1. Ushicilelo
Indlela yokushicilela ibizwa ngokuba yi-gravure printing. Eyahlukileyo kushicilelo lwedijithali, ukuprintwa kwegravure kufuna iisilinda zokuprinta. Sikrola uyilo kwiisilinda ngokusekwe kwimibala eyahlukeneyo, kwaye emva koko sisebenzise i-inki ehambelana nokusingqongileyo kunye nebakala lokutya lokuprinta. Iindleko zesilinda zixhomekeke kwiintlobo zeengxowa, ubungakanani kunye nemibala, kwaye yindleko yexesha elinye, kwixesha elizayo xa ucwangcisa kwakhona uyilo olufanayo, akukho xabiso le-cylinder. Ngelixa ngokuqhelekileyo siya kugcina iisilinda iminyaka emi-2, ukuba emva kweminyaka emi-2 akukho kulungelelaniswa kwakhona, iisilinda ziya kuchithwa ngenxa ye-oxidation kunye nemiba yokugcina. Ngoku sifumana oomatshini bokushicilela aba-5 besantya esiphezulu, abanokushicilela imibala eyi-10 ngesantya seemitha ezingama-300/min.

2. Laminating
Ibhegi eguquguqukayo ikwabizwa ngokuba yi-laminated bag, i-cos ibhegi ebhetyebhetye kakhulu i-laminated ene-2-4 layers. I-Lamination kukuzalisekisa isakhiwo sengxowa yonke, ukufezekisa ukusetyenziswa komsebenzi wesikhwama. Umaleko ongaphezulu ngowokushicilela, ubukhulu becala osetyenziswa yi-matt BOPP, i-PET ecwebezelayo, kunye ne-PA (inayiloni); umaleko ophakathi ngowokusetyenziswa okusebenzayo kunye nomba wenkangeleko, njenge-AL, i-VMPET, i-kraft paper, njl. umaleko wangaphakathi wenza ubukhulu buphela, kwaye ukwenza ibhegi ibe namandla, iqhwa, ivacuum, i-retor, njl njl, izinto eziqhelekileyo yi-PE kunye ne-CPP. Emva kokushicilela kuluhlu lwangaphandle, siya ku-laminated phakathi kunye nomgangatho wangaphakathi, kwaye emva koko u-laminated kunye nomgangatho wangaphandle.

3. Ukuqinisa
Ukuqinisa, yinkqubo yokubeka ifilimu elaminated kwigumbi lokumisa ukwenza i-agent ephambili kunye ne-agent ephilisayo ye-adhesive polyurethane iphendule kunye ne-cross-link kunye nokusebenzisana nomphezulu we-substrate edibeneyo. Injongo ephambili yokuqinisa kukwenza i-arhente eyintloko kunye ne-ejenti yokunyanga iphendule ngokupheleleyo kwixesha elithile ukuze kuphunyezwe amandla adibeneyo adibeneyo; okwesibini kukususa i-solvent eshiyekileyo enendawo yokubila ephantsi, efana ne-ethyl acetate. Ixesha lokuqinisa lisuka kwiiyure ezingama-24 ukuya kwiiyure ezingama-72 kwizinto ezahlukeneyo.
4. Ukusika
Ukusika kuyisinyathelo sokugqibela sokuvelisa, ngaphambi kwesi sinyathelo, kungakhathaliseki ukuba luhlobo luni lweengxowa oziyalelayo, lulo lonke umqulu. Ukuba uyalela imiqulu yefilimu, ngoko siya kuzicanda nje zibe nobukhulu obufanelekileyo kunye nobunzima, ukuba uyala iingxowa ezihlukeneyo, ngoko ke linyathelo esilisongayo kwaye silinqumle libe ngamaqhekeza, kwaye kwakhona eli linyathelo songeza i-zipper, i-hang hole, i-notch yokukrazula, isitampu segolide, njl. Kwakhona ukuba u-odola iibhegi ezimile, eli ikwalinyathelo esisebenzisa ukungunda ukugoba kwimilo eyiyo oyifunayo.
