Txij li thaum lub tshav kub ntawm lub tshav kub yog lub thermoplastic zaj duab xis uas ncab thiab taw qhia thaum lub sij hawm ntau cov txheej txheem thiab yog thaum tshav kub-shrinked thaum siv. Yog li ntawd, txawm tias txoj kev luam ntawv yog siv rau kev luam ntawv, txoj kab thiab qhov kev hloov ntawm qhov khoom thiab qhov deformation uas tau tso cai rau txhua txoj kab ntawm cov duab ntawm cov hniav tom qab xuav qis los ua ntej tsim cov qauv deg, thiaj li los xyuas kom meej thawb mus rau hauv lub thawv, Ua kom rov zoo nkauj ntawm phau ntawv thiab barcodes.
1, kev coj ntawm tus qauv
Txawm hais tias seb lub tshav kub ntawm lub tshav kub yog gravure los yog flexographic, qhov luam tawm yog nyob hauv hom ntawv luam tawm, thiab yuav tsum muaj kev sib raug zoo nrog cov qauv kev coj ntawm lub phaj printing. Cov kauj ruam hauv zaj nkauj kuj tau sau tseg hnub no, thiab qhov no, qhov qauv ntawm lub phaj yuav tsum tau muab hloov.
2, theem ntawm tus qauv
Vim yog qhov shortcomings ntawm flexographic luam ntawv, yog hais tias tus ntsws zaj duab xis yog cov cim, daim duab duab yuav tsum tsis txhob zoo, thiab gravure printing yuav tsum tau muaj cov duab txheej dua.
3, qhov loj ntawm qhov tsim
Qhov sib quas zuag ntawm cov cua kub thav duab siv rau kev luam tawm yog 50% rau 52% thiab 60% rau 62%, 90% ntawm cov case tshwj xeeb, thiab 6% mus rau 8% nyob rau hauv longitudinal shrinkage. Txawm li cas los xij, thaum twg cov zaj duab xis luv thiag, nws tsis yog txwv los ntawm lub khob, thiab cov kab lus thiab txoj kev ntsug yog tsis ua tiav hlo. Yuav kom rov ua tiav ntawm qhov qauv, text thiab barcode tom qab shrinking, cov duab ntawm lub thawv yuav tsum tau muab coj los xav, thiab qhov luaj li cas thiab muab xam raws li qhov xwm txheej tiag tiag yuav tsum yog xam. Deformation tus nqi. Rau cov cua sov shrinkable cov ntawv uas yuav tsum tau tsim rau hauv lub cylindrical duab thiab kaw los ua ke los ntawm kev siv lub nplaum, nws yog ib qhov tsim nyog yuav tau them sai sai rau qhov tseeb tias daim duab tsis tsim nyob rau hauv sealing feem, yog li ntawd raws li tsis mus cuam tshuam lub tsev khi ceev ceev.
4, qhov kev tso kawm ntawm tus qauv barcode
Feem ntau, txoj cai hauv lub npav yuav tsum muab tso rau tib qho chaw raws li kev luam ntawv. Txwv tsis pub, txoj cai bar code yuav raug muab sib cais, uas yuav cuam tshuam rau qhov ua kom tiav thiab ua yuam kev. Tsis tas li ntawd, xim xaiv ntawm daim ntawv lo khoom yuav tsum tau raws li qhov chaw xim ntau li ntau tau, thiab cov dawb version ntawm qhov tsim nyog yog tsim nyog, thiab tuaj yeem ua kom tiav los yog khoob raws li qhov tseeb qhov teeb meem. Rau cov xim ntawm cov khoom siv barcode, nws yog qhov yuav tsum ua raws li cov qauv kev cai, uas yog, cov xim sib txawv ntawm lub sawb thiab khoob yuav tsum yoog raws li txoj cai ntawm cov xim barcode. Sau cov khoom xaiv. Cov ntawv luam ntawm tshav kub-shrinkable daim ntawv tau luv luv ntsuas, cuam tshuam nws zoo. Ntxiv nrog rau kev tswj cov txheej txheem luam ntawv, cov ntaub ntawv ua yeeb yam tseem ceeb. Yog li ntawd, xaiv cov khoom yog qhov tseem ceeb. Lub thickness ntawm cov ntaub ntawv zaj duab xis yog txiav txim siab raws li daim ntawv thov ntawm lub tshav kub thawv ntawv, qhov nqi, tus yam ntxwv ntawm zaj duab xis, cov khoom ntim, cov txheej txheem luam ntawv, thiab cov txheej txheem kev sau npe. Feem ntau, zaj duab xis thickness ntawm shrink zaj duab xis yuav tsum yog 30 micrometers mus rau 70 micrometers, thiab 50 micrometers, 45 micrometers, thiab 40 micrometers feem ntau siv, nyob ntawm txoj kev labeling kev kawm ntawm lub labeling ntaus ntawv. Rau cov ntawv pov thawj xaiv, cov thim ntawm cov khoom siv yog feem ntau yuav tsum tau nyob rau hauv daim ntawv thov, thiab lub transverse (TD) shrinkage yog siab tshaj qhov longitudinal (MD) shrinkage. Cov khoom siv khov ntawm cov khoom siv feem ntau yog 50% txog 52% thiab 60% rau 62%, thiab 90% hauv qee qhov tshwj xeeb. Lub qhov txhab ntsws ntev yuav tsum yog 6% mus rau 8%. Tsis tas li ntawd, txij li thaum lub zuag zaj duab xis yog rhiab heev rau cua sov, nws yog ib qho tseem ceeb kom tsis txhob muaj peevxwm thaum muaj kev cia, luam ntawv, thiab kev thauj mus los.
