Ingxowa yokupakisha i-vacuum yavela kuqala kwi-1940s, kwayeiingxowa zokupakisha zevacuumzisetyenziswa kakhulu ukupakisha inyama.Ngowe-1957, inkampani eyandulelayoQingdao Advanmatch Packaging Co., Ltd.isetyenziswe ngokusemthethweni iingxowa zokupakisha ze-vacuum kwaye yagunyazisa umatshini wokupakisha we-vacuum.Ukutya okupakishwe ngevacuum kunembali ilandelayo: malunga no-1965, iimbotyi ezifunxiweyo ezifunxiweyo, i-vacuum packaged snacks, ukutya okuphekiweyo kunye nokutya okufakwe emanzini kwaqaliswa;Emva kowe-1967, ivacuum ipakishwe intlanzi eyomisiweyo, iipikhile, amadombolo akhenkcezisiweyo, iifillet zecod ezikhenkcezisiweyo, isonka esishushu, isalmon etshayiweyo, isalmon etshayiweyo, ikofu, iihambhega, irayisi ephekiweyo, irayisi, inyama eyosiweyo, ukutya okuphekiweyo okukwiqondo eliphezulu lobushushu, iibhola zenyama, njl. yaziswa.EJapan, ukuthandwa kokupakishwa kwevacuum kuqala kwihlabathi, ngelixa kumazwe asentshona, ngaphandle kwenyama ekhenkcezisiweyo kunye neentlanzi ezikhenkcezisiweyo, ukupakishwa kwevacuum kokunye ukutya kunqabile.
Ukupakishwa kwevacuuminezi mpawu zilandelayo:
1.Ukwenziwa komqobo ophezulu
Ifilimu esetyenziselwa ukupakishwa kwe-vacuum iya kuba yinto enokumelana negesi elungileyo, njengeefilimu ezahlukeneyo ze-PVDC zokugquma, i-PVDC OPP, i-PVDC pet, i-PVDC inayiloni, ifilimu ye-Eval, ifilimu yenylon kunye nefilimu ye-PET, efanelekileyo kwiimveliso zengxowa yokupakisha.Phantse yonke i-sausage vacuum packaging icutshungulwa ngokusebenzisa ifilimu edibeneyo eveliswe yifilimu yenayiloni eyoluliweyo ye-biaxially kunye ne-linear low-density polyethylene.Le filimu inexesha elihle lokuqinisekisa umgangatho.Phantse zonke iimveliso eziphantsi, iimpahla eziphantsi kunye ne-quilts eziphantsi zifakwe ifilimu ye-PVDC njengezinto eziluhlaza, ezinokunciphisa umthamo ngexesha lokuthutha kunye nokugcina imithwalo.
2. ukuxhathisa umngxuma
Ukongeza kokuqwalasela ipropati yesithintelo sezinto eziphathekayo, into yesibini ekukhethweni kwezinto eziphathekayo kunye noyilo lwesakhiwo kukuchasana kwe-pinhole.Isakhiwo sezinto eziphathekayo kuphela esinokumelana ne-pinhole egqwesileyo sinokumelana ne-friction kunye ne-pinholes ebangelwa ukugoqa ngexesha lokuzaliswa kunye nokutywinwa kokushisa, ukuthutha, ukugcinwa, ukuthengisa kunye nokusetyenziswa.Yenza ipakethe yevacuum ingangeni moya.Izinto zokupakisha ze-vacuum ezenziwe ngefilimu ye-nayiloni ye-biaxial tensile kunye nefilimu ye-polyethylene ephantsi yoxinaniso oluveliswe yinkampani yethu inokumelana ne-pinhole elungileyo, ukuqina olomeleleyo kunye nepropathi yomqobo ephezulu.
