Problems solved by technology

However, this kind of anti-counterfeiting mark is only suitable for ordinary products in daily life. For some high-end products, especially some products that still need to be forensic after the product is destroyed, these ordinary anti-counterfeiting marks do not have any advantages and cannot reach the goal at all. identification requirements in some special cases

Embodiment 1

[0021] The manufacturing method of the shape-memory anti-counterfeiting label with permanent memory information of the present invention comprises the following steps: extruding each component of the formula amount into a sheet material after mixing in an extruder, and putting the sheet material in Heat it on the heating machine to produce deformation, and then press the pattern or text on the sheet material to obtain a shape memory anti-counterfeiting substrate with permanent memory information. After the substrate is printed, glued, and die-cut, the information with permanent memory is obtained. Shape memory anti-counterfeiting mark. The extrusion temperature of the extruder is 190 degrees, and the screw speed is 350 r / min.

[0022] Among them, the polymer material is prepared from the following components in parts by mass:

[0023]

[0024] When identifying: Put the anti-counterfeit label in hot water above 70 degrees or use a lighter to grill the anti-counterfeit label...

Embodiment 2

[0026] Preparation method and identification method are as embodiment 1, and the polymer material of embodiment 2 consists of the following components in parts by mass

[0027] Prepared from:

Abstract

The invention relates to an anti-counterfeiting mark, in particular to a manufacturing method of a shape memory anti-counterfeiting mark with permanent memory information. The manufacturing method of the shape memory anti-counterfeiting mark with the permanent memory information comprises preparation of a high-molecular polymer material. The high-molecular polymer material is prepared by the following components, by weight, 100 parts of polylactic acid, 0.1-1 part of polycaprolactone, 0.1-1 part of deoxyribonucleic acid (DNA) printing ink, 0.01-0.2 part of antioxygen and 0.1-0.3 part of inorganic filler. The manufacturing method of the shape memory anti-counterfeiting mark is simple and easy to operate and easy to achieve. The anti-counterfeiting mark can distinguish the true from the false in duplex mode, can protect consumer benefit, guarantees manufacturer benefit and product reputation, and is particularly suitable for being applied to high-end products. In addition, polylactic acid and polycaprolactone are both biodegradable. The anti-counterfeiting mark is an environment-friendly anti-counterfeiting mark.

Description

technical field [0001] The invention relates to an anti-counterfeit mark, in particular to a method for making a shape-memory anti-counterfeit mark with permanent memory information. Background technique [0002] There are many kinds of anti-counterfeiting marks at present, most of which are paper anti-counterfeiting marks and laser anti-counterfeiting marks. The application of anti-counterfeiting marks not only protects the products of merchants, but also brings convenience to consumers in identifying the authenticity of products. [0003] With the development of economy and society, the use of anti-counterfeiting marks with shape memory function is becoming more and more extensive. Shape memory anti-counterfeiting marks are generally realized by utilizing the memory function of high molecular polymers. Put this kind of anti-counterfeit label in 100-degree hot water or use a lighter to grill the anti-counterfeit label, and the anti-counterfeit label will form a concave-co...
