Description

Technical Field

[0001] The invention relates to the technical field of anti-counterfeiting technology, and in particular to an anti-counterfeiting technology and application materials. Background Art

[0002] Anti-counterfeiting technology refers to the use of specific technical means to add difficult-to-copy or imitate marks to goods or documents in order to prevent forgery, imitation and fraud, so that consumers or relevant institutions can easily identify the authenticity. These technologies usually involve physics, chemistry, optics, electronics and other fields, and are aimed at protecting brand reputation, maintaining market order and safeguarding consumer rights.

[0003] As a high-value commodity, cigarettes often face the risk of counterfeiting and imitation. Counterfeit cigarettes not only infringe the intellectual property rights of the original manufacturers, but may also pose a threat to consumers' health because counterfeit products often use inferior raw materials and lack strict quality control. In addition, counterfeit cigarettes may also lead to tax loss and disrupt market order. Therefore, it is very necessary to use anti-counterfeiting technology on cigarette packaging boxes, which can help consumers identify authenticity and protect brand reputation, and also help the government crack down on counterfeit and shoddy products.

[0004] However, in general, although traditional anti-counterfeiting technologies, such as watermarks, special paper, anti-counterfeiting inks, etc., have played an anti-counterfeiting role to a certain extent, they also have some obvious shortcomings. For example, watermarks and special paper can be easily copied by high-imitation technology, and the formula of anti-counterfeiting inks may also be cracked. In addition, the verification process of traditional anti-counterfeiting technology is often more complicated, and consumers are required to have certain identification knowledge, which increases the difficulty of use for consumers. At the same time, once the traditional anti-counterfeiting technology is cracked, its anti-counterfeiting effect will be greatly reduced, and new anti-counterfeiting means will need to be replaced.

[0005] Based on this, the present invention provides an anti-counterfeiting process and application materials to solve the above-mentioned technical problems. Summary of the invention

[0091] In order to explore the influence of the parameter changes of the enhanced anti-counterfeiting layer 32 on the anti-counterfeiting effect, compared with Example 1, this comparative example only changes the proportion of the temperature-variable micro-shrinkage composite ink to 3%, in which the temperature-variable pigment and the micro-printing ink each account for 1.5%, and the other parameters remain unchanged.

[0092] Comparative Example 3

[0093] In order to explore the influence of the changes in the composite parameters of the colored polyester fiber holographic film on the anti-counterfeiting effect, compared with Example 1, this comparative example only changed the laminating temperature of the laminating machine to 105°C, and the other parameters remained unchanged.

[0098] 3. Experiment

[0099] The effects of the anti-counterfeiting packaging materials for cigarettes prepared in the above embodiments and comparative examples 1, 2, 3, 4, and 5 were verified, and the experimental steps were as follows:

[0100] a. Sample preparation: According to the parameter settings of the embodiments and comparative examples 1-5, samples of cigarette anti-counterfeiting packaging materials were prepared respectively, ensuring that during the preparation process of each sample, except for the change parameters, other parameters remained consistent;

[0101] b. Anti-counterfeiting effect test: b1. Fluorescence anti-counterfeiting test: Use ultraviolet light to illuminate the sample and observe the fluorescent effect of the double fluorescent composite pigment;

[0102] b2. Temperature change anti-counterfeiting test: place the sample in different temperature environments and observe the color change of the temperature change pigment;

[0103] b3. Micro-printing anti-counterfeiting test: observe the printing effect of micro-printing ink through a microscope;

[0104] b4. Holographic anti-counterfeiting test: observe the holographic effect of colored polyester fiber holographic film and BOPP laser holographic shrink film 4;

[0105] b5. Digital anti-counterfeiting test: Use a QR code scanner to scan the digital anti-counterfeiting layer 6 to verify the readability and anti-counterfeiting information of the QR code;

[0107] c.

[0108] Table 1 Cigarette anti-counterfeiting packaging material experiment and parameter table

[0109]

[0110]

[0111] 4. Conclusion Analysis

[0112] Based on the experimental data in the table, it can be seen that the anti-counterfeiting effect score of the embodiment is the highest, indicating that its parameter combination performs well in fluorescent anti-counterfeiting, temperature-change anti-counterfeiting, micro-anti-counterfeiting, holographic anti-counterfeiting and digital anti-counterfeiting. The physical property scores of all samples are high, indicating that the coating of the protective layer 5 is effective. However, due to the reduced coating speed of the comparative example 5, the uniformity of the protective layer 5 is slightly poor, and the physical property score is slightly low;

[0113] Therefore, the change in the ratio of the invisible fluorescent pigment and the ultraviolet sensitive pigment in the dual fluorescent composite pigment in Example 1 of the present invention has a certain influence on the anti-counterfeiting effect, but is not as superior as the combination of the embodiments. The reduction in the ratio of the temperature-variable miniature composite ink in Example 2 will significantly reduce the anti-counterfeiting effect. The fine-tuning of the lamination temperature in Example 3 and the heating temperature in Example 4 has a slight effect on the holographic anti-counterfeiting effect, but does not affect the overall anti-counterfeiting performance. The change in the coating speed in Example 5 mainly affects the uniformity and physical properties of the protective layer 5, and has little effect on the anti-counterfeiting effect.

[0114] In summary, the parameter combination in the embodiment performs best in terms of anti-counterfeiting effect and physical properties, and is a preferred solution for anti-counterfeiting packaging materials for cigarettes.

[0115] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
