1. Laser holographic stickers
This type of label is very convenient to use, and can be completely glued to other locations after being removed from one location. Because it can be used repeatedly, the anti-counterfeiting effect is lost, so the scope of application is limited.
2. Laser holographic tamper-evident
Also known as one-time laser holographic label, when the label is removed from the package, the pattern is already incomplete, can not be used again, can not be copied, played a very good anti-counterfeiting role, and made up for the shortcomings of the self-adhesive laser holographic label, It is the most promising one in the field of laser holographic label.
3. Laser holographic hot stamping type
It is to stick the laser holographic label tightly and completely to the packaged object, forming an integral part with it, and cannot be removed. If the label sticking position is reasonable, a good anti-counterfeiting effect can be exerted, and there are many applications at present.
The laser holographic label can also be encrypted to improve the technical content of the laser holographic label. The main encryption methods are: low-frequency lithography, laser reading, optical miniaturization, random interference fringes, moiré fringe methods, etc. Some of the encryption methods are difficult to identify and can play a good anti-counterfeiting role.
