Technical Field

The invention relates to the technical field of anti-counterfeit labels, in particular to an easy-to-clean anti-counterfeit label.

Background

The label is used for displaying important information of the article. The label material has a structure comprising a face material, an adhesive and a base paper. The face stock carries important information about the product by printing or printing techniques. The adhesive is used as an important tie for connecting the surface material and the attached object.

The label material has wide application, and can be applied to daily chemical products, product packages, electronic products and automobiles. The label with a special function can play a role in displaying important information of a product and has some anti-counterfeiting functions, so that the functions of tracing, counterfeiting prevention, copying prevention, uncovering prevention, tampering prevention and the like are achieved.

At present, a plurality of anti-counterfeiting technologies are available, and the anti-counterfeiting technology is mainly realized on a label from the following aspects: special materials, special ink technology, information technology, VOID printing technology, anti-counterfeiting patterns and the like are adopted. The special material comprises a laser film, a fragile film, a nuclear pore film and the like. The security pattern includes: flower, lace, relief, latent image, micro-scale, etc. The information technology comprises the following steps: FIRD, two-dimensional code, three-dimensional code, algorithm technology, etc. The special ink technology comprises the following steps: light-variable ink, temperature-variable ink, fluorescent ink, color-variable ink at different angles and the like. Different anti-counterfeiting technologies have different application scenes and different use costs.

In order to guarantee the legitimate rights and interests of consumers, counterfeit commodities are attacked, and some anti-counterfeit labels are often stuck on electronic products. The prior anti-counterfeiting label mostly adopts pressure-sensitive adhesive to connect surface materials, and then a plurality of anti-counterfeiting technologies are manufactured on the surface materials. Because the glass transition temperature of the pressure-sensitive adhesive is lower, after heating, the high molecular chain segment of the pressure-sensitive adhesive becomes soft and slides, so that the viscosity of the pressure-sensitive adhesive is rapidly reduced. Therefore, if a lawless person exists, the anti-counterfeit label can be transferred and replaced by adopting a hot air blowing mode of a blower.

The common anti-counterfeit label is easy to remove by adopting a heating mode. To improve the resistance to removal, the pressure-sensitive adhesive thickness may be increased to raise the glass transition temperature of the pressure-sensitive adhesive, which may increase the difficulty of removal, but the label may be removed by heating for a time sufficient to remove the label.

Under a high-temperature state, the molecular chain of the pressure-sensitive adhesive slides and degrades, so that the cohesion of the pressure-sensitive adhesive is reduced, adhesive residues can be easily generated on an attached object, and the adhesive residues are difficult to clean, and therefore the anti-counterfeiting label easy to clean is provided.
