Embodiment 1

[0023] This embodiment provides a tamper-evident anti-counterfeit label, which includes a first ink layer 1, a release film layer 3, a sequin layer 4, an adhesive layer 5 and a protective layer 6, and each layer is stacked sequentially from top to bottom.

[0024] The first ink layer 1 is a two-dimensional code pattern printed with ink, the two-dimensional code pattern is random, and is printed on the surface of the release film layer 3 by a digital printing machine. In this embodiment, a random two-dimensional code is taken as an example for illustration, and the actual first ink layer 1 may also be a frame, characters, numbers or any combination thereof.

[0025] The release film layer 3 is a transparent and printable film made of PET (polyethylene terephthalate), opp (o-phenylphenol), pe (polyethylene), pp (polypropylene) and the like.

[0026] The sequin layer 4 is composed of several color-changing particles and / or flashing particles, forming random patterns or patterns. ...

Embodiment 2

[0033] This embodiment provides a method for manufacturing an anti-tamper type anti-counterfeit label, corresponding to Embodiment 1, the manufacturing method includes the following steps,

[0034] Step 1, on the protective layer 6, apply glue with a coating machine to form an adhesive layer 5;

[0035] Step 2. Spray or sprinkle powder on the surface of the adhesive layer 5, so that the discoloration particles and / or glitter particles are randomly distributed on the adhesive layer 5 to form the sequin layer 4;

[0036] Step 3, enter the oven to dry the glue, so that the sequin layer 4 and the adhesive layer 5 are firmly combined;

[0037] Step 4, the release film layer 3 and the sequin layer 4 are pressed together by a roller pressing device;

[0038] Step 5, printing a randomly generated two-dimensional code on the surface of the release film layer 3 to form the first ink layer 1 .

[0039] Preferably, the color-changing particles and / or glitter particles described in step ...

Abstract

The invention discloses a tamper-evident anti-counterfeit label and a manufacturing method thereof. The tamper-evident anti-counterfeit label comprises a first ink layer printed with a graphic mark, atransparent release film layer, a paillette layer distributed with color-changing particles and / or flashing particles, a bonding layer and a protective layer, and the first ink layer, the release film layer, the paillette layer, the bonding layer and the protective layer are sequentially distributed, wherein the paillette layer and the bonding layer are different in color. According to the invention, the first ink layer with the graphic mark is arranged on the release film layer; the position, covered by the first ink layer, of the label presents the graphic mark; a random paillette pattern is presented at a position which is not covered by the first ink layer, namely, random structure characteristics of different colors and different depths are presented on the formed anti-counterfeitinglabel at the same time, the structure characteristics are three-dimensional, unique and non-reproducible, the dynamic color change effect can be presented along with the change of light, and therefore, the anti-counterfeiting grade is improved.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeit labels, in particular to a tamper-evident anti-counterfeit label and a manufacturing method thereof. Background technique [0002] The bottom label is also called VOID label. It is a self-adhesive material with a film as the base material. After it is pasted, it will leave a complete VOID or fixed information such as "unsealed" and "unsealed". The surface of the object can achieve the purpose of anti-tampering and anti-transfer. The existing peel-off bottom label has the advantages of anti-uncovering and anti-transfer, such as the utility model patent with the application number 2013204173975 and the name "a kind of anti-tear type positioning anti-counterfeiting label with double-layer holographic laser image", application number It is a utility model patent of 2017200522138 named "a two-color holographic laser anti-tear mark". However, the anti-counterfeiting labels disclosed in the ab...
