Ifilimu ye-OPP iwuhlobo lwefilimu ye-polypropylene, ebizwa ngefilimu ye-polypropylene e-co-extruded oriented (OPP) ngoba inqubo yokukhiqiza iyi-multi-layer extrusion. Uma kunenqubo yokwelula e-bi-directional ekucubungulweni, ibizwa ngokuthi ifilimu ye-polypropylene e-bi-directional oriented oriented (BOPP). Enye ibizwa nge-cast polypropylene film (CPP) ngokuphambene nenqubo ye-co-extrusion. Amafilimu amathathu ahlukene ngezakhiwo zawo kanye nokusetshenziswa kwawo.
I. Ukusetshenziswa okuyinhloko kwefilimu ye-OPP
I-OPP: I-polypropylene (ifilimu) eqondile, i-polypropylene eqondiswe, iwuhlobo olulodwa lwe-polypropylene.
Imikhiqizo emikhulu eyenziwe nge-OPP:
1, i-OPP tape: ifilimu ye-polypropylene njenge-substrate, enamandla amakhulu okudonsa, engasindi, ayinabuthi, ayinambitheki, inobungani bemvelo, ukusetshenziswa okubanzi nezinye izinzuzo
2, amalebula e-OPP:ngoba imakethe iyimikhiqizo yansuku zonke egcwele futhi i-homogenized, ukubukeka yikho konke, umbono wokuqala unquma ukuziphatha kokuthenga komthengi. I-shampoo, ijeli yokugeza, okokuhlanza neminye imikhiqizo isetshenziswa ezindlini zangasese ezifudumele nezinomswakama kanye namakhishi, izidingo zelebula ukumelana nomswakama futhi zingawi, futhi ukumelana kwayo nokukhishwa kufanele kuhambisane nebhodlela, kuyilapho amabhodlela asobala ukucaca kwezinto zokunamathisela kanye nokulebula kubeka phambili izidingo ezinzima.
Amalebula e-OPP ahlobene namalebula ephepha, anokucaca, amandla aphezulu, umswakama, akulula ukuwa kanye nezinye izinzuzo, nakuba izindleko zikhuphuka, kodwa zingathola isibonisi selebula elihle kakhulu nomthelela wokusebenzisa. Kodwa angathola isibonisi selebula esihle kakhulu futhi asebenzise umphumela. Ngokuthuthukiswa kobuchwepheshe bokunyathelisa basekhaya, ubuchwepheshe bokumboza, ukukhiqizwa kwamalebula efilimu azinamathelayo kanye namalebula amafilimu okuphrinta akuseyona inkinga, kungabikezelwa ukuthi ukusetshenziswa kwasekhaya kwamalebula e-OPP kuzoqhubeka nokwanda.
Njengoba ilebula ngokwayo iyi-PP, ingahlanganiswa kahle ne-PP/PE yesitsha sesitsha, umkhuba ufakazele ukuthi ifilimu ye-OPP njengamanje iyimpahla engcono kakhulu yokulebula okusesikhunjeni, imboni yokudla kanye nemboni yamakhemikhali yansuku zonke eYurophu kube yinani elikhulu lezicelo, futhi kancane kancane yasakazekela kwasekhaya, kukhona abasebenzisi abaningi ngokwengeziwe abaqala ukunaka noma ukusebenzisa inqubo yokulebula ekwisikhunta.
Okwesibili, inhloso eyinhloko yefilimu ye-BOPP
I-BOPP: Ifilimu ye-polypropylene egxile ku-Biaxially, kanye nohlobo olulodwa lwe-polypropylene.
Amafilimu e-BOPP asetshenziswa kakhulu afaka:
● ifilimu ye-polypropylene evamile ene-bi-oriented,
● ifilimu ye-polypropylene ene-heat-oriented bi-oriented,
● ifilimu yokupakisha kagwayi,
● ifilimu ye-polypropylene pearlescent ene-bi-oriented,
● ifilimu enensimbi ene-bi-oriented polypropylene,
● ifilimu ye-matte nokunye.
Ukusetshenziswa okuyinhloko kwamafilimu ahlukahlukene kungokulandelayo:
1, Ifilimu ye-BOPP evamile
Ikakhulu isetshenziselwa ukuphrinta, ukwenza izikhwama, njenge-adhesive tape kanye nenhlanganisela namanye ama-substrates.
2, ifilimu yokuvalwa kwe-BOPP yokushisa
Ikakhulu isetshenziselwa ukuphrinta, ukwenza izikhwama nokunye.
3, ifilimu yokupakisha kagwayi ye-BOPP
Sebenzisa: Isetshenziselwa ukupakisha ugwayi onesivinini esikhulu.
4, BOPP pearized ifilimu
Isetshenziselwa ukudla kanye nokupakishwa komkhiqizo wasendlini ngemva kokuphrinta.
5, Ifilimu ye-BOPP eyenziwe ngensimbi
Isetshenziswa njenge-vacuum metallization, imisebe, i-anti-counterfeiting substrate, ukupakishwa kokudla.
6, BOPP matte ifilimu
Isetshenziselwa insipho, ukudla, ugwayi, izimonyo, imikhiqizo yezemithi namanye amabhokisi okupakisha.
7, ifilimu ye-BOPP yokulwa nenkungu
Isetshenziselwa ukupakisha imifino, izithelo, i-sushi, izimbali nokunye.
Ifilimu ye-BOPP iyinto ebaluleke kakhulu yokupakisha eguquguqukayo, esetshenziswa kabanzi.
Ifilimu ye-BOPP ayinambala, ayinaphunga, ayinambitheki, ayinabo ubuthi, futhi inamandla aqinile aqinile, amandla omthelela, ukuqina, ukuqina kanye nokungafihli lutho okuhle.
Amandla efilimu ye-BOPP aphansi, iglue noma ayaphrinta ngaphambi kokwelashwa kwe-corona. Kodwa-ke, ifilimu ye-BOPP ngemuva kokwelashwa kwe-corona, inokuvumelana nezimo ezinhle zokuphrinta, ingaba ukuphrinta kombala futhi ithole ukubukeka okuhle, ngakho-ke ivame ukusetshenziswa njengefilimu eyinhlanganisela yezinto ezibonakalayo.
Ifilimu ye-BOPP nayo inokushiyeka, njengokulula ukuqongelela ugesi omile, akukho ukuvalwa kokushisa nokunye. Emgqeni wokukhiqiza wesivinini esikhulu, ifilimu ye-BOPP ithambekele kugesi omile, idinga ukufaka isikhiphi sikagesi esimile.
Ukuze uthole ifilimu ye-BOPP evaleka ukushisa, ukwelashwa kwe-corona yefilimu ye-BOPP kungambozwa nge-resin enamathelayo evaleka ukushisa, njenge-PVDC latex, i-EVA latex, njll. -extrusion laminating indlela ingasetshenziswa ukukhiqiza ukushisa-sealable BOPP ifilimu. Le filimu isetshenziswa kakhulu ekufakweni kwesinkwa, izingubo, izicathulo namasokisi, kanye nogwayi, ukupakishwa kwekhava yezincwadi.
Ukuqaliswa kwefilimu ye-BOPP yamandla ezinyembezi ngemva kokwelula kuye kwanda, kodwa amandla esibili izinyembezi aphansi kakhulu, ngakho-ke ifilimu ye-BOPP ayikwazi ukushiywa ezinhlangothini zombili zobuso bokuphela kwenotshi, ngaphandle kwalokho ifilimu ye-BOPP kulula ukuyidabula ekuphrinteni. , laminating.
I-BOPP ehlanganiswe ngetheyiphu yokuzinamathisela ingakhiqizwa ukuvala itheyiphu yebhokisi, umthamo we-BOPP ohlanganiswe ne-BOPP ozinamathelayo ungakhiqiza itheyiphu yokuvala, iwukusetshenziswa kwe-BOPP kwemakethe enkulu.
Amafilimu e-BOPP angakhiqizwa ngendlela yefilimu yeshubhu noma indlela yefilimu eyisicaba. Izakhiwo zamafilimu e-BOPP atholwe ngezindlela ezihlukene zokucubungula zihlukile. Ifilimu ye-BOPP ekhiqizwa indlela yefilimu eyisicaba ngenxa yesilinganiso esikhulu se-tensile (kufika ku-8-10), ngakho amandla aphezulu kunendlela yefilimu ye-tube, ukufana kwefilimu nakho kungcono.
Ukuze uthole ukusebenza okungcono okuphelele, ekusetshenzisweni kwenqubo kuvame ukusetshenziswa ekukhiqizeni indlela yokuhlanganiswa kwezingqimba eziningi.I-BOPP ingahlanganiswa nezinto ezihlukahlukene ezihlukahlukene ukuze kuhlangatshezwane nezidingo zezicelo ezikhethekile. Okufana ne-BOPP kungenziwa kuhlanganiswe ne-LDPE (CPP), i-PE, i-PT, i-PO, i-PVA, njll. amafilimu angasetshenziswa ekudleni okunamafutha.
Okwesithathu, inhloso eyinhloko yefilimu ye-CPP
I-CPP: ukukhanya okuhle, isicwebezelisi esiphezulu, ukuqina okuhle, umgoqo omuhle womswakama, ukumelana nokushisa okuhle kakhulu, ukufakwa uphawu kalula kokushisa nokunye.
Ifilimu ye-CPP ngemva kokunyathelisa, ukwenza izikhwama, ifanele: izingubo zokugqoka, izingubo zokuluka kanye nezikhwama zezimbali; imibhalo nama-albhamu ifilimu; ukupakisha ukudla; kanye nokupakishwa kwesithiyo kanye nefilimu yokuhlobisa eyenziwe ngensimbi.
Ukusetshenziswa okungase kube khona kuhlanganisa: ukumbozwa kokudla, i-confectionery overwrap (ifilimu elisontiwe), ukupakishwa kwemithi (izikhwama ezifakwayo), ukufaka esikhundleni se-PVC kuma-albhamu ezithombe, amafolda kanye nemibhalo, iphepha lokwenziwa, amateyipu azinamathiselayo, abanikazi bamakhadi ebhizinisi, izibophezelo zamasongo kanye nokuma. izinhlanganisela zesikhwama.
I-CPP inokumelana nokushisa okuhle kakhulu.
Njengoba indawo yokuthambisa ye-PP ingaba ngu-140 ° C, lolu hlobo lwefilimu lungasetshenziswa ezindaweni ezifana nokugcwalisa okushisayo, izikhwama ezishisayo kanye nokupakisha kwe-aseptic.
Ihlanganiswe ne-asidi enhle kakhulu, i-alkali kanye nokumelana namafutha, iyenza ibe yinto ekhethwayo ezindaweni ezifana nokupakishwa komkhiqizo wesinkwa noma izinto ezilamiwe.
Ukuphepha kokuxhumana nokudla kwayo, ukusebenza kwesethulo esihle kakhulu, ngeke kuthinte ukunambitheka kokudla ngaphakathi, futhi ingakhetha amamaki ahlukene e-resin ukuthola izici ezidingekayo.
