The invention belongs to the technical field of anti-counterfeiting products, and particularly relates to a
plastic film uncovering type special code anti-counterfeiting
label and a preparation methodthereof. A transparent PET layer, an
isolation layer, a printing layer, a white ink layer, an
adhesive layer and a
silicone oil paper layer are sequentially arranged from top to bottom. The special code anti-counterfeit
label can be uncovered and is divided into a stripping part and a reserved part, and the stripping part is a PET layer. The reserved bottom part sequentially comprises the
isolation layer, the printing layer, the white film layer and the
adhesive layer from top to bottom. According to the
plastic film uncovering type special code anti-counterfeiting
label, the special anti-counterfeiting code adopted in the printing layer is an invisible code which does not reduce the attractive appearance of a commodity
package, rapid and accurate recognition can be conducted, vector datacan be formed, and
batch processing printing of high-speed variable information can be conducted. When the anti-counterfeiting code is damaged by 75%, that is, the
isolation layer is damaged, and theanti-counterfeiting code is incomplete, the anti-counterfeiting code can still be read, the error correction rate is high, and the anti-counterfeiting code is not easy to copy.
