Dynamic color-changeable two-dimensional code anti-counterfeit label

Abstract

The invention discloses a dynamic color-changeable two-dimensional code anti-counterfeit label, and belongs to the domain. The dynamic color-changeable two-dimensional code anti-counterfeit label comprises a label body and a protection frame sleeving the outer side of the label body, the protection frame comprises a left frame and a right frame. Grooves are formed in the inner side walls of the left frame and the right frame; the label body is clamped in the grooves in the left frame and the right frame; a clamping structure is arranged at the joint of the left frame and the right frame; the label body comprises a transparent protective layer, a thermochromic layer, an anti-counterfeiting information layer, a base material layer, an adhesive layer and a release layer which are sequentiallyarranged from top to bottom; the anti-fake information layer is bonded to the upper surface of the base material layer, the temperature sensing color changing layer is bonded to the upper surface ofthe anti-fake information layer, the label body can be effectively protected, the protection frame can be rapidly clamped and detached, clamping is firm, detaching is convenient, various kinds of anti-fake information are contained, the anti-fake strength is high, and the anti-fake effect and sufficiency are guaranteed.

Description

technical field [0001] The invention relates to the technical field, and more specifically relates to a dynamic color-variable two-dimensional code anti-counterfeiting label. Background technique [0002] With the development of the economy, the demand for anti-counterfeiting labels in the product market is increasing. The anti-counterfeit label is pasted on the product, so that consumers can distinguish between genuine and imitation products. The anti-counterfeit label is a mark that can be pasted, printed, and transferred on the surface of the object, and has an anti-counterfeiting effect. The anti-counterfeiting features and identification methods of anti-counterfeiting labels are the main structure of anti-counterfeiting labels. Anti-counterfeiting is a preventive measure against counterfeiting or copying activities for the purpose of deception without the permission of the owner. [0003] With the provision of anti-counterfeiting performance, its imitation technology i...

AI Technical Summary

Problems solved by technology

[0003] With the provision of anti-counterfeiting performance, its imitation technology is also constantly improving, because a single anti-counterfeiting function can no longer meet the existing needs, and multiple anti-counterfeiting methods must be adopted to meet the needs of the current stage

The existing anti-counterfeiting labels have relatively simple anti-counterfeiting methods, low anti-counterfeiting strength, and do not have diversified anti-counterfeiting marks
