Self-adhesive labels yog ib qho tseem ceeb luam ntawv ntau yam siv dav hauv cov khoom ntim khoom, tsheb thauj mus los, thiab ntau yam kev qhia. Hauv self-adhesive daim ntawv luam, lamination yog qhov txuas tseem ceeb heev. Nws tuaj yeem tiv thaiv daim ntawv lo, txhim khu durability, thiab txhim kho kev zoo nkauj, yog li ntawd txhim kho lub neej kev pab cuam thiab zoo ntawm tus kheej-nplaum daim ntawv lo. Kab lus no yuav qhia txog cov txheej txheem lamination thiab cov txheej txheem ntawm cov ntawv nplaum rau tus kheej tom qab luam ntawv, aiming pab cov nyeem kom nkag siab txog cov txheej txheem lamination sib txawv, cov ntsiab lus technical, thiab xaiv cov khoom siv, nrog rau yuav ua li cas los tswj cov txheej txheem lamination kom raug kom zoo thiab kev ntseeg tau.
Lub luag haujlwm ntawm Label Lamination
Label overlays yog siv los tiv thaiv cov ntawv los ntawm ib puag ncig kev puas tsuaj xws li dej, UV rays, puas, lwm. Los ntawm kev ntxiv cov yeeb yaj kiab tiv thaiv meej rau saum npoo ntawm daim ntawv lo, koj tuaj yeem txuas lub neej ntawm daim ntawv lo thiab khaws nws cov tsos kom meej. Label laminations tuaj yeem txhim kho daim ntawv lo kom ruaj khov thiab tiv thaiv cov duab lossis cov ntawv ntawm cov ntawv los ntawm kev ploj mus dhau sijhawm. Laminates kuj muab kev tiv thaiv ntxiv, xyuas kom cov ntawv tsis raug puas thaum lub sij hawm xa khoom thiab khaws cia. Tag nrho cov txiaj ntsig no tuaj yeem txhim kho cov neeg siv khoom, yog li no txhim khu kev paub txog hom lag luam.
Laminated Khoom
Lub lamination ntawm daim ntawv lo rau tus kheej feem ntau siv cov ntaub ntawv hauv qab no:
Polyester Zaj duab xis (PET): Cov khoom no yog ruaj thiab dej-resistant, thiab nws muab kev luam ntawv zoo ntawm cov duab thiab cov ntawv.
Polypropylene zaj duab xis (PP): Lub teeb thiab pob tshab heev, cov khoom no muab cov txheej txheem tiv thaiv zoo. Composite tag nrho pob tshab PP zaj duab xis yog tam sim no cov khoom siv dav tshaj plaws. Yog vim li cas yog tias PP yog tus nqi qis thiab ruaj khov dua li ob peb lwm cov ntaub ntawv.
Polyvinyl Chloride Zaj duab xis (PVC): Cov khoom no yog kev lag luam, tab sis kuj tsis tshua muaj kev phooj ywg zoo dua li cov ntaub ntawv PET lossis PP.
Polyethylene zaj duab xis (PE): Cov khoom no yog mos thiab haum rau daim ntawv lo lamination ntawm nkhaus los yog tsis xwm yeem.
Raws li cov kev xav tau ntawm cov nqi, txheej ntawm daim ntawv yob cov ntaub ntawv yog hloov los ntawm glazing technology. Hauv kev lag luam daim ntawv lo, thaum cov kua roj vanish tsis tuaj yeem ua tau raws li qhov xav tau ntawm qhov ci thiab matte, lamination yog txoj kev ncaj tshaj plaws. Peb tuaj yeem xaiv cov khoom siv lamination tsim nyog raws li qhov sib txawv ntawm daim ntawv thov kom paub meej tias daim ntawv lo tau txais kev tiv thaiv zoo tshaj plaws thiab kav ntev..
Txoj Kev Laminating
Daim ntawv lo lamination txoj kev feem ntau muab faib ua cov ntawv lamination thiab yob cov khoom lamination. Daim ntawv-piv ntawv yog laminated ntawm lub tshuab laminating, thiab cov ntaub ntawv yob yog laminated ntawm qhov chaw nres tsheb laminating ntawm lub tshuab daim ntawv lo lossis ntawm lub tshuab laminating tshwj xeeb. Ob txoj kev txheej txheej tau piav qhia hauv qab no:
- Sheetfed Laminated
Sheetfed lamination suav nrog muab cov ntawv tso rau ntawm ib daim ntawv ntawm cov khoom siv lamination thiab siv cov cua sov thiab siab los khi cov lamination thiab daim ntawv lo ua ke. Txoj kev no yog tsim rau cov xwm txheej uas ib tus neeg yuav tsum tau laminated, xws li thaum daim ntawv lo muaj ntau qhov sib txawv los yog yuav tsum tau tuav tshwj xeeb rau cov ntawv. Sheetfed lamination tuaj yeem ua tau siv phau ntawv lossis tsis siv neeg laminators.
Muaj ob txoj hauv kev ntawm laminating daim ntawv pub rau nws tus kheej-nplaum daim ntawv lo, xws li instant txheej lamination thiab pre-txheej zaj duab xis lamination.
1)Cov txheej txheem sib xyaw ua ke ntawm instant txheej compounding yog raws li hauv qab no: ua ntej, cov nplaum yog coated rau saum npoo ntawm yob BOPP zaj duab xis, thiab cov kuab tshuaj nyob rau hauv cov nplaum yog volatilized los ntawm lub tshuab ziab khaub ncaws, thiab tom qab ntawd cov ntawv sau ua ke nrog cov yob zaj duab xis ntawm qhov chaw nres tsheb compounding. Composite, ob tug ua ib tug nyob rau hauv lub extrusion ntawm cov menyuam kub, thiab txheej txheem txheej txheej zaj duab xis tiav.
2)Pre-coated film composite refers to pre-coating a layer of adhesive or laminating material on the surface of the composite film. There are two types of films, hot melt adhesive type and pressure sensitive type. The laminating machine is equipped with a heated embossing roller, and the pre-coated film is in contact with the sheet of paper during lamination. Under the action of the hot pressing roller, the adhesive is melted, so that the film and the paper are bonded into one. If you use a pressure-sensitive composite film, you can turn off the heating power supply and only rely on pressure to composite.
- Roll Material Lamination
Roll material lamination is to print the roll material film and label together, and then pass them together through the laminating machine for heat and pressure treatment. Txoj kev no yog tsim rau kev tsim cov ntawv loj loj, uas tuaj yeem txhim kho kev tsim khoom thiab txo cov nqi. Lamination ntawm cov ntaub ntawv web tuaj yeem ua tiav hauv batch lossis kev tsim khoom tas mus li.
Web lamination feem ntau muab faib ua ob hom: bottomed paper composite film composite thiab bottomless paper composite film composite.
1)Backing paper composite film lamination hais txog kev sib xyaw ua ke ntawm cov ntawv thaub qab ntawm sab xub ntiag lossis sab nraub qaum ntawm daim ntawv yob, thiab tom qab ntawd txheej txheej ntawm cov nplaum los yog cov khoom laminating rau ntawm daim ntawv thaub qab, thiab mam li muab daim ntawv lo rau nws. Backed paper composite film lamination yog ib txwm lamination txoj kev, uas tau hloov los ntawm cov txheej txheem ntawm kev siv cov ntawv hauv qab uas tsis muaj cov ntawv sib xyaw ua ke hauv xyoo tas los no.
2)Lub hauv paus ntsiab lus ntawm laminating zaj duab xis uas tsis muaj daim ntawv hauv qab yog qhov pib zoo ib yam li cov zaj duab xis sib xyaw nrog cov ntawv hauv qab.. Cov ntaub ntawv thaub qab yog rov qab los ntawm qhov smoothness (nto nro) ntawm nws tus kheej cov khoom siv los hloov cov ntawv thaub qab. Tom qab cov nplaum yog khi rau saum npoo, nws tuaj yeem tev tawm yam tsis tau tawm hauv cov kua nplaum. Cov khoom siv rau cov ntawv hauv qab uas tsis muaj ntawv yog feem ntau yog qhov tsis tshua muaj BOPP zaj duab xis. Tus nqi ntawm cov ntawv hauv qab uas tsis muaj zaj duab xis lamination yog tsawg, thiab nws yog cov khoom siv lamination tshaj plaws nyob rau tam sim no. Qhov kom zoo dua ntawm cov ntawv hauv qab tsis muaj cov ntawv sib xyaw zaj duab xis yog tias nws tuaj yeem txhim kho kev tsim khoom, txo cov pov tseg hauv cov txheej txheem ntau lawm, thiab tib lub sijhawm txhim kho cov khoom zoo.
Tau kawg, txawm siv txoj kev lamination twg, txheej txheej tiv thaiv tuaj yeem tsim rau saum npoo ntawm daim ntawv lo los tiv thaiv daim ntawv lo ntawm ib puag ncig kev puas tsuaj.
Hauv self-adhesive daim ntawv luam, lamination yog ib kauj ruam tseem ceeb heev, vim nws tuaj yeem ua rau daim ntawv lo zoo nkauj dua, ruaj, thiab adaptable. Txoj kev lamination raug thiab xaiv cov khoom siv tuaj yeem ua kom zoo thiab kev pabcuam lub neej ntawm cov ntawv nplaum rau tus kheej. Yog li ntawd, cov tuam txhab luam ntawv thiab cov neeg siv yuav tsum tau them sai sai rau kev xaiv cov txheej txheem lamination thiab cov ntaub ntawv tsim nyog, thiab ua kom muaj kev tswj xyuas kom zoo los xyuas kom meej qhov kawg ntawm cov ntawv nplaum tus kheej.
