Isingeniso sokuqonda umehluko phakathi kwefilimu ye-CPP, ifilimu ye-OPP, ifilimu ye-BOPP kanye nefilimu ye-MOPP

Indlela yokwahlulela i-opp,cpp,bopp,VMopp, sicela uhlole okulandelayo.

I-PP yigama le-polypropylene. Ngokwesakhiwo kanye nenhloso yokusetshenziswa, kwadalwa izinhlobo ezahlukene ze-PP.

I-CPP ifilimu iyifilimu ye-polypropylene ephothiwe, eyaziwa nangokuthi ifilimu ye-polypropylene enganwetshiwe, engahlukaniswa ibe yifilimu ye-general CPP (General CPP), ifilimu ye-metalize CPP (Metalize CPP, MCPP) kanye nefilimu ye-Retort CPP (Retort CPP, RCPP), njll.

Mi-ainFukudla

- Izindleko eziphansi kunezinye ifilimu ezifana ne-LLDPE, LDPE, HDPE, PET njll.

-Ukuqina okuphezulu kunefilimu ye-PE.

-Izakhiwo ezinhle kakhulu zokuvimbela umswakama kanye nephunga.

- Isebenza ngezindlela eziningi, ingasetshenziswa njengefilimu eyisisekelo ehlanganisiwe.

- I-Metallization Coating iyatholakala.

-Njengokupakisha ukudla nezimpahla kanye nokupakisha kwangaphandle, inesimo esihle kakhulu futhi ingenza umkhiqizo ubonakale ngokucacile ngephakheji.

Ukusetshenziswa kwefilimu ye-CPP

Ifilimu ye-Cpp ingasetshenziswa ezimakethe ezingezansi. Ngemva kokuphrinta noma ukubopha.

Izikhwama ezifakwe i-laminated ifilimu yangaphakathi
2. (Ifilimu eyenziwe nge-aluminium) Ifilimu eyenziwe ngensimbi yokupakisha nokuhlobisa izithiyo. Ngemva kokufaka i-vacuum aluminiyamu, ingahlanganiswa ne-BOPP, i-BOPA nezinye izinto ezisetshenziswayo zokupakisha itiye, ukudla okuthosiwe okuthosiwe, amabhisikidi, njll.
3. (Ifilimu egoqayo) i-CPP enokumelana okuhle kakhulu nokushisa. Njengoba iphuzu lokuthambisa le-PP lingaba ngu-140°C, lolu hlobo lwefilimu lungasetshenziswa ekugcwaliseni okushisayo, ezikhwameni ezigoqayo, ekupakisheni okungasetshenziselwe amagciwane nakwezinye izinkambu. Ngaphezu kwalokho, inokumelana okuhle kakhulu ne-asidi, ukumelana ne-alkali kanye nokumelana namafutha, okwenza ibe yisinqumo esingcono kakhulu sokupakisha umkhiqizo wesinkwa noma izinto ezifakwe i-laminate. Iphephile ekuthinteni ukudla, inokusebenza okuhle kakhulu kokwethula, igcina ukunambitheka kokudla ngaphakathi, futhi kunezinhlobo ezahlukene ze-resin ezinezimpawu ezahlukene.
4. (Ifilimu esebenzayo) Ukusetshenziswa okungenzeka kufaka phakathi: ukupakishwa kokudla, ukupakishwa kwamaswidi (ifilimu esontekile), ukupakishwa kwemithi (izikhwama zokufaka), ukufaka esikhundleni se-PVC kuma-albhamu ezithombe, amafolda namadokhumenti, iphepha lokwenziwa, i-Adhesive tape engomi, izibambi zamakhadi ebhizinisi, amafolda endandatho, kanye nezinhlanganisela zezikhwama ezime phezulu.
5. Izimakethe zezicelo ezintsha ze-CPP, njengokupakisha amabhokisi e-DVD kanye nokubukwayo okulalelwayo, ukupakisha i-bakery, ukupakisha amafilimu nezimbali zemifino nezithelo ezilwa nenkungu, kanye nephepha lokwenziwa lamalebula.

Ifilimu ye-OPP

I-OPP yi-Oriented Polypropylene.

Izici

Ifilimu ye-BOPP ibaluleke kakhulu njengezinto zokupakisha eziguquguqukayo. Ifilimu ye-BOPP icacile, ayinaphunga, ayinambitheki, ayinabo ubuthi, futhi inamandla aphezulu okubamba, amandla okushaya, ukuqina, ukuqina, kanye nokubonakala okuphezulu.

Ukwelashwa kwe-corona yefilimu ye-BOPP ebusweni kuyadingeka ngaphambi kokunamathisela noma ukuphrinta. Ngemva kokwelashwa kwe-corona, ifilimu ye-BOPP iyakwazi ukunyathelisa kahle, futhi inganyatheliswa ngombala ukuze ithole umphumela omuhle kakhulu, ngakho-ke ivame ukusetshenziswa njengendwangu yongqimba olungaphezulu lwefilimu ehlanganisiwe noma elaminethiwe.

Ukushoda:

Ifilimu ye-BOPP nayo inezinkinga, njengokulula ukuqoqa ugesi oqinile, ukungavali ukushisa, njll. Emgqeni wokukhiqiza wesivinini esikhulu, amafilimu e-BOPP athambekele kugesi oqinile, futhi kudingeka kufakwe ama-static eliminator. Ukuze kutholakale ifilimu ye-BOPP evala ukushisa, i-resin glue evala ukushisa, njenge-PVDC latex, i-EVA latex, njll., ingambozwa ebusweni befilimu ye-BOPP ngemuva kokwelashwa kwe-corona, i-solvent glue nayo ingambozwa, futhi i-extrusion coating noma i-coating nayo ingasetshenziswa. Indlela ehlanganisiwe ye-co-extrusion yokukhiqiza ifilimu ye-BOPP evala ukushisa.

Ukusetshenziswa

Ukuze kutholakale ukusebenza okungcono okuphelele, izindlela zokuhlanganiswa ezinezingqimba eziningi zivame ukusetshenziswa enqubweni yokukhiqiza. I-BOPP ingahlanganiswa nezinto eziningi ezahlukene ukuze kuhlangatshezwane nezidingo ezikhethekile zohlelo lokusebenza. Isibonelo, i-BOPP ingahlanganiswa ne-LDPE, i-CPP, i-PE, i-PT, i-PO, i-PVA, njll. ukuze kutholakale isithiyo segesi esiphezulu, isithiyo somswakama, ukucaca, izinga lokushisa eliphezulu kanye nokumelana nokushisa okuphansi, ukumelana nokupheka kanye nokumelana namafutha. Amafilimu ahlukene ahlanganisiwe angasetshenziswa ekudleni okunamafutha, ukudla okumnandi, ukudla okomile, ukudla okucwilisiwe, zonke izinhlobo zokudla okuphekiwe, ama-pancake, amakhekhe elayisi kanye nokunye ukupakisha.

 I-VMOPPIfilimu

I-VMOPP ifilimu ye-BOPP eyenziwe nge-aluminium, ungqimba oluncane lwe-aluminium olumbozwe ebusweni befilimu ye-BOPP ukuze ibe nokukhanya kwensimbi futhi ifinyelele umphumela okhanyayo. Izici ezithile yilezi ezilandelayo:

1. Ifilimu eyenziwe nge-aluminium inokukhanya okuhle kakhulu kwensimbi kanye nokukhanya okuhle, inikeza umuzwa wokunethezeka. Ukuyisebenzisa ukupakisha izimpahla kuthuthukisa umbono wemikhiqizo.
2. Ifilimu e-aluminium inezakhiwo ezinhle kakhulu zokuvimba igesi, izakhiwo zokuvimbela umswakama, izakhiwo zomthunzi kanye nezakhiwo zokugcina amakha. Ayigcini nje ngokuba nezakhiwo eziqinile zokuvimbela umoya-mpilo kanye nomhwamuko wamanzi, kodwa futhi ingavimba cishe yonke imisebe ye-ultraviolet, ukukhanya okubonakalayo kanye nemisebe ye-infrared, engakwazi ukwandisa impilo yeshelufu yokuqukethwe. Ngokudla, imithi kanye neminye imikhiqizo edinga ukwandisa impilo yeshelufu, kuyisinqumo esihle ukusebenzisa ifilimu e-aluminium njengokupakisha, okungavimbela ukudla noma okuqukethwe ukuthi kungonakaliswe ngenxa yokumuncwa komswakama, ukungena komoya-mpilo, ukuvezwa kokukhanya, i-metamorphism, njll. Ifilimu e-aluminium nayo enezakhiwo njengokugcina amakha, izinga lokudlulisa amakha liphansi, okungagcina iphunga lokuqukethwe isikhathi eside. Ngakho-ke, ifilimu e-aluminium iyinto enhle kakhulu yokupakisha amakha.
3. Ifilimu e-aluminium ingaphinde ithathe indawo ye-aluminium foil yezinhlobo eziningi zezikhwama zokupakisha ezivimbezelayo kanye nefilimu. Inani le-aluminium elisetshenziswayo lincishisiwe kakhulu, okungagcini nje ngokusindisa amandla nezinto zokwakha, kodwa futhi kunciphisa nezindleko zokupakisha izimpahla ngezinga elithile.
4. Ingqimba e-aluminium ebusweni be-VMOPP enomoya omuhle futhi ingaqeda ukusebenza kwe-electrostatic. Ngakho-ke, isici sokuvala sihle, ikakhulukazi lapho kufakwa izinto eziwumpuphu, singaqinisekisa ukuqina kwephakheji. Kunciphisa kakhulu ukuvela kwezinga lokuvuza.

Isakhiwo Sezinto Ezilahliwe Zezikhwama Zokupakisha ze-Pp Noma Ifilimu Elahliwe.
