Cov txheej txheej sab nraud ntawm tus kheej- daim ntawv luam ntawv nplaum yog txheej txheej luam ntawv, uas yog ib feem ntawm daim ntawv lo ncaj qha nqa cov ntaub ntawv. Cov txheej txheem luam ntawv tuaj yeem yog daim ntawv, ntawv thermal, lossis zaj duab xis hluavtaws (xws li PET, PP, PE). Qhov saum npoo feem ntau yog coated los txhim kho kev luam tawm, ua kom pom tseeb ntawm cov ntawv nyeem, barcodes, QR cov lej, lossis cov qauv. Cov ntaub ntawv sib txawv rau cov txheej txheem luam ntawv muaj cov yam ntxwv sib txawv: daim ntawv saum npoo yog tsim rau luv luv - siv sijhawm ntev thiab kev luam ntawv dav dav, thaum cov khoom siv hluavtaws yog dej- tiv taus, abrasion- resistant, thiab chemically resistant, haum rau ntev - siv los yog muaj ib puag ncig.
Hauv qab txheej txheej luam ntawv yog txheej nplaum (siab- cov nplaum nplaum), uas yog qhov tseem ceeb uas ua rau tus kheej - nplaum ntawv luam ntawv ua haujlwm. Cov nplaum nplaum feem ntau yog siv lub siab- cov ntaub nplaum nplaum, uas muaj cov yam ntxwv ntawm adhering yooj yim ntawm chav tsev kub. Cov nplaum nplaum tuaj yeem muab faib ua cov nplaum ruaj khov, tshem tau cov nplaum, lossis rov siv tau dua, nyob ntawm lawv daim ntawv thov. Ntau hom nplaum nplaum tuaj yeem ua tau raws li qhov sib txawv adhesion zog thiab kev siv ib puag ncig, xws li ntev - fixation, daim ntawv lo rau ib ntus, lossis rov siv dua. Cov txheej hauv qab yog cov ntaub ntawv tso tawm lossis cov ntaub ntawv tiv thaiv, siv los tiv thaiv kev ncaj ncees ntawm cov nplaum txheej thaum khaws cia thiab kev thauj mus los. Cov ntawv thaub qab feem ntau yog coated nrog silicone roj los yog ib zaj duab xis du, uas ua rau nws yooj yim rau tev tawm, tso cai rau daim ntawv lo kom yooj yim tev tawm thiab tiaj tus nrog rau lub hom phiaj nto thaum siv.
