Njengamanje, isithiyo esiphezulu namafilimu anemisebenzi eminingi athuthukela ezingeni elisha lobuchwepheshe. Ngokuqondene nefilimu esebenzayo, ngenxa yomsebenzi wayo okhethekile, ingakwazi ukuhlangabezana kangcono nezidingo zokupakishwa kwempahla, noma ihlangabezane kangcono nezidingo zokunethezeka kwempahla, ngakho umphumela uba ngcono futhi uqhudelane kakhulu emakethe. Lapha, sizogxila kumafilimu e-BOPP nawe-PET
I-BOPP, noma i-Biaxially Oriented Polypropylene, ifilimu yepulasitiki esetshenziswa kakhulu ekupakisheni nasekulebeni. Ingena kunqubo yokuma kwe-biaxial, ithuthukisa ukucaca kwayo, amandla, nokuphrinta. Yaziwa ngokuguquguquka kwayo, i-BOPP ivamise ukusetshenziswa ekufakweni okuguquguqukayo, amalebula, amateyipu okunamathiselayo, kanye nezinhlelo zokusebenza ze-lamination. Inikeza ukubonakala okuhle komkhiqizo, ukuqina, futhi iyakwazi ukugaywa kabusha, okuyenza ibe ukukhetha okudumile ngezidingo zokupakisha ezahlukahlukene.
I-PET, noma i-Polyethylene Terephthalate, i-thermoplastic polymer esetshenziswa kakhulu eyaziwa ngokuhlukahluka kwayo nokucaca kwayo. Ngokuvamile esetshenziswa ekukhiqizeni amabhodlela epulasitiki okuphuzwayo, iziqukathi zokudla, kanye nokupakishwa, i-PET ibonakala esobala futhi inezakhiwo ezinhle kakhulu zokuvimbela umoya-mpilo nomswakama. Ayisindi, iqinile, futhi iyasebenziseka kabusha, okuyenza ibe yinketho edumile ezinhlelweni zokupakisha ezahlukahlukene. Ukwengeza, i-PET isetshenziselwa imicu yezingubo, kanye nokukhiqizwa kwamafilimu namashidi ngezinjongo ezihlukahlukene.
Umehluko
I-PET imele i-polyethylene terephthalate, kuyilapho i-BOPP imele i-biaxially oriented polypropylene. Amafilimu e-PET kanye ne-BOPP angamafilimu amancane epulasitiki asetshenziswa kakhulu ukupakishwa. Kokubili ukukhetha okudumile kokupakishwa kokudla nezinye izinhlelo zokusebenza, njengamalebula omkhiqizo nokusonga okuvikelayo.
Mayelana nomehluko phakathi kwamafilimu e-PET ne-BOPP, umehluko osobala kakhulu yizindleko. Ifilimu ye-PET ijwayele ukubiza kakhulu kunefilimu ye-BOPP ngenxa yamandla ayo aphezulu kanye nezindawo zokuthibela. Nakuba ifilimu ye-BOPP ibiza kakhulu, ayihlinzeki ngesivikelo esifanayo noma izici zokuvimbela njengefilimu ye-PET.
Ngaphezu kwezindleko, kunomehluko wokumelana nezinga lokushisa phakathi kwezinhlobo ezimbili zefilimu. Ifilimu ye-PET inephuzu lokuncibilika eliphakeme kunefilimu ye-BOPP, ngakho-ke ingakwazi ukumelana namazinga okushisa aphakeme ngaphandle kokungqubuzana noma ukuncipha. Ifilimu ye-BOPP imelana kakhulu nomswakama, ngakho-ke ingavikela imikhiqizo ezwela umswakama.
Ngokuphathelene nezakhiwo zokubonwayo zamafilimu e-PET ne-BOPP, ifilimu ye-PET inokucaca okuphakeme nokucwebezela, kuyilapho ifilimu ye-BOPP inesiphetho se-matte. Ifilimu ye-PET iyisinqumo esingcono uma ufuna ifilimu enikeza izici ezinhle kakhulu zokubona.
Amafilimu e-PET kanye ne-BOPP enziwe ngama-resin epulasitiki kodwa aqukethe izinto ezihlukile. I-PET ihlanganisa i-polyethylene terephthalate, ehlanganisa ama-monomers amabili, i-ethylene glycol, ne-terephthalic acid. Le nhlanganisela idala into eqinile futhi engasindi imelana kakhulu nokushisa, amakhemikhali, nezincibilikisi. Ngakolunye uhlangothi, ifilimu ye-BOPP yenziwe nge-polypropylene e-biaxially-oriented, inhlanganisela ye-polypropylene nezinye izakhi zokwenziwa. Le nto futhi inamandla futhi ilula kodwa imelana kancane nokushisa namakhemikhali.
Lezi zinto ezimbili zinokufana okuningi mayelana nezakhiwo ezibonakalayo. Zombili zisobala kakhulu futhi zinokucaca okuhle kakhulu, okuzenza zilungele izinhlelo zokusebenza ezidinga ukubuka okucacile kokuqukethwe. Ukwengeza, zombili izinto zokwakha ziqinile futhi ziyavumelana nezimo, zizenza zilungele ukusetshenziswa okuhlukahlukene.
Nokho, kukhona umehluko oyinhloko. I-PET iqinile kunefilimu ye-BOPP futhi ayingenwa kalula ukudabuka noma ukubhoboza. I-PET inezinga eliphezulu lokuncibilika futhi imelana kakhulu nemisebe ye-UV. Ngakolunye uhlangothi, ifilimu ye-BOPP ithambile kakhulu futhi inganwetshwa futhi ilolongelwe ukuze ilingane nezinhlelo zokusebenza ezahlukahlukene.
isifinyezo
Sengiphetha, ifilimu yezilwane ezifuywayo nefilimu ye-Bopp inomehluko wayo. Ifilimu ye-PET ifilimu ye-polyethylene terephthalate, eyenza ibe i-thermoplastic engashiswa futhi ibunjwe ngaphandle kokulahlekelwa ubuqotho bayo besakhiwo. Inokuqina okuhle kakhulu kwe-dimensional, izakhiwo ze-optical, nokumelana namakhemikhali, okwenza kube ukukhetha okuhle ezinhlelweni eziningi. Ifilimu ye-Bopp, ngakolunye uhlangothi, ifilimu ye-polypropylene egxile ku-biaxially. Yimpahla engasindi kodwa eqinile enezinto ezinhle kakhulu zokubona, zokukhanda, nezishisayo. Kuwusizo ezinhlelweni zokusebenza lapho kudingeka khona ukucaca okuphezulu namandla aphakeme.
Lapho ukhetha phakathi kwalawa mafilimu amabili, kubalulekile ukucabangela isicelo. Ifilimu ye-PET ilungele izinhlelo zokusebenza ezidinga ukuzinza okukhulu kwe-dimensional kanye nokumelana namakhemikhali. Ifilimu ye-Bopp ifaneleka kakhulu ezinhlelweni ezidinga ukucaca okuphezulu namandla aphakeme.
Sithemba ukuthi le bhulogi isizile ukuthi uqonde kangcono umehluko phakathi kwamafilimu ezilwane ezifuywayo nawe-Bopp futhi ukhethe elifaneleka kangcono isicelo sakho.
