Embonini yokupakisha nokunyathelisa, amafilimu epulasitiki asetshenziswa kabanzi ekudleni, kumakhemikhali ansuku zonke, emithini yemithi, nakweminye imikhakha ngenxa yezakhiwo zawo ezilula, ezihlala isikhathi eside, nezisebenziseka kalula. Phakathi kwamasu ahlukahlukene okunyathelisa, ukunyathelisa nge-flexographic sekuyindlela ekhethwayo yokunyathelisa amafilimu epulasitiki ngenxa yokusebenza kahle kwayo, ubungane bemvelo, kanye nokuzivumelanisa nezimo okunamandla. Kungakhathaliseki ukuthi kuphakejiwe ukudla okulula noma amalebula epulasitiki, ukunyathelisa nge-flexographic kuhlangabezana nezidingo zemakethe ngekhwalithi yokunyathelisa evelele kanye nokusebenza kahle kokukhiqiza okuzinzile.
Ukuphrinta amafilimu epulasitiki ngokuvamile kudinga ukukhiqizwa okusheshayo nokuqhubekayo, futhi indlela yokuphrinta ye-flexography yokugoqa-ukuya-ekugoqeni ihambisana kahle nalesi sidingo. Uma kuqhathaniswa nokuphrinta kwe-offset noma i-gravure, iphrinta ye-flexographic inesakhiwo esilula kanye nesivinini esisheshayo sokushintsha amapuleti, kunciphisa kakhulu ukuphazamiseka kokukhiqiza futhi kuthuthukisa ukusebenza kahle. Ikakhulukazi kuma-oda amakhulu njengokupakisha ukudla kanye nezikhwama zokuthenga, ukuphrinta kwe-flexographic kungagcina umkhiqizo ozinzile ngesivinini samamitha angamakhulu ngomzuzu ngenkathi kuqinisekiswa ukuvumelana kombala. Ngaphezu kwalokho, iphrinta ye-flexographic ibonisa ukuzivumelanisa okuhle kakhulu nezinto ezahlukahlukene zefilimu, kufaka phakathi i-polyethylene (PE), i-polypropylene (PP), i-polyester (PET), kanye namafilimu e-PLA abola, kufinyelela ukunamathela okuqinile kweyinki futhi kugweme izinkinga ezifana nokuxebuka noma ukuvimba.
Njengoba umhlaba ugcizelela kakhulu ukupakisha okusimeme, ubungane bemvelo bezinqubo zokuphrinta sebuyinto ebalulekile.FUmshini wokunyathelisa we-lexo usebenzisa uyinki osekelwe emanzini noma ongelapheka nge-UV, oqukethe amakhemikhali e-organic aguquguqukayo amancane noma angenawo nhlobo (ama-VOC), okunciphisa ukungcola kwemvelo nokunciphisa izinsalela ze-solvent ezintweni zokupakisha. Lokhu kuyenza ifaneleke kakhulu ezimbonini ezinezidingo zokuphepha eziqinile, njengokudla kanye nemithi.
Ngaphezu kwalokho, amapuleti omshini wokunyathelisa we-flexo ngokuvamile enziwa nge-resin ye-photopolymer eguquguqukayo, esebenzisa amandla amancane futhi ikhiqize imfucuza encane ngesikhathi sokwenza amapuleti uma kuqhathaniswa nokunyathelisa nge-gravure. Ngokuphambene nesizinda "sokungakhethi kwe-carbon" kanye "nemikhawulo yepulasitiki," ukunyathelisa kwe-flexo sekuyindlela ekhethwayo yemikhiqizo kanye nabakhiqizi bokupakisha, okusiza izinkampani ukufeza imigomo yokukhiqiza eluhlaza.
Nakuba ukuphrinta kwe-gravure kunikeza ukunemba okuphezulu kakhulu, izindleko zako zokwenza amapuleti ziphakeme, futhi inqubo ithatha isikhathi. Ngokuphambene nalokho, izixazululo zethu zokuphrinta ze-flex ziletha ikhwalithi yokuphrinta evelele ngenkathi zisebenzisa ukukhiqizwa kwepuleti le-resin okuphumelelayo kanye nobuchwepheshe bokuphrinta obuthuthukisiwe ukuze kuhlangatshezwane ngokugcwele nezidingo zokuphrinta amafilimu epulasitiki amakhulu. Kungakhathaliseki ukuthi kukhiqizwa njalo noma ku-oda oluphuthumayo, imishini yethu yokuphrinta ye-flexo ivumela izinguquko zepuleti ezisheshayo kanye nokuphrinta okusheshayo, okuqinisekisa ukukhiqiza okuphezulu kanye nokusebenza kahle, okunikeza ukwesekwa okuthembekile kokukhiqiza kwakho okukhulu.
Eminyakeni yamuva nje, intuthuko kwezobuchwepheshe be-flexo, njengobuchwepheshe bamachashazi aphezulu kanye nokusetshenziswa kabanzi kwamapuleti aqoshwe nge-laser, kuthuthukise kakhulu ukunemba kokuphrinta, kwaze kwafana nemininingwane emincane yokuphrinta nge-gravure. Kuhlanganiswe nezinzuzo ezingokwemvelo ze-flexo—imibala egqamile kanye nezendlalelo zoyinki ezifanayo—ukuphrinta kwefilimu yepulasitiki manje kuveza imiphumela emihle kakhulu, okuthuthukisa ngempumelelo ukukhanga komkhiqizo emashalofini.
Kusukela ekwenzeni ngcono izinqubo kuya ezindinganisweni ezinobungani nemvelo, kanye nasekulawulweni kwezindleko kuya ekhwalithini yokuphrinta, ukuphrinta kwe-flexo kubonisa izinzuzo ezingenakuphikwa emkhakheni wamafilimu epulasitiki. Akugcini nje ngokuhlangabezana nezidingo zamanje zemakethe zokuphrinta okusheshayo, okunobungani nemvelo, kanye nokonga imali kodwa futhi kuyaqhubeka nokuhola izitayela zemboni ngokusebenzisa ubuchwepheshe obusha. Ezinkampanini zokupakisha, ukukhetha umshini wokunyathelisa we-flexo kusho ukuncintisana okukhulu kanye nekusasa elizinzile.
