核径迹综合防伪标识介绍:Introduction of nuclear track integrated anti-counterfeiting mark: 核径迹综合防伪标识图案由每平方厘米几十万到几百万个微米级微孔组成。微孔在光线下反射形成白色图案。微孔孔径很小,孔数很多,微孔在平面上按统计规律分布,孔道为圆柱形,具有良好的透气、透水性能。通过模拟试验,证明利用激光打孔或机械加工手段,无法制得和核微孔防伪膜类似的产品。The nuclear track comprehensive anti-counterfeiting mark pattern consists of hundreds of thousands to millions of micron-sized micropores per square centimeter. The micropores
