Ifilimu Yokumboza Okuphezulu PET/PE Yokupakisha Ukudla

Ifilimu Yokumboza Okuphezulu PET/PE Yokupakisha Ukudla

Ifilimu ye-lamination ye-HSQY ephezulu PET/PE ihlanganisa ungqimba lwangaphandle PET lwamandla omshini, ukuzinza kobukhulu kanye nokuphrinta ngengqimba yokuvala ye-PE yokuguquguquka kanye nokuvala ukushisa. Izinketho zokuvimbela ezibalwe ohlwini lomkhiqizo wamanje zifaka ubuchwepheshe be-EVOH kanye PVDC bezinhlelo zokupakisha ukudla ezidinga ukuvikelwa okuthuthukisiwe ngokumelene nomoya-mpilo, umswakama kanye nokudluliswa kwephunga.

Ububanzi bamanje buyatholakala ngobukhulu obungaba ngu-45-350μm kanye nobubanzi obungu-160-2600mm, nefilimu ecacile kanye nezinketho zokuphrinta imibala ezingu-1-13. Kungahlolwa ngokupakishwa kwe-vacuum, ukupakishwa kwe-atmosphere okuguquliwe, inyama, inhlanzi, ukudla kwasolwandle, imikhiqizo yobisi, ikhofi, ukudla okulula kanye nokunye ukudla okuzwela umoya-mpilo noma umswakama.

Ukusebenza kwezithiyo eziphakeme kuncike esakhiweni se-laminate esiqondile, ungqimba lwesithiyo, ukujiya okuphelele, ungqimba lwesithiyo kanye nezimo zokuhlola. I-OTR yokugcina, i-WVTR, amandla esitiyo, ukuhambisana kokucubungula ukushisa kanye nokusebenza kwesikhathi seshelufu kufanele kuqinisekiswe ukuze kuqinisekiswe ukucaciswa kwefilimu okuvunyiwe kanye nokudla okupakishwe kwangempela.

Imininingwane yefilimu ye-High Barrier PET/PE Lamination

Inothi Lobuchwepheshe: Ulwazi lwamanje lomkhiqizo alushicileli i-OTR, i-WVTR, izinga lokushisa lokuqalisa uphawu, amandla ophawu, amandla e-laminate bond, ububanzi be-roll core, i-OD ephezulu yomqulu noma imikhawulo yokucubungula ukushisa. Lawa manani kufanele aqinisekiswe ngokwakhiwa okuqondile okusetshenziswe ephaketheni lokugcina.

Isakhiwo se-Laminate esingu PET/PE

PET kanye ne-PE zenza imisebenzi ehlukene ngaphakathi kwe-laminate eguquguqukayo. Ukuzihlanganisa kuvumela umklami wephakheji ukuthi alinganisele ukuqina, ukuphrinta, amandla omshini, ukuvala kanye nokusebenza kwesithiyo.

Inketho ye-EVOH High-Barrier

I-EVOH isetshenziswa kabanzi njengento yokuvimbela umoya-mpilo ezakhiweni zokupakisha ukudla ezinezingqimba eziningi. Uma ivikelwe ngaphakathi kwe-laminate, inganciphisa kakhulu ukudluliswa komoya-mpilo uma kuqhathaniswa nesakhiwo esijwayelekile PET/PE .

Ukusebenza kwesithiyo se-EVOH kuthintwa umswakama, ukujiya kwesendlalelo kanye nomklamo ophelele we-laminate. Ngenxa yalesi sizathu, umkhiqizo ochazwa kuphela ngokuthi ' PET/PE /EVOH' awunikezi ulwazi olwanele lokubikezela isikhathi seshelufu lephakheji ngaphandle kwencazelo yangempela ye-OTR kanye nezimo zokuhlola.

PVDC High-Barrier

PVDC ibhekiselwa futhi ekucacisweni komkhiqizo we-HSQY njengamanje njengobuchwepheshe obunezithiyo eziphakeme. Inganikeza ukusebenza okuqinile komoya-mpilo, iphunga kanye nokusebenza komswakama uma isetshenziswa esakhiweni esifanele sokupakisha.

Ukucushwa okuqondile PVDC kanye nokwakhiwa kwe-coating noma i-laminate akushicilelwe ekhasini lamanje. Abathengi abadinga isakhiwo se- PVDC kufanele bacele imininingwane yengqimba ehambisanayo, ulwazi lwe-coating lapho kufanele khona, i-OTR, i-WVTR kanye nemibhalo yokuxhumana nokudla.

Ifilimu Ejwayelekile PET/PE vs. High-Barrier PET/PE

Ukuqonda i-OTR Yokupakisha Ukudla Okunezithiyo Eziphezulu

I-OTR, noma izinga lokudluliselwa komoya-mpilo, ingenye yezincazelo ezibaluleke kakhulu lapho ukhetha ifilimu lokupakisha ukudla elinomkhawulo ophezulu. Ibonisa ukuthi ingakanani i-oxygen engadlula ezintweni ngaphansi kwezimo zokuhlola ezichaziwe.

I-OTR ephansi ngokuvamile inikeza ukuvikelwa okuqinile komoya-mpilo, kodwa inani le-OTR lisho kuphela uma izinga lokushisa lokuhlola, umswakama ohlobene, ukujiya kwezinto kanye nezinga lokuhlola nakho kushiwo.

Ikhasi lamanje le-HSQY alishicileli inani elilodwa le-OTR. Abathengi kufanele banikeze i-OTR yabo eqondiwe noma imfuneko yokuphila kweshelufu lokudla okupakishiwe ukuze isakhiwo esifanelekile sesithintelo sihlolwe.

Ukuqonda i-WVTR yokuvikela umswakama

I-WVTR ichaza izinga lapho umhwamuko wamanzi udlula khona efilimini ngaphansi kwezimo ezichaziwe. Kungabaluleka ekudleni lapho ukuzuza komswakama noma ukulahleka komswakama kuthinta khona ukuthungwa, ikhwalithi noma isikhathi sokuphelelwa yisikhathi.

Ikhofi, ukudla okomile, imikhiqizo yokubhaka, imikhiqizo yobisi kanye nokunye ukudla okuzwela umswakama kungadinga izinhloso ezahlukene zokuvimbela umswakama. Ngakho-ke, iphakheji ephelele kufanele ikhethwe ngokuya ngomkhiqizo wangempela kunokuba ithathwe encazelweni ejwayelekile 'yesithiyo esikhulu'.

Ifilimu Enezithiyo Eziphezulu Yokupakishwa Komoya Okuguquliwe

Ukupakishwa kwesimo sezulu okuguquliwe kuthatha indawo noma kuguqula ukwakheka kwegesi ngaphakathi kwephakheji ukuze kusekelwe ikhwalithi yomkhiqizo kanye nesikhathi sokuphelelwa yisikhathi.

Kuzinhlelo zokusebenza ze- MAP , ifilimu idinga ukusebenza nohlelo oluphelele lwephakheji. Isithiyo sefilimu, ungqimba lokuvala, isakhiwo ithileyi noma sesikhwama, ingxube yegesi, isikhala sephakheji, izinga lokushisa lokugcina kanye nobuqotho be-seal konke kuthinta ukugcinwa kwegesi.

Abathengi kufanele banikeze ukudla okupakishiwe, ingxube yegesi edingekayo kanye nesikhathi sokuphelelwa yisikhathi lapho becela isakhiwo se PET/PE esinomkhawulo ophezulu se MAP .

Ifilimu Evimbelayo Ephakeme Yokupakisha I-Vacuum

Ukupakisha nge-vacuum cleaner kususa umoya ephaketheni ngaphambi kokuvala futhi kungasetshenziswa enyameni, ekudleni kwasolwandle, ushizi kanye neminye imikhiqizo lapho kudingeka khona ukuvezwa komoya-mpilo okuncishisiwe.

Ukukhetha ifilimu ye-vacuum kufanele kucabangele ukumelana nokubhoboza, amandla okuvala, ukumelana nokugoba, ukuma kwephakeji kanye nesithiyo somoya-mpilo. Imikhiqizo enamathambo abukhali, amagobolondo noma imiphetho ingadinga izakhiwo ezihlukile zemishini ekudleni okuthambile okungenamathambo.

Ifilimu PET/PE Inyama Yokupakisha Inyama

Inyama entsha necutshunguliwe ingadinga ukuvikelwa ekudlulisweni komoya-mpilo, ukulahleka komswakama kanye nokuvuza kwephakeji ngenkathi ifuna futhi izivalo eziqinile kanye nokumelana nokucindezeleka kokuphatha.

Uma ukhetha ifilimu lokupakisha inyama, nikeza uhlobo lwenyama, isimo sayo sokuba nethambo noma ukungabi namathambo, inqubo ye-vacuum noma MAP , izinga lokushisa lokugcina kanye nesikhathi sokuphila kweshelufu eliqondiwe.

Ifilimu Evimbelayo Ephakeme Yezinhlanzi Nokudla Kwasolwandle

Izinhlanzi nezinhlanzi zasolwandle zifakiwe phakathi kwezicelo ezijwayelekile zokupakisha okuguquguqukayo okunezithiyo eziphakeme. Okuqukethwe kwe-HSQY yokuqala kufaka nesithombe sokufaka i-salmon.

Izidingo zokupakisha ukudla kwasolwandle zingahluka kakhulu phakathi kwe-salmon ebandayo entsha, inhlanzi eqandisiwe, i-shellfish kanye nokudla kwasolwandle okucutshunguliwe. Ngakho-ke isakhiwo sefilimu kufanele sihambisane nomkhiqizo wangempela, ifomethi yephakheji kanye nezimo zokushisa.

Ifilimu Evimbelayo Ephakeme Yoshizi Nobisi

Ushizi nemikhiqizo yobisi kungadinga ukudluliswa komoya-mpilo nomswakama okulawulwayo kanye nokuvalwa okuthembekile kanye nokumelana namafutha namafutha avela kumkhiqizo opakishiwe.

Ushizi ohlukene nawo unezidingo ezahlukene zokuphefumula kanye negesi, ngakho-ke ukudluliselwa kwegesi okuphansi kakhulu akulona iqiniso ngokuzenzakalelayo kuzo zonke izinhlobo zokusetshenziswa kobisi. Abathengi kufanele banikeze umkhiqizo kanye nomgomo wokuphila isikhathi eside.
