There are many categories of anti-counterfeiting labels. Currently, the most commonly used categories include the following categories. Here are their basic characteristics: And the scope of use is introduced as follows:
1. Holographic anti-counterfeiting label, also known as laser anti-counterfeiting label, or laser anti-counterfeiting label. During holographic plate making, graphic information is burned onto the photolithography film with a non-interfering light beam, and then post-production is performed to make the photolithographic part of the anti-counterfeiting mark have a diffractive visual effect of metallic light rotation and diffusion. It is mainly used in some electronic products, and is also used in other industries, such as shopping cards in shopping malls, VIP cards, etc.
2. Dual-card anti-counterfeiting labels; there are four types of dual-card anti-counterfeiting labels: moiré striped dual-card, nuclear-track dual-card, polarized optical dual-card, random encrypted hidden image and text dual-card. This is a relatively high-end anti-counterfeiting label, often used in some high-end consumer products.
3. Nuclear microporous anti-counterfeiting label, that is, nuclear track anti-counterfeiting. Irradiation of organic films by imaging methods from heavy ion generators or nuclear reactors (state-controlled equipment) causes ionization damage. Use strong alkali or acid to etch the formed tracks into micropores. Graphics and text are composed of micropores. Its anti-counterfeiting features are: under visible light, due to micropore diffraction and scattering, the visual effect observed by the human eye is white graphics and text. If water drips on it, the water will seep into the micropores and the pictures and text will disappear. If it is applied with colored liquid, the colored liquid will penetrate into the micropores, wipe off the colored liquid on the surface, and colored graphics and text will appear.
