1、3、防偽長(zhǎng)絲：防偽長(zhǎng)絲：防偽長(zhǎng)絲產(chǎn)品直徑30微米-2000微米，具體分為三大類：一．無(wú)色熒光系列：自然光下無(wú)色（白），紫外燈照射下發(fā)出各色熒光；二、有色熒光系列：自然光下有各種顏色，紫外燈照射下發(fā)出另外一種顏色熒光；三、單根多色長(zhǎng)絲、多色段DNA色譜防偽長(zhǎng)絲、復(fù)合長(zhǎng)絲：可根據(jù)客戶需要定制顏色組合、色段長(zhǎng)度、纖維形狀。防偽長(zhǎng)絲的使用方法主要有四種：一是在紙的后加工中填埋或夾埋在紙與紙之間，用于防偽標(biāo)簽紙制造；二是在印刷包裝廠的覆膜工序中加在膜紙之間，用于高檔煙、藥、酒的防偽包裝盒制造；三是與香煙或藥品等包裝中的經(jīng)拉線復(fù)合，作為防偽標(biāo)記；四
2、是在證件、票據(jù)文本中作為裝訂線使用，作為防偽特征；也可根據(jù)客戶需要合作開發(fā)不同的使用環(huán)境。anti-counterfeitthread(anti-forgerythread,anti-clonethread,authenticationthread,tracingandtrackingthread,anti-theftthread,traceabilitythread,securitythread）Thethread'sdiameterisbetween50micrometersand200micrometers.Therearethr
