Ifilimu yokupakisha yenziwa ngokuyinhloko ngokuxuba nokukhipha izinhlaka ze-polyethylene eziningana zezinhlobo ezahlukene.Inokumelana nokubhoboza, amandla amakhulu nokusebenza okuphezulu.
Amafilimu okupakishazihlukaniswa zibe izigaba eziyisikhombisa: PVC, CPP, OPP, CPE, ONY, PET kanye AL.
1. I-PVC
Ingasetshenziselwa ukwenza ifilimu yokupakisha, ifilimu ye-PVC encipha ukushisa, njll. Isicelo: ilebula yebhodlela le-PVC.
2. Cast polypropylene ifilimu
Ifilimu ye-Cast polypropylene ifilimu ye-polypropylene ekhiqizwa inqubo yokusakazwa kwe-tape.Ingase futhi ihlukaniswe ibe yi-CPP evamile kanye ne-CPP yokupheka.Inokubonakala okuhle kakhulu, ukujiya okufanayo, nokusebenza okufanayo kuzo zombili izikhombisi-ndlela eziqondile nezivundlile.Ngokuvamile isetshenziswa njengendwangu yongqimba yangaphakathi yefilimu eyinhlanganisela.
I-CPP (i-Cast Polypropylene) ifilimu ye-polypropylene (PP) ekhiqizwa inqubo ye-cast extrusion embonini yepulasitiki.Isicelo: Isetshenziselwa ikakhulukazi ungqimba olungaphakathi lokuvala lweifilimu ehlanganisiwe, elungele ukupakishwa kwamafutha aqukethe izihloko kanye nokupakishwa okumelana nokupheka.
3. Ifilimu ye-polypropylene egxile ku-Biaxially
Ifilimu ye-polypropylene egxile ku-Biaxially yenziwa ngokukhipha izinhlayiya ze-polypropylene zibe amashidi, bese yelula kuzo zombili izikhombisi-ndlela eziqondile nezivundlile.
Isicelo: 1. Ikakhulu isetshenziselwaifilimu ehlanganisiweindawo yokunyathelisa.2. Ingenziwa ibe yifilimu ye-pearlescent (OPPD), ifilimu yokuqothula (OPPZ), njll. ngemva kokucubungula okukhethekile.
4. I-Chlorinated Polyethylene (CPE)
I-Chlorinated polyethylene (CPE) iyi-polymer egcwele enokubukeka kwempushana emhlophe, engenabuthi futhi ayinambitheki.Inokumelana nesimo sezulu esihle kakhulu, ukumelana ne-ozone, ukumelana namakhemikhali nokumelana nokuguga, kanye nokumelana kahle nowoyela, ukubambezeleka komlilo kanye nokusebenza kombala.
5. Ifilimu yenayiloni (ONY)
Ifilimu inayiloni ifilimu eqinile enokucaca okuhle, icwebezela kahle, amandla aqine kakhulu, amandla aqinile aphezulu, ukumelana nokushisa okuhle, ukumelana nokubanda, ukumelana nowoyela kanye nokumelana ne-organic solvent, ukumelana okuhle kokuhuzuka, ukumelana nokubhoboza, nokuthambile, ukumelana komoya-mpilo okuhle kakhulu; kodwa inomsebenzi ongemuhle wokuvimbela umhwamuko wamanzi, ukumuncwa komswakama ophezulu, ukungena komswakama, kulungele ukupakisha impahla eqinile, njengokudla okunamafutha Imikhiqizo yenyama, ukudla okuthosiwe, ukudla okupakishwe ngevacuum, ukudla okupheka njll.
Isicelo: 1. Isetshenziselwa ikakhulukazi ungqimba olungaphezulu kanye nongqimba oluphakathi lwe-membrane eyinhlanganisela.2. Ukupakisha ukudla kukawoyela, ukupakisha okufriziwe, ukupakishwa kwevacuum, ukupheka ukuvala inzalo.
6. Ifilimu ye-polyester (PET)
Ifilimu ye-polyester yenziwe nge-polyethylene terephthalate njengento eluhlaza, ekhishwa ibe amashidi aminyene bese yelulwa nge-biaxially.
Kodwa-ke, intengo yefilimu ye-polyester iphakeme kakhulu, enogqinsi olujwayelekile lwe-12mm.Ivame ukusetshenziswa njengempahla yangaphandle yokupheka emaphaketheni, futhi inokuphrinta okuhle.
Izicelo: 1. Izinto zokunyathelisa ezingaphezulu kwefilimu eyinhlanganisela;2. Kungenziwa aluminizeki.
7. AL (icwecwe le-aluminium)
I-aluminium foil iwuhlobo lwempahla yokupakishalokho akukashintshwa.Kuyi-conductor yokushisa enhle kakhulu kanye ne-sunshade.
8. Ifilimu ye-Aluminized
Njengamanje, amafilimu asetshenziswa kakhulu aluminized ikakhulukazi afaka ifilimu ye-polyester aluminized (VMPET) kanye nefilimu ye-CPP aluminized (VMCPP).Ifilimu eyenziwe nge-aluminium inezici zazo zombili ifilimu yepulasitiki nensimbi.Indima yokugqoka i-aluminium ebusweni befilimu ukuvimbela ukukhanya nokuvimbela imisebe ye-ultraviolet, engagcini nje ukwandisa impilo yeshalofu yokuqukethwe, kodwa futhi ithuthukisa ukukhanya kwefilimu.Ngokwezinga elithile, ithatha indawo ye-aluminium foil, futhi iphinde ibe nokusebenza kwesithiyo esishibhile, esihle futhi esihle.Ngakho-ke, ukumbozwa kwe-aluminium kusetshenziswa kakhulu emaphaketheni ayinhlanganisela, ikakhulukazi asetshenziswa emaphaketheni angaphandle okudla okomile nokukhukhumele njengamabhisikidi.
