Lub hauv paus ntsiab lus tseem ceeb ntawm ua ntej-coated films yog nyob rau hauv kev siv cov nplaum xws li kub yaj nplaum nplaum, dej-raws li adhesives, los yog siab- cov nplaum nplaum kom ruaj khov rau zaj duab xis rau hauv substrate (xws li ntawv, yas, los yog hlau), tsim cov qauv sib xyaw nrog kev tiv thaiv, kev ua haujlwm, kev ua haujlwm. Qhov zoo tshaj plaws ntawm cov yeeb yaj kiab ua ntej-coated films yog tias lawv tshem tawm ntawm -site adhesive daim ntawv thov kauj ruam, txhim kho kev tsim khoom thiab txo qhov tsis zoo ntawm cov organic compound (VOC) emissions, ua raws li ib puag ncig.
Hom pre-coated zaj duab xis yog txiav txim siab los ntawm hom nplaum, cov khoom siv zaj duab xis, thiab txheej txheem txheej. Piv txwv li, kub yaj ua ntej-coated zaj duab xis ua tiav kev sib txuas los ntawm cua sov, feem ntau nrog qhov kub thiab txias ntawm -20℃thiab 80 degree, haum rau cov ntawv thov uas yuav tsum tau tiv thaiv qhov kub thiab txias, xws li cov ntim khoom noj thiab cov ntawv sau tshuaj. Siab- cov yeeb yaj kiab ua ntej-coated, ntawm qhov tod tes, tsis tas yuav tsum tau cua sov thiab sib txuas ncaj qha los ntawm lub siab, feem ntau siv rau hauv thaj chaw uas muaj kev ua haujlwm siab, xws li cov khoom siv hluav taws xob thiab cov tsheb sab hauv. Hais txog cov ntaub ntawv zaj duab xis, polyester (PET) puag zaj duab xis muaj lub zog siab thiab pob tshab, thaum polyethylene (PE) cov yeeb yaj kiab hauv paus, vim lawv qhov kev hloov pauv tau zoo, yog qhov tsim nyog rau kev sib txuas rau qhov nkhaus lossis qhov tsis sib xws.
Cov yeeb yaj kiab ua ntej-coated yog tshwj xeeb tshaj yog nyob rau hauv lawv cov dej tsis zoo, plua plav, thiab kev puas tsuaj- cov khoom tiv taus. Kev ntim khoom noj ua piv txwv, ua ntej- cov yeeb yaj kiab coated tuaj yeem tsim cov txheej txheem airtight, thaiv cov pa oxygen thiab noo noo thiab ua rau lub neej ntev. Hauv cov khoom siv hluav taws xob lamination, lawv cov khoom siv plua plav tiv thaiv kev nkag mus rau hauv cov khoom, txhim kho kev ntseeg tau ntawm cov khoom. Thaum lub sij hawm kev thauj mus los, lawv cov kev puas tsuaj- tiv thaiv tsim kom txo tau qhov cuam tshuam ntawm cov khoom siv sab hauv los ntawm cushioning. Tsis tas li ntawd, pre-stretch ratio ntawm pre-coated zaj duab xis (xws li, 400%) ncaj qha cuam tshuam rau kev siv cov khoom siv; siab -stretch ratio cov khoom tuaj yeem txo cov kev siv zaj duab xis thaum tuav lub zog, yog li txo cov nqi.
