Vacuum bagkunze kwekudzivisa kukura uye kubereka kwe microorganisms, rimwe basa rinokosha nderokudzivirira kusvibiswa kwezvokudya, nokuti mafuta nemafuta emafuta ane nhamba yakawanda yemafuta asina kukwana, basa reokisijeni uye oxidation, kuitira kuti zvokudya zvinonaka zvakaipa, kuora, kuwedzera, iyo oxidation yevhitamini A uye C kurasikirwa, kudya kwekudya mubasa rezvinhu zvisina kugadzikana neokisijeni, kuitira kuti ruvara rusvibe.Naizvozvo, kubviswa kweokisijeni kunogona kudzivirira kuparara kwechikafu uye kuchengetedza ruvara rwayo, kunhuhwirira, kuravira uye kukosha kwekudya.
Vacuum bagndeyekudzivirira zvigadzirwa kubva mukusvibiswa kwezvakatipoteredza uye kuwedzera hupenyu hwesherufu yekudya uye kumwe kurongedza, zvinogona kuvandudza kukosha uye kunaka kwezvigadzirwa.Vacuum packaging tekinoroji yakatanga muma1940s.Kubva 1950, polyester, polyethylene epurasitiki firimu yakabudirira kuiswa kune commodity kurongedza,vacuum packaging muchinayakagadziridzwa nokukurumidza.
Mumunda wehupenyu hwevanhu nebasa, zvakasiyana-siyana zvevacuum bag zvakawanda.Huremu, hwakanamwa, hutsva, anti-corrosion, rust-proof vacuum kurongedza mukati mechikafu kusvika kumishonga, zvigadzirwa zvakarukwa, kubva kune chaiyo kugadzira chigadzirwa kusvika kune simbi kugadzira zvidyarwa uye marabhoritari uye nezvimwe zvakawanda minda.Iko kuwedzera kupararira kwekushandiswa kwevacuum packaging kwakatungamira kuvandudzwa kwevacuum kurongedza michina, uye akaisawo mberi zvinodiwa zvepamusoro kwavari.
