Dej Barrier Ntawv

Daim ntawv thaiv dej yog cov khoom ntim khoom zoo ib puag ncig uas tsim los ntawm kev siv ntau- txheej dej-raws li polymer txheej rau cov ntawv cog lus nkauj xwb, hloov cov txheej txheem PE extrusion lamination, yas lamination, thiab cov txheej txheem aluminium foil lamination. Cov khoom siv tsis muaj extrusion txheej, tsis muaj yas zaj duab xis lamination, thiab tsis muaj txhuas ntawv ci. The coating forms a dense high-barrier layer on the paper surface, providing integrated high oxygen barrier, high moisture barrier, high grease resistance, and liquid and gas barrier properties. Cov txheej yog dej-raws li thiab tsis muaj cov yas interlayers. Feem ntau cov qhab nia tuaj yeem ua tiav los ntawm cov txheej txheem cov ntawv rov ua dua tshiab lossis kev tsim cov khoom sib xyaw. Qhov no ua rau cov ntawv thaiv dej tsis zoo rau cov yas laminates, aluminium foil ntawv, thiab ntawv coated.

Qhov tseem ceeb sib txawv ntawm nws thiab cov ntawv coated ib txwm nyob hauv cov txheej txheem thaiv. PE-coated ntawv cia siab rau ib txheej zaj duab xis yas rau dej thiab roj tsis kam, tab sis daim ntawv- cov yas sib cais ua rau rov ua dua nyuaj. Daim ntawv thaiv dej siv dej -raws li txheej kom ua tiav cov haujlwm thaiv. Tom qab muab pov tseg, txheej txheej disperses thaum lub sij hawm repulping, cia cov ntawv fibers yuav tsum recycled ib txwm tsis muaj tshwj xeeb sorting. Barrier kev ua tau zoo tuaj yeem kho tau. High-moisture- cov qib barrier zoo thaiv cov pa ya raws, tiv thaiv cov ntsiab lus los ntawm kev ntub dej. High-oxygen- cov qib barrier qeeb roj oxidation thiab zaub mov lwj, ua rau lub neej ntev. Siab- roj- cov qib tiv taus ua tiav cov khoom siv siab- qib roj tsis kam, thaiv cov roj ua noj thiab cov ntses nkag. Cov qib xaiv tau txhawb cov cua sov- sealing thiab sib xws nrog cov khoom ntim tsis siv neeg. Qhov hnyav ntawm qhov hnyav yog 45 txog 200 grams. Cov ntaub ntawv muab khoom muaj xws li yob, nplooj ntawv, thiab ua ntej- txiav cov xim dawb thiab xim av.
