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.Ixabiso le-cylinder lixhomekeke 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 bubonke, kwaye ukwenza ibhegi ibe namandla, ikhenkceziswe, ivacuum, irhoxe, njalo njalo, izinto eziqhelekileyo yiPE kunye neCPP.Emva kokushicilela kuluhlu lwangaphandle, siya ku-laminated phakathi kunye ne-inner layer, kwaye emva koko i-laminated nge-layer yangaphandle.

3. Ukuqinisa
Ukuqinisa, yinkqubo yokubeka ifilimu elaminethiweyo kwigumbi lokumisa ukwenza i-agent ephambili kunye ne-agent ephilisayo ye-polyurethane adhesive adhesive and cross-link and interact with the surface of the composite substrate.Injongo ephambili yokuqinisa kukwenza i-arhente eyintloko kunye ne-ejenti yokunyanga iphendule ngokupheleleyo kwixesha elithile ukuze kufezekiswe amandla 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 oziyaleleyo, lulo lonke umqulu.Ukuba uodola imiqulu yefilimu, ke siya kuzicanda zibe yimilinganiselo efanelekileyo kunye nobunzima, ukuba uodola iingxowa ezahlukeneyo, ngoko linyathelo esilisongayo kwaye silinqumle zibe ziingceba, kwaye eli linyathelo esongeza i-zipper, i-hang hole. inotshi yokukrazula, isitampu segolide, njalo njaloKwakhona ukuba u-odola iibhegi ezimile, eli ikwalinyathelo esisebenzisa ukungunda ukugoba ukuba libe kwimilo eyiyo oyifunayo.
