1、3、防偽長絲:防偽長絲:防偽長絲產(chǎn)品直徑30微米-2000微米,具體分為三大類:一.無色熒光系列:自然光下無色(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、單根多色長絲、多色段DNA色譜防偽長絲、復(fù)合長絲:可根據(jù)客戶需要定制顏色組合、色段長度、纖維形狀。防偽長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
