Multilayer labels yog cov ntawv tshwj xeeb uas muab cov ntawv thermal, txheej txheej PP, thiab tus kheej -cov ntaub ntawv nplaum los ntawm cov txheej txheem sib xyaw, feem ntau siv hauv kev xa khoom, hluav taws xob, thiab kev tiv thaiv- khoom cuav. Lawv cov qauv tsim yog nyob rau hauv kev ua tiav kev sib koom ua ke los ntawm cov txheej txheem txheej: txheej txheej saum toj kawg nkaus yog siv rau cov ntaub ntawv luam tawm, cov txheej txheem nruab nrab txhim kho cov qauv kev ruaj ntseg, thiab hauv qab txheej muab adhesion.
Ib tug raug multilayer daim ntawv lo qauv muaj peb txheej: sab saum toj txheej yog thermal ntawv, uas tsim xim los ntawm ib tug thermal cov tshuaj tiv thaiv, tso cai rau cov ntaub ntawv luam tawm yam tsis muaj ribbon; Cov txheej txheem nruab nrab yog PP (polypropylene) zaj duab xis, uas txhim kho cov kua muag tiv thaiv thiab tiv thaiv ya raws; thiab cov txheej hauv qab yog tus kheej - nplaum txheej, muab adhesion. Qee cov khoom lag luam kuj suav nrog kev tiv thaiv- txheej txheej cuav ntawm PP thiab tus kheej- txheej nplaum, txhim khu kev ruaj ntseg los ntawm kev tiv thaiv kev tiv thaiv- cov thev naus laus zis cuav (xws li fluorescent number case thiab microtext). Lawv qhov kev ua haujlwm kub yog -20℃txog 70 degree, tso cai rau lawv hloov mus rau qhov chaw huab cua; thiab cov qauv tsim nrog qhov ntsuas hluav taws xob qis dua 440V ua kom lawv muaj kev nyab xeeb hauv cov khoom siv hluav taws xob hluav taws xob.
