Izakhiwo ezisebenzayo zokupakisha izinto zefilimu ziqhuba ngqo ukuthuthukiswa kokusebenza kwezinto ezihlanganisiwe eziguquguqukayo zokupakisha. Okulandelayo isingeniso esifushane sezakhiwo zokusebenza zezinto zokupakisha ezimbalwa ezivame ukusetshenziswa.
1. Izinto zokupakisha ezivame ukusetshenziswa: ifilimu ye-PE
Izinto ze-PE ezivaleka ngokushisa zishintshile zisuka kumafilimu anongqimba olulodwa kuya kumafilimu anezingqimba eziningi e-extruded, ukuze amafomula wezendlalelo zangaphakathi, eziphakathi nangaphandle zingaklanywa ngendlela ehlukile. Idizayini yefomula ehlanganisiwe yezinhlobo ezahlukene zezinhlayiya ze-polyethylene zingakhiqiza amazinga okushisa ahlukene okuvalwa, amazinga okushisa ahlukene okuvalwa kokushisa, izakhiwo ezihlukene zokunqanda ukuvala uphawu,hamandla okunamathela, imiphumela elwa ne-static, njll., ukuze kuhlangatshezwane nezidingo ezithile zokupakishwa komkhiqizo kanye nezinto zefilimu ze-PE ezinezakhiwo ezihlukile zokusebenza.
Eminyakeni yamuva nje, amafilimu e-polyethylene (BOPE) ane-biaxially oriented oriented polyethylene (BOPE) nawo athuthukisiwe, athuthukisa amandla aqinile amafilimu e-polyethylene futhi abe namandla aphezulu okuvala ukushisa.
2. CPP Film Material
Izinto ze-CPP zivame ukusetshenziswa ku-BOPP / CPP lesi sakhiwo sokupakisha ukukhanya komswakama-umswakama, kodwa ukwakheka okuhlukile kwe-CPP resin kungenziwa futhi ngezici ezihlukene zokusebenza zefilimu, njengokuthuthukiswa kokumelana nezinga lokushisa eliphansi, ukumelana nokupheka okuphezulu, okuphansi. izinga lokushisa lokuvala, amandla aphezulu okubhoboza, ukumelana nokugqwala, nezinye izici zokusebenza zezinto zokuvala ukushisa.
Reminyakeni yamuva, imboni iphinde yasungula ifilimu ye-matte ye-CPP, ikhulisa umphumela wokuboniswa kwezikhwama zefilimu ze-CPP zongqimba olulodwa.
3. Izinto zefilimu ye-BOPP
Ifilimu ehlanganisiwe yokupakishwa okukhanyayo isetshenziswa kakhulu ifilimu yokukhanya ye-BOPP ejwayelekile nefilimu ye-matte ye-BOPP, kukhona nefilimu yokuvala ukushisa kwe-BOPP (ukuvalwa kokushisa okuhlangothini olulodwa noma okukabili), ifilimu yeparele ye-BOPP.
I-BOPP ibonakala ngamandla aqinile aqinile (afanele ukuphrinta okunemibala eminingi), izakhiwo ezinhle kakhulu zokuvimbela umhwamuko wamanzi, ezisetshenziswa kakhulu ekufakweni kokukhanya okumelana nomswakama ebusweni bezinto eziphrintiwe.
Ifilimu ye-BOPP ye-matte enomphumela wokuhlobisa we-matte ofana nephepha. Ifilimu yokuvala ukushisa kwe-BOPP ingasetshenziswa njengento yokupakisha enesendlalelo esisodwa, njengokusonga iphakethe langaphakathi likaswidi. Ifilimu ye-pearl ye-BOPP isetshenziswa kakhulu ekufakweni kwe-ayisikhilimu okokufaka ungqimba lokushisa okufakwa uphawu, ingagcina ukuphrinta kukayinki omhlophe, ukuminyana kwayo okuphansi, amandla okuvala angu-2 kuya ku-3N/15mm ukuze isikhwama sivuleke kalula ukuze sikhiphe okuqukethwe.
Ngaphezu kwalokho, njengefilimu ye-BOPP elwa nenkungu, ifilimu ye-laser ye-holographic OPP, iphepha lokwenziwa le-PP, ifilimu ye-BOPP ebolile kanye nolunye uchungechunge lwe-BOPP lwamafilimu asebenzayo nakho kuye kwaduma futhi kwasetshenziswa ebangeni elithile.
4. Izinto zokupakisha ezisetshenziswa kakhulu: Izinto zefilimu ye-PET
Ifilimu elikhanyayo le-12MICRONS PET elivamile lisetshenziswa kakhulu ekufakweni okuhlanganisiwe okuguquguqukayo, amandla okusebenza emikhiqizo yawo yokupakisha ene-laminated aphakeme kakhulu kunemikhiqizo eyinhlanganisela ye-BOPP enezingqimba ezimbili (iphansi kancane kunemikhiqizo eyinhlanganisela ye-BOPA enezingqimba ezimbili), kanye namandla okuvimbela umoya-mpilo. yefilimu eyinhlanganisela ye-BOPP/PE (CPP) ukunciphisa izikhathi ezingama-20 kuye kwezingama-30.
Ukumelana nokushisa kwezinto ze-PET kuhle kakhulu, futhi kungenziwa ku-flatness yezikhwama ezinhle. ifilimu ye-PET encipha ukushisa, ifilimu ye-matte PET PET encipha ukushisa, ifilimu ye-matte PET, ifilimu ye-polyester ephezulu, ifilimu ye-PET twist, ifilimu ye-PET yezinyembezi kanye neminye imikhiqizo esebenzayo nayo iyasetshenziswa.
5. Izinto ezijwayelekile zokupakisha : ifilimu yenayiloni
Ifilimu yenayiloni egxile ku-Biaxially isetshenziswa kakhulu ku-vacuum, izikhwama ezibilayo nezishisayo ngenxa yamandla ayo aphezulu, ukumelana nokubhoboza okuphezulu, ukumelana nezinga lokushisa okuphezulu kanye nokuvimbela umoya-mpilo okungcono.
Iningi lamaphakethe ane-laminated umthamo omkhulu angaphezu kuka-1.7kg aphinde asebenzise isakhiwo se-BOPA//PE sokumelana kahle nokuwa.
Ifilimu enayiloni ye-Cast, esetshenziswa kabanzi e-Japan ekufakweni kokudla okufriziwe, enokumelana okuhle kwezinga lokushisa eliphansi, ehlisa izinga lokuphuka kwesikhwama ngesikhathi sokugcinwa kwezinga lokushisa eliphansi kanye nokuhamba.
6. I-Common Packaging Material : I-Aluminium enamathela Ifilimu Yensimbi
I-vacuum aluminizing ikwifilimu (efana ne-PET, BOPP, CPP, PE, PVC, njll.) ebusweni bokwakheka kongqimba lwe-aluminium elicinene, ngaleyo ndlela ikhulise kakhulu ifilimu kumoya wamanzi, umoya-mpilo, umthamo wokuvimbela ukukhanya. , esetshenziswa kabanzi ekuhlanganisweni okuguquguqukayo kwe-VMPET, izinto ze-VMCPP.
I-VMPET ye-laminating yezendlalelo ezintathu, i-VMCPP ye-laminating enezingqimba ezimbili.
Isakhiwo se-OPP//VMPET//PE manje sesisetshenziswe ngokuvuthwa emifino yokunyathelisa, sihluma imikhiqizo kuphakheji ebilayo ye-vacuum. Isakhiwo se-PE manje sesisetshenziswe ngokuvuthwa ukukhama imifino, imikhiqizo ehluma ku-vacuum abilayo emaphaketheni, ukuze kunqotshwe ukushiyeka kwemikhiqizo ejwayelekile ye-aluminium, ungqimba lwe-aluminium kulula ukufuduka, ungamelani nokushiyeka kokubilisa, ukuthuthukiswa kwemikhiqizo ye-VMPET nge uhlobo olungaphansi, ngaphambi nangemva kokubilisa kwamandla okuxebuka angaphezu kuka-1.5N/15mm, futhi ungqimba lwe-aluminium alubonakali lufuduka, luthuthukise ukusebenza komgoqo jikelele wesikhwama.
7. Izinto ezivamile zokupakisha: I-aluminium foil
Ucwecwe lwe-aluminium lokupakishwa okuguquguqukayo ngokuvamile luyi-6.5μm noma 9μugqinsi lwe-m 12microns, i-aluminium foil ngokusobala iyisivimbelo esisezingeni eliphakeme, ukungena kwamanzi, ukungena komoyampilo, ukukhanya okungenasici kungu- "0", kodwa empeleni kunezimbobo kucwecwe lwe-aluminium kanye nokugoqeka okungekuhle kwephinifa, kunenqwaba yokupakishwa kwesithiyo sangempela. umphumela awulungile. Isihluthulelo sokusetshenziswa kwe-aluminium foil ukugwema izimbobo zokukhonkwane ngesikhathi sokucubungula, ukupakishwa nokuthutha, ngaleyo ndlela kuncishiswe umthamo wangempela wokuvinjelwa. Eminyakeni yamuva nje, kunokuthambekela kokuthi izinto ze-aluminium foil zithathelwe indawo izinto zokupakisha ezongayo ezindaweni ezisetshenziswa kuzo zendabuko.
8. Izinto zokupakisha ezisetshenziswa kakhulu: amafilimu anezithiyo ezimboziwe
Ikakhulukazi ifilimu ehlanganiswe nge-PVDC (ifilimu yokuhlanganisa i-K), ifilimu ehlanganiswe ne-PVA (Ifilimu enamathelayo).
I-PVDC inomgoqo we-oxygen omuhle kakhulu nokumelana nomswakama, futhi inokucaca okuhle kakhulu, ifilimu ye-PVDC embozwe esetshenziswa kwifilimu eyisisekelo ikakhulukazi i-BOPP, BOPET, BOPA, CPP, njll., kodwa futhi ingaba yi-PE, PVC, cellophane namanye amafilimu, ukupakishwa okuhlanganisiwe okuguquguqukayo kufilimu esetshenziswa kakhulu ye-KOPP, KPET, KPA.
9. Izinto Zokupakisha Ezivamile: Amafilimu Aphezulu Ahlanganisiwe Akhishwe Ngokuhlanganyela
I-co-extrusion iyipulasitiki emibili noma ngaphezulu ehlukene, ngokusebenzisa ama-extruder amabili noma ngaphezulu, ngokulandelana, ukuze izinhlobonhlobo zepulasitiki ezincibilika futhi zenziwe nge-plasticizing for pair of die head, ukulungiswa kwamafilimu ahlanganisiwe wendlela yokubumba. Amafilimu ayinhlanganisela ye-co-extruded barrier avame ukwenziwa ngenhlanganisela yamapulasitiki okuvimbela, amapulasitiki e-polyolefin nama-resin anamathelayo ezinhlobo ezintathu ezinkulu zezinto, ama-barrier resins ikakhulukazi i-PA, EVOH, PVDC, njll.
Okungenhla kuyizinto ezivamile zokupakisha kuphela, empeleni, okungenani ukusetshenziswa kwe-oxide vapor coating, i-PVC, i-PS, i-PEN, iphepha, njll. izici ezisebenzayo zezinto zefilimu. Ukufakwa kwamafilimu ahlukahlukene asebenzayo, ngokusebenzisa i-lamination eyomile, i-solvent-free lamination, i-extrusion lamination kanye nobunye ubuchwepheshe obuhlanganisiwe ukukhiqiza izinto zokupakisha eziguquguqukayo ezisebenzayo ukuhlangabezana nezidingo ezahlukene.imikhiqizoukupakisha.
