Muna 1956, Nelson naSeinberg veku Illinois vakaedzwa kuedza nemafirimu akawanda kusanganisira firimu repolyester. Kubva 1958, US Army Natick Institute uye SWIFT Institute vakatanga kudzidza chikafu chakapfava chemumagaba kuti mauto ashandise, kuti ashandise bhegi rakabikwa pachinzvimbo chetinplate chikafu chemumagaba munhandare yehondo, nhamba huru yekuyedza nekuita. miedzo. Chikafu chakapfava chemumagaba chakagadzirwa neNatick Institute muna 1969 chakavimbwa uye chakashandiswa zvakabudirira kuApollo Aerospace Program.
Muna 1968, iyo yeJapan Otsuka Chikafu Indasitiri Co., Ltd. inoshandisa yakajeka-yepamusoro-tembiricha yekudzosa bhegi yekurongedza curry chigadzirwa, uye yakawana kushambadzira muJapan. Muna 1969, iyo aluminium foil yakashandurwa sechinhu chakasvibiswa kuti chiwedzere kunaka kwebhegi, kuitira kuti kutengesa kwemusika kwakaramba kuchiwedzera; muna 1970, yakatanga kugadzira zvigadzirwa zvemupunga zvakaputirwa nemabhegi eretort; muna 1972, bhegi retort rakagadzirwa, uye kushambadzira, zvigadzirwa, The retort bagged meatballs zvakare yakaiswa mumusika.
Chihomwe chealuminium foil type retort chakatanga kugadzirwa nemitsara mitatu yezvinhu zvinodzivirira kupisa, zvinodaidzwa kuti “retort pouch” (RP for short), homwe yekudzosera inotengeswa neToyo Can Company yekuJapan, ine foil yealuminium inonzi RP-F (inoshingirira kusvika 135). ° C), akajeka akawanda-layer composite mabhegi asina aruminiyamu foil anonzi RP-T, RR-N (inodzivirira kusvika 120 ° C). Nyika dzeEurope neAmerica dzinodaidza bhegi iri kuti gaba rinochinjika (Flexible Can kana Soft Can).
Dzorera zvinhu zvehomwe
1. Inogona kuvharwa zvachose, microorganisms haingapindi, uye hupenyu hwesherufu hurefu. Bhegi rakajeka rine hupenyu hwesherufu inopfuura gore rimwe, uye aluminium foil type retort bag ine hupenyu hwesherufu hweanopfuura makore maviri.
2. Oxygen permeability uye hunyoro hwemvura huri pedyo ne zero, zvichiita kuti zvive zvisingabviri kuti zviri mukati zvigadzirise kuchinja kwemakemikari, uye zvinogona kuchengetedza kunaka kwezviri mukati kwenguva yakareba.
3. Iyo tekinoroji yekugadzira uye zvigadzirwa zvechikafu chemumagaba mumagaba esimbi uye mabhodhoro egirazi zvinogona kushandiswa.
4. Kuiswa chisimbiso kwakavimbika uye kuri nyore.
5. Bhegi rinogona kuvharwa nekupisa uye rinogona kurohwa neV-shaped uye U-shaped notches, izvo zviri nyore kubvarura uye kudya nemaoko.
6. Kushongedza kwekudhinda kwakanaka.
7. Inogona kudyiwa mushure mekupisa mukati memaminitsi matatu.
8. Inogona kuchengetwa pakamuri tembiricha uye inogona kudyiwa chero chiitiko.
9. Inokodzera kurongedza chikafu chitete, senge hove fillet, nyama fillet, nezvimwe.
10. Kurasa kuri nyore kubata.
11. Hukuru hwebhegi hunogona kusarudzwa mune zvakasiyana-siyana, kunyanya bhagi duku rekutakura bhegi, iro rinonyanya nyore kupfuura zvokudya zvekakani.
