Amafilimu Ahlanganisiwe Anezithiyo Eziphakeme

Ayini Amafilimu Ahlanganisiwe Anezithiyo Eziphakeme?

Amafilimu ahlanganisiwe anezithiyo eziphakeme angamafilimu ahlanganiswe ngezingqimba eziningi aklanyelwe ukuvikela okuqukethwe okupakishwe emoyeni, umswakama, iphunga, ukukhanya, nezinye izinto zangaphandle.
Lawa mafilimu avame ukuhlanganisa izinto ezifana ne-PET, i-Nylon, i-EVOH, i-Aluminium foil, kanye ne-PE/CPP ukuze kufezwe ukusebenza okuhle kakhulu kwezithiyo.
Asetshenziswa kabanzi ekudleni, emithini, kanye nasekupakisheni kwezimboni okudinga isikhathi eside sokugcinwa kanye nobuqotho bomkhiqizo.

Yiziphi izinto ezivame ukusetshenziswa kumafilimu anezivikelo eziphakeme?

Izakhiwo zezinto ezivamile zifaka:
• I-PET/AL/PE (ifilimu ehlanganisiwe ye-aluminium foil)
• I-PET/NY/PE
• I-BOPP/EVOH/CPP
• Inayiloni/PE enesendlalelo esiyinhloko se-EVOH
• Ifilimu ehlanganisiwe ye-PET noma ye-BOPP eyenziwe ngensimbi
Lezi zinhlanganisela ezinezingqimba eziningi ziqinisekisa ukumelana okuhle kakhulu kwe-oxygen kanye nomswakama ngenkathi kugcinwa ukuguquguquka nokuqina.

Yiziphi izinzuzo eziyinhloko zokusebenzisa amafilimu ahlanganisiwe anezithiyo eziphakeme?

Amafilimu anezivikelo eziphakeme anikeza izinzuzo ezilandelayo:
• Izakhiwo ezivelele zokuvimbela umoya-mpilo kanye nomswakama
• Isikhathi eside sokuphila komkhiqizo eshalofini kanye nokugcinwa kokusha
• Iphunga elihle kakhulu, ukunambitheka, kanye nokuvikelwa kwe-UV
• Kufanelekela ukupakisha nge-vacuum kanye nokupakisha umoya okuguquliwe (i-MAP)
• Izindawo eziphrintwayo zokufaka uphawu kanye nokulebula
• Amandla aqinile omshini kanye nokumelana nokubhoboza

Yiziphi izinhlelo zokusebenza ezidinga amafilimu anezivikelo eziphakeme?

Amafilimu ahlanganisiwe anezivikelo eziphakeme asetshenziswa kabanzi ku:
• Inyama efakwe i-vacuum, amasoseji, kanye nokudla kwasolwandle
• Ikhofi, itiye, kanye nokupakisha ukudla okulula
• Imithi kanye namadivayisi ezokwelapha
• Ukupakisha ushizi, ubisi, kanye nokudla okuphuzwayo
• Ukudla kwezilwane ezifuywayo kanye nezithako zokudla
• Izingxenye ze-elekthronikhi kanye nezimboni ezizwela umswakama

Amafilimu anezithiyo eziphakeme aqhathaniswa kanjani namafilimu ajwayelekile?

Amafilimu ajwayelekile ahlanganisiwe anganikeza isivikelo esiyisisekelo kodwa awafaneleki emikhiqizweni edinga ukulondolozwa isikhathi eside.
Amafilimu anezivikelo eziphakeme afaka izendlalelo ezikhethekile njenge-aluminium foil, i-EVOH, noma i-PET eyenziwe ngensimbi ukuze kuncishiswe kakhulu amazinga okudlulisa igesi nomswakama (i-OTR ne-MVTR).
Aqinisekisa ukuvikelwa okungcono komkhiqizo, ikakhulukazi ezimweni zokugcina noma zokuthutha ezinzima.

Ingabe amafilimu anezivikelo eziphakeme afanelekile ekupakisheni nge-vacuum kanye ne-MAP?

Yebo, amafilimu ahlanganisiwe anezivikelo eziphakeme avame ukusetshenziswa ezikhwameni ze-vacuum kanye nasekupakishweni komoya okuguquliwe (i-MAP).
Ukungena kwawo okuphansi kusiza ukususa umoya-mpilo nokugcina i-nitrogen noma i-CO₂, okwandisa ubusha nokuvimbela ukukhula kwamagciwane.
Asetshenziswa kabanzi ekucubungulweni kwenyama, ekupakishweni koshizi, kanye nasekusetshenzisweni kokudla okulungele ukudliwa.

Ingabe amafilimu anezivikelo eziphakeme angavalwa, aphrintiwe, noma enziwe ngokwezifiso?

Impela. Lawa mafilimu angavalwa ngokushisa noma avalwe ngokubandayo, kuye ngesendlalelo sokuvala (PE, CPP, EVA, njll.).
Ahambisana nokugqwala, i-flexo, kanye nokuphrinta kwedijithali.
Izici ozikhethela zona zifaka phakathi ama-notches adabuka kalula, ama-zipper aphinde avalwe, i-anti-fog coating, kanye ne-laser scoring.
Ubukhulu, amazinga okuvimbela, kanye nokwelashwa kwendawo konke kungalungiswa ngokwezidingo ezithile zokupakisha.

Ingabe la mafilimu aphephile ekudleni futhi ahambisana nemithethonqubo?

Yebo, amafilimu ahlanganisiwe anezivikelo eziphakeme zokudla akhiqizwa ngokuhambisana nezindinganiso ze-FDA, EU, kanye ne-GB.
Aphephile ukuthintana ngqo nokudla neziphuzo, okuhlanganisa nezicelo eziqandisiwe, eziqandisiwe, kanye nezingasetshenziswa kabusha.
Izitifiketi zokuhlaziya (i-COA), imibiko yokuhlolwa kokufuduka, kanye namaphepha edatha yezinto ezibonakalayo kunganikezwa uma kuceliwe.

Yibuphi ubukhulu obutholakalayo kumafilimu anezivikelo eziphakeme?

Ubukhulu buvame ukusuka kuma-micron angu-50 kuya kuma-micron angu-180 kuye ngesakhiwo kanye nokusetshenziswa.
Amafilimu esikhwama se-vacuum ngokuvamile angama-micron angu-70-150, kuyilapho ama-laminate okudla okulula angaba mancane (ama-micron angu-20-60).
Izakhiwo ezenziwe ngokwezifiso zingaklanywa ngokusekelwe ekuzweleni komkhiqizo kanye nezidingo zokuphathwa kwemishini.

Ingabe amafilimu anezivikelo eziphakeme angaphinde asetshenziswe noma anobungani nemvelo?

Amafilimu ezithiyo zendabuko anezinto eziningi kunzima ukuwasebenzisa kabusha.
Kodwa-ke, amafilimu ezithiyo angasetshenziswa kabusha anezinto eziningi (isb., i-PE yonke noma i-PP yonke) atholakala kabanzi, enikeza izixazululo zokupakisha eziqhubekayo.
Abanye abakhiqizi banikeza namafilimu ezithiyo asekelwe ku-bio asebenzisa izinto ezifakwa kumquba njenge-PLA noma i-cellulose.
Kubalulekile ukufanisa izidingo zokusebenza nemigomo yokusimama ngesikhathi sokukhetha ifilimu.
