Plastic film uncovering type special code anti-counterfeit label and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeit products, and in particular relates to a plastic film peel-off special code anti-counterfeit label and a preparation method thereof. Background technique [0002] At present, two-dimensional code has been widely used in all walks of life and people's daily life. It can be quickly read by a reader with a camera. Compared with the previous barcode, two-dimensional code can store more abundant information, but two-dimensional Code still faces its own problems and challenges from the outside world. [0003] Since the two-dimensional code is square and printed directly on the flat substrate in black and white, this has a huge impact on the aesthetics of some products, and the two-dimensional code visible to the naked eye is easy to be copied, and the security is not high. Existing two-dimensional codes are printed on commodities or other carriers in black and white, and are visible to the nak...

Problems solved by technology

[0005] The problem with the existing peel-off anti-counterfeiting labels is that due to many objective factors in the peel-off type, there will be a phenomenon of peeling off the two-dimensional code, and because the error correction rate of most two-dimensional codes is 15%, as long as the two-dimensional code is destroyed A positioning point, it is easy to cause the QR code to be unreadable, and bring some unnecessary losses to consumers
