1. Kev luam ntawv
Txoj kev luam ntawv yog hu ua gravure printing.Sib txawv ntawm cov luam ntawv digital, gravure printing xav tau lub tog raj kheej rau luam ntawv.Peb muab cov qauv tsim rau hauv lub tog raj kheej raws li cov xim sib txawv, thiab tom qab ntawd siv tus phooj ywg ib puag ncig thiab zaub mov qib number case rau luam ntawv.Lub tog raj kheej tus nqi nyob ntawm lub hnab hom, qhov ntau thiab tsawg thiab xim, thiab nws tsuas yog tus nqi ib zaug xwb, lwm zaus thaum koj rov txiav txim dua tus qauv tsim, tsis muaj nqi ntxiv.Thaum ib txwm peb yuav khaws cov thooj voos kheej kheej rau 2 xyoos, yog tias tom qab 2 xyoos tsis muaj kev txiav txim rov qab, lub tog raj kheej yuav raug muab pov tseg vim muaj teeb meem oxidation thiab khaws cia.Tam sim no peb tau txais 5 lub tshuab luam ntawv siab ceev, uas tuaj yeem luam 10 xim nrog qhov ceev ntawm 300 meters / min.

2. Laminating
Lub hnab ntim tau kuj hu ua lub hnab laminated, cos lub hnab hloov pauv feem ntau yog laminated nrog 2-4 txheej.Lamination yog ua kom tiav cov qauv ntawm lub hnab tag nrho, kom ua tiav qhov kev siv ntawm lub hnab.Nto txheej yog rau luam ntawv, feem ntau yog siv matt BOPP, ci iab tus tsiaj, thiab PA (nylon);nruab nrab txheej yog rau qee qhov kev siv thiab qhov teeb meem zoo li, xws li AL, VMPET, kraft ntawv, thiab lwm yam;puab txheej ua rau tag nrho cov tuab, thiab ua kom lub hnab kom muaj zog, khov, nqus tsev, retort, thiab lwm yam, cov khoom siv yog PE thiab CPP.Tom qab luam tawm ntawm txheej txheej sab nraud, peb yuav laminated nruab nrab thiab sab hauv txheej, thiab tom qab ntawd laminated nrog txheej sab nraud.

3. Solidifying
Solidifying, yog cov txheej txheem ntawm muab cov zaj duab xis laminated rau hauv chav ziab kom ua tus neeg sawv cev tseem ceeb thiab kho tus neeg sawv cev ntawm polyurethane adhesive react thiab cross-links thiab cuam tshuam nrog cov khoom sib xyaw substrate.Lub hom phiaj tseem ceeb ntawm kev ua kom muaj zog yog ua kom tus neeg sawv cev tseem ceeb thiab tus neeg sawv cev kho mob siab rau hauv ib lub sijhawm kom ua tiav qhov zoo tshaj plaws sib xyaw zog;Qhov thib ob yog tshem tawm cov residual hnyav uas tsis tshua muaj boiling point, xws li ethyl acetate.Solidifying lub sij hawm yog los ntawm 24 teev mus rau 72 teev rau cov khoom sib txawv.
4. Txiav
Kev txiav yog cov kauj ruam kawg rau kev tsim khoom, ua ntej cov kauj ruam no, txawm tias hom hnab twg koj xaj, nws yog nrog tag nrho yob.Yog tias koj xaj zaj duab xis yob, ces peb yuav cia li hlais rau hauv qhov loj thiab qhov hnyav, yog tias koj xaj cov hnab cais, ces qhov ntawd yog cov kauj ruam peb quav thiab txiav rau hauv daim, thiab qhov no yog cov kauj ruam peb ntxiv zipper, dai qhov, tear notch, kub stamp, thiab lwm yam. Muaj cov tshuab sib txawv raws li lub hnab sib txawv - lub hnab pav ca, sawv ntsug lub hnab, sab gusset hnab thiab lub hnab ca hauv qab.Tsis tas li yog tias koj xaj cov hnab zoo li no, qhov no kuj yog cov kauj ruam uas peb siv pwm los nkhaus rau hauv cov duab zoo uas koj xav tau.
