri, thermoforming, lamba woyendetsa, chipinda chopukutira chozungulira Malinga ndi kayendetsedwe ka kayendetsedwe kake, chikhoza kugawidwa m'magulu apakati ndi mtundu wopitirira;molingana ndi ubale pakati pa zomwe zapakidwa ndi chidebe choyikamo, zitha kugawidwa m'mapaketi a vacuum body and vacuum inflatable ma CD.
