Vacuum yekurongedza bhegi yakatanga kusimuka muma1940s, uyevacuum packaging bagsanoshandiswa zvakanyanya kurongedza nyama.Muna 1957, iyo yakatangira kambani yeQingdao Advanmatch Packaging Co., Ltd.akashandisa zviri pamutemo vacuum kurongedza mabhegi uye akatumira vacuum yekurongedza muchina.Vacuum packaged food ine nhoroondo inotevera: makore akapoteredza 1965, vacuum yakaputirwa bhinzi, vacuum packaged snacks, chikafu chakabikwa nechikafu chakaunzwa;Mushure me1967, vacuum yakarongedza hove dzakaomeswa, pickles, dumplings dzakaomeswa nechando, chingwa chakabikwa, salmon inoputa, salmon inoputa, kofi, mahamburger, mupunga wakabikwa, mupunga, nyama yakagochwa, chikafu chakabikwa nechando, mabhora enyama, nezvimwe zvakateedzana. akaunzwa.MuJapan, kufarirwa kwevacuum packaging kunotanga munyika, nepo munyika dzekumadokero, kunze kwenyama yakaomeswa nehove nechando, vacuum package yezvimwe zvikafu hazviwanzo.
Vacuum packagingine zvinotevera maitiro:
1.High barriers maitiro
Iyo firimu rinoshandiswa pakurongedza vacuum richava rimwechete rine yakanaka gasi kuramba, senge akasiyana PVDC coating mafirimu, PVDC OPP, PVDC pet, PVDC nylon, Eval firimu, naironi firimu uye PET firimu, akakodzera vacuum kurongedza mabhegi zvigadzirwa.Anenge ese masausage vacuum packaging anogadziriswa nekushandisa iyo inoumbwa firimu inogadzirwa nebiaxially yakatambanudzwa naironi firimu uye linear yakaderera-density polyethylene.Iyi firimu ine yakanaka yemhando yekuvimbisa nguva.Zvinenge zvese zvigadzirwa pasi, pasi zvipfeko uye pasi quilts vacuum yakazara nePVDC firimu seyakagadzirwa, iyo inogona kuderedza huwandu panguva yekufambisa uye kuchengetedza kutakura.
2. pinhole resistance
Pamusoro pekufunga nezve chipingamupinyi pfuma yezvinhu, chechipiri chinhu mukusarudzwa kwezvinhu uye dhizaini dhizaini ndeye pinhole kuramba.Chete chimiro chemidziyo chine yakanakisa pinhole kuramba chinogona kumira kukweshera uye pinholes inokonzerwa nekupeta panguva yekuzadza uye kupisa-kuisa chisimbiso kushanda, kutakura, kuchengetedza, kutengesa uye kushandisa.Ita kuti vacuum packaging isapinda mukati.Iyo vacuum yekurongedza zvinhu yakagadzirwa nebiaxial tensile nylon firimu uye linear yakaderera-density polyethylene firimu inogadzirwa nekambani yedu ine yakanaka pinhole kuramba, kusimba kwakasimba uye yakakwirira barriers zvivakwa.
