1. Ukuphrinta
Indlela yokuphrinta ibizwa nge-gravure printing.Ihlukile kokuphrinta kwedijithali, ukuphrinta kwe-gravure kudinga amasilinda ukuze kuphrintwe.Siqopha imiklamo kumasilinda ngokusekelwe emibaleni ehlukene, bese sisebenzisa uyinki ovumelana nemvelo kanye nebanga lokudla ukuze siphrinte.Izindleko zesilinda zincike ezinhlotsheni zezikhwama, osayizi nemibala, futhi kuyindleko yesikhathi esisodwa nje, ngokuzayo lapho uhlela kabusha idizayini efanayo, azisekho izindleko zesilinda.Nakuba ngokuvamile sizogcina amasilinda iminyaka engu-2, uma ngemva kweminyaka emi-2 singaphinde si-odwe kabusha, amasilinda azolahlwa ngenxa yezinkinga ze-oxidation nokugcinwa.Manje sithola imishini yokunyathelisa engu-5 enesivinini esikhulu, engaphrinta imibala engu-10 ngesivinini esingamamitha angu-300/min.

2. Laminating
Isikhwama esiguquguqukayo sibizwa nangokuthi isikhwama se-laminated, i-cos isikhwama esiguquguqukayo kakhulu sifakwe nge-2-4 izendlalelo.I-Lamination iwukugcwalisa ukwakheka kwesikhwama sonke, ukufeza ukusetshenziswa okusebenzayo kwesikhwama.Ungqimba olungaphezulu elokuphrinta, olusetshenziswa kakhulu yi-matt BOPP, i-PET ecwebezelayo, ne-PA (inayiloni);ungqimba olumaphakathi olokusetshenziswa okuthile nokubukeka, njenge-AL, i-VMPET, i-kraft paper, njll;ungqimba lwangaphakathi lwenza ukujiya okuphelele, nokwenza isikhwama sibe namandla, siqandiswe, sivale, sibuyisele emuva, njll, izinto ezijwayelekile yi-PE ne-CPP.Ngemva kokunyathelisa phezu ngaphandle ungqimba surface, sizobe laminated ungqimba maphakathi nangaphakathi, bese laminated nabo nge ungqimba ngaphandle.

3. Ukuqinisa
I-Solidifying, inqubo yokufaka ifilimu elaminethiwe ekamelweni lokumisa ukuze wenze i-ejenti eyinhloko kanye ne-ejenti elaphayo ye-polyurethane adhesive isabela futhi ixhumane futhi ixhumane nobuso be-substrate eyinhlanganisela.Inhloso eyinhloko yokuqinisa ukwenza i-ejenti eyinhloko kanye ne-ejenti elaphayo basabele ngokugcwele phakathi nenkathi ethile yesikhathi ukuze kuzuzwe amandla ahlanganisiwe angcono kakhulu;okwesibili ukususa i-solvent esele enephuzu eliphansi lokubilisa, njenge-ethyl acetate.Isikhathi sokuqinisa sisuka emahoreni angama-24 kuye kwangama-72 sezinto ezahlukahlukene.
4. Ukusika
Ukusika kuyisinyathelo sokugcina sokukhiqiza, ngaphambi kwalesi sinyathelo, kungakhathaliseki ukuthi hlobo luni lwezikhwama oziyalile, lunomqulu wonke.Uma u-oda imiqulu yefilimu, sizovele siwahlukanise ngosayizi nezisindo ezifanele, uma u-oda izikhwama ezihlukene, leso yisinyathelo esisigoqa futhi sisike sibe yizicucu, futhi lesi yisinyathelo esengeza i-zipper, i-hang hole, I-notch edabukile, isitembu segolide, njll. Kukhona umshini ohlukene ngokwezinhlobo zezikhwama ezihlukene-isikhwama esiyisicaba, isikhwama sokumisa, isikhwama segusset esiseceleni kanye nezikhwama eziphansi eziyisicaba.Futhi uma u-oda izikhwama ezinomumo, lesi futhi isinyathelo esisebenzisa isikhunta ukuze sizigoqe zibe sesimweni esifanele osidingayo.
