Isikhwama sokupakisha se-vacuum saqala ukuvela ngawo-1940, futhiizikhwama zokupakisha ze-vacuumasetshenziswa kakhulu ukupakisha inyama.Ngo-1957, inkampani eyandulelaI-Qingdao Advanmatch Packaging Co., Ltd.izikhwama zokupakisha ze-vacuum ezisetshenziswe ngokusemthethweni futhi zagunyaza umshini wokupakisha we-vacuum.Ukudla okupakishwe ngevacuum kunomlando olandelayo: ngonyaka ka-1965, kwethulwa ubhontshisi obufakwe ngesitimu, izibiliboco ezipakishwe ngevacuum, ukudla okuphekiwe kanye nokudla okufakwe emanzini anosawoti;Ngemva kuka-1967, i-vacuum ihlanganiswe nezinhlanzi ezomisiwe, amakhukhamba, amadombolo afriziwe, izibopho ze-cod eziqandisiwe, isinkwa esishisayo, i-salmon ebhemayo, i-salmon ebhemayo, ikhofi, ama-hamburgers, irayisi eliphekiwe, irayisi, inyama eyosiwe, ukudla okuphekwe ngokushisa okuphezulu, ama-meatballs, njll. yethulwe.EJapane, ukuthandwa kokufakwa kwe-vacuum kuqala emhlabeni, kuyilapho emazweni asentshonalanga, ngaphandle kwenyama eqandisiwe nezinhlanzi eziqandisiwe, ukupakishwa kwe-vacuum kokunye ukudla akuvamile.
Ukupakisha kwe-vacuuminezici ezilandelayo:
1.High barrier ukusebenza
Ifilimu esetshenziselwa ukupakisha i-vacuum izoba ngeyokumelana kahle negesi, njengamafilimu ahlukahlukene e-PVDC enamathela, i-PVDC OPP, isilwane esifuywayo se-PVDC, inayiloni ye-PVDC, ifilimu ye-Eval, ifilimu yenayiloni nefilimu ye-PET, afanele imikhiqizo yesikhwama se-vacuum.Cishe wonke amaphakheji evacuum amasoseji acutshungulwa kusetshenziswa ifilimu eyinhlanganisela ekhiqizwe ifilimu enayiloni eyelulwe nge-biaxially kanye ne-linear low density polyethylene.Le filimu inesikhathi sokuqinisekisa ikhwalithi enhle.Cishe yonke imikhiqizo ephansi, izingubo eziphansi kanye nezindwangu zaphansi ziyi-vacuum egcwele ifilimu ye-PVDC njengezinto zokusetshenziswa, ezinganciphisa ivolumu ngesikhathi sokuthutha futhi zonge impahla.
2. ukumelana ne-pinhole
Ngaphezu kokucabangela impahla yesithiyo yezinto zokwakha, isici sesibili ekukhethweni kwezinto ezibonakalayo kanye nokwakhiwa kwesakhiwo ukuphikiswa kwe-pinhole.Isakhiwo sezinto ezibonakalayo kuphela esinokumelana okuhle kakhulu kwe-pinhole singamelana nokungqubuzana kanye nezimbobo zokukhonkwane ezibangelwa ukugoqa ngesikhathi sokugcwalisa nokufaka uphawu lokushisa, ukuthutha, ukugcinwa, ukuthengisa nokusetshenziswa.Yenza iphakethe levacuum lingangeni moya.Izinto zokupakisha ze-vacuum ezenziwe ngefilimu enayiloni ye-biaxial tensile kanye nefilimu ye-polyethylene ene-low-density ekhiqizwe inkampani yethu inokumelana ne-pinhole okuhle, ukuqina okuqinile kanye nempahla ephezulu yokuvimbela.
