Ifilimu ye-OPP uhlobo lwefilimu ye-polypropylene, ebizwa ngokuthi ifilimu ye-co-extruded oriented polypropylene (OPP) ngoba inqubo yokukhiqiza iwukukhushulwa okunezingqimba eziningi. Uma kunenqubo yokwelula okunezingqimba ezimbili ekucutshungulweni, ibizwa ngokuthi ifilimu ye-polypropylene oriented bi-directional (BOPP). Enye ibizwa ngokuthi ifilimu ye-cast polypropylene (CPP) ngokungafani nenqubo ye-co-extrusion. Amafilimu amathathu ahlukile ngezakhiwo zawo kanye nokusetshenziswa kwawo.
I. Ukusetshenziswa okuyinhloko kwefilimu ye-OPP
I-OPP: i-polypropylene eqondiswe (ifilimu), i-polypropylene eqondiswe, uhlobo olulodwa lwe-polypropylene.
Imikhiqizo eyinhloko eyenziwe nge-OPP:
1, iteyipu ye-OPP: ifilimu ye-polypropylene njenge-substrate, enamandla aphezulu okubamba, alula, ayinabungozi, ayinambitheki, inobungani nemvelo, ububanzi bokusetshenziswa kanye nezinye izinzuzo
2, amalebula e-OPP:ngoba imakethe igcwele futhi ifana kakhulu nemikhiqizo yansuku zonke, ukubukeka kuyikho konke, umbono wokuqala unquma ukuziphatha komthengi kokuthenga. I-shampoo, i-shower gel, insipho neminye imikhiqizo isetshenziswa ezindlini zangasese ezifudumele nezinomswakama nasemakhishini, izidingo zelebula ukuze imelane nomswakama futhi ingawi, futhi ukumelana kwayo nokukhishwa kumele kuhambisane nebhodlela, kuyilapho amabhodlela abonakalayo ukuze kube sobala kwento yokunamathisela kanye nezinto zokulebula ebeka phambili izidingo ezinzima.
Amalebula e-OPP uma eqhathaniswa namalebula ephepha, ngokusobala, amandla aphezulu, umswakama, akulula ukuwa kanye nezinye izinzuzo, yize izindleko zikhuphuka, kodwa angathola isibonisi selebula esihle kakhulu kanye nomphumela wokusetshenziswa. Kodwa angathola isibonisi selebula esihle kakhulu kanye nomphumela wokusetshenziswa. Ngokuthuthuka kobuchwepheshe bokunyathelisa basekhaya, ubuchwepheshe bokumboza, ukukhiqizwa kwamalebula efilimu azinamathelayo kanye namalebula efilimu okunyathelisa akuseyona inkinga, kungabikezelwa ukuthi ukusetshenziswa kwamalebula e-OPP ekhaya kuzoqhubeka nokukhula.
Njengoba ilebula ngokwayo iyi-PP, ingahlanganiswa kahle ne-PP/PE container surface, umkhuba uye wafakazela ukuthi ifilimu ye-OPP okwamanje iyinto engcono kakhulu yokubhala ilebula ngaphakathi kwesikhunta, ukudla kanye nemboni yamakhemikhali yansuku zonke eYurophu kuye kwaba nenani elikhulu lezicelo, futhi kancane kancane yasakazeka yasekhaya, abasebenzisi abaningi baqala ukunaka noma ukusebenzisa inqubo yokubhala ilebula ngaphakathi kwesikhunta.
Okwesibili, inhloso eyinhloko yefilimu ye-BOPP
I-BOPP: Ifilimu ye-polypropylene eqondiswe ku-Biaxial, futhi uhlobo olulodwa lwe-polypropylene.
Amafilimu e-BOPP asetshenziswa kakhulu afaka:
● ifilimu ye-polypropylene ejwayelekile enama-bi-oriented,
● ifilimu ye-polypropylene eboshwe ngokushisa eboshwe kabili,
● ifilimu lokupakisha ugwayi,
● ifilimu ye-polypropylene pearlescent eqondiswe kabili,
● ifilimu yensimbi ye-polypropylene eqondiswe kabili,
● ifilimu engabonakali njalo njalo.
Ukusetshenziswa okuyinhloko kwamafilimu ahlukahlukene yilena elandelayo:
1, ifilimu evamile ye-BOPP
Isetshenziswa kakhulu ekuphrinteni, ekwenzeni izikhwama, njengetheyiphu yokunamathela kanye nokuhlanganiswa nezinye izinto ezisetshenziswayo.
2, ifilimu yokuvala ukushisa ye-BOPP
Isetshenziswa kakhulu ekuphrinteni, ekwenzeni izikhwama njalo njalo.
3, ifilimu yokufaka ugwayi we-BOPP
Ukusetshenziswa: Kusetshenziselwa ukupakisha ugwayi ngesivinini esikhulu.
4, ifilimu ye-BOPP enama-pearlized
Isetshenziselwa ukupakisha ukudla kanye nemikhiqizo yasekhaya ngemva kokuphrinta.
5, Ifilimu ye-BOPP Metallized
Isetshenziswa njenge-vacuum metallization, imisebe, i-substrate yokulwa nombumbulu, kanye nokupakishwa kokudla.
6, ifilimu ye-BOPP matte
Isetshenziselwa insipho, ukudla, ugwayi, izimonyo, imikhiqizo yemithi kanye namanye amabhokisi okupakisha.
7, ifilimu yokulwa nenkungu ye-BOPP
Isetshenziselwa ukupakisha imifino, izithelo, i-sushi, izimbali njalo njalo.
Ifilimu ye-BOPP iyinto ebaluleke kakhulu yokupakisha eguquguqukayo, esetshenziswa kabanzi.
Ifilimu ye-BOPP ayinambala, ayinaphunga, ayinambitheki, ayinabo ubuthi, futhi inamandla aphezulu okubamba, amandla okushaya, ukuqina, ukuqina kanye nokubonakala okuhle.
Amandla obuso befilimu ye-BOPP aphansi, anamathela noma anyatheliswe ngaphambi kokwelashwa kwe-corona. Kodwa-ke, ifilimu ye-BOPP ngemva kokwelashwa kwe-corona, iyakwazi ukunyathelisa kahle, inganyatheliswa ngombala futhi ibukeke kahle, ngakho-ke ivame ukusetshenziswa njengezinto zobuso befilimu ezihlanganisiwe.
Ifilimu ye-BOPP nayo inamaphutha, njengokuqoqa ugesi ozinzile kalula, akukho ukuvalwa kokushisa njalo njalo. Emugqeni wokukhiqiza osheshayo, ifilimu ye-BOPP ithambekele kugesi ozinzile, kudingeka kufakwe i-remover kagesi ozinzile.
Ukuze kutholakale ifilimu ye-BOPP evalwa ngokushisa, ukwelashwa kwe-corona yefilimu ye-BOPP ebusweni kungambozwa nge-resin adhesive evalwa ngokushisa, njenge-PVDC latex, i-EVA latex, njll., Kungambozwa nge-solvent adhesive, kodwa futhi indlela ye-extrusion coating noma i-co-extrusion laminating ingasetshenziswa ukukhiqiza ifilimu ye-BOPP evalwa ngokushisa. Le filimu isetshenziswa kabanzi ekupakisheni isinkwa, izingubo, izicathulo kanye namasokisi, kanye nokubhema, izincwadi ezimboziwe.
Ukuqala kwefilimu ye-BOPP kwamandla okudabuka ngemva kokunwebeka kukhuphukile, kodwa amandla okwesibili okudabuka aphansi kakhulu, ngakho ifilimu ye-BOPP ayikwazi ukushiywa ezinhlangothini zombili zobuso bokugcina be-notch, ngaphandle kwalokho ifilimu ye-BOPP kulula ukuyidabula ekunyatheliseni, i-laminating.
I-BOPP eboshwe ngetheyiphu yokuzinamathisela ingakhiqizwa ukuze ivale itheyiphu yebhokisi, uma umthamo we-BOPP we-BOPP oboshwe ngetheyiphu yokuzinamathisela ungakhiqiza itheyiphu yokuzinamathisela, ukusetshenziswa kwe-BOPP emakethe enkulu.
Amafilimu e-BOPP angakhiqizwa ngendlela yefilimu yeshubhu noma indlela yefilimu eyisicaba. Izakhiwo zamafilimu e-BOPP atholakala ngezindlela ezahlukene zokucubungula zihlukile. Ifilimu ye-BOPP ekhiqizwa ngendlela yefilimu eyisicaba ngenxa yesilinganiso esikhulu sokudonseka (kufika ku-8-10), ngakho-ke amandla aphezulu kunendlela yefilimu yeshubhu, ukufana kobukhulu befilimu nakho kungcono.
Ukuze kutholakale ukusebenza okungcono kakhulu, inqubo ivame ukusetshenziswa ekukhiqizweni kwendlela ehlanganisiwe enezingqimba eziningi. I-BOPP ingahlanganiswa nezinto ezahlukahlukene ukuze kuhlangatshezwane nezidingo zezicelo ezikhethekile. Njenge-BOPP ingahlanganiswa ne-LDPE (CPP), i-PE, i-PT, i-PO, i-PVA, njll. ukuze kutholakale izinga eliphezulu lokuvimba igesi, ukuvimbela umswakama, ukucaca, ukumelana nokushisa okuphezulu nokuphansi, ukumelana nokupheka kanye nokumelana namafutha, amafilimu ahlukahlukene ahlanganisiwe angasetshenziswa ekudleni okunamafutha.
Okwesithathu, inhloso eyinhloko yefilimu ye-CPP
I-CPP: ukucaca okuhle, ukucwebezela okuphezulu, ukuqina okuhle, isithiyo esihle somswakama, ukumelana nokushisa okuhle kakhulu, ukuvala okulula ukufudumeza njalo njalo.
Ifilimu ye-CPP ngemva kokuphrinta, ukwenza izikhwama, efanelekile: izikhwama zezingubo, izingubo ezithungiwe kanye nezimbali; amadokhumenti nama-albhamu ifilimu; ukupakishwa kokudla; kanye nokupakisha okuvimbelwe kanye nefilimu yokuhlobisa enensimbi.
Ukusetshenziswa okungenzeka kufaka phakathi: ukusonga ukudla, ukusonga amaswidi (ifilimu esontekile), ukupakishwa kwemithi (izikhwama zokufaka), ukufaka esikhundleni se-PVC kuma-albhamu ezithombe, amafolda namadokhumenti, iphepha lokwenziwa, amatheyiphu azinamathelayo, izibambi zamakhadi ebhizinisi, izihlanganisi zendandatho kanye nezinhlanganisela zezikhwama ezimile.
I-CPP inokumelana okuhle kakhulu nokushisa.
Njengoba iphuzu lokuthambisa le-PP lingaba ngu-140°C, lolu hlobo lwefilimu lungasetshenziswa ezindaweni ezifana nokugcwalisa okushisayo, izikhwama zomusi kanye nokupakisha okungenamagciwane.
Uma ihambisana nokumelana okuhle kakhulu ne-asidi, i-alkali kanye namafutha, iyenza ibe yinto ekhethwayo ezindaweni ezifana nokupakishwa kwemikhiqizo yesinkwa noma izinto ezifakwe i-laminate.
Ukuphepha kwayo ekuthinteni ukudla, ukusebenza kwayo okuhle kakhulu, ngeke kuthinte ukunambitheka kokudla okungaphakathi, futhi ingakhetha amazinga ahlukene e-resin ukuthola izici ezifiselekayo.
