Description

Technical Field

[0001] The utility model relates to the technical field of packaging paper, in particular to anti-counterfeiting packaging paper. Background Art

[0002] Cigarettes packed in hard boxes have ideal aroma preservation and moisture-proof effects due to the special structure of their packaging boxes, while cigarettes packed in soft boxes are far inferior to those packed in hard boxes in aroma preservation and moisture-proof effects, especially the aroma preservation and moisture-proof effects of unpacked soft box cigarettes are even worse. In order to solve the problem of poor aroma preservation and moisture-proof effects of soft box cigarettes, medium-to-high-end and low-end cigarettes are generally packed with multi-layer composite wrapping paper to enhance the aroma preservation and moisture-proof effects, but the patterns on the multi-layer composite wrapping paper cannot be effectively compared and displayed, the patterns are easy to imitate, and the anti-counterfeiting effect is poor.

[0003] After searching, the Chinese utility model patent with publication number CN219153937U is named as an environmentally friendly implicit anti-counterfeiting packaging paper, which can display hidden pictures and texts under strong light. However, this implicit anti-counterfeiting method has some potential problems. If consumers do not know that they need to observe the anti-counterfeiting effect under strong light, they will miss the key information for identifying the authenticity. Without clear guidance, consumers may only view the packaging paper in a conventional way, and thus fail to discover the hidden anti-counterfeiting marks or features. In view of this, an anti-counterfeiting packaging paper is designed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1-2 , an anti-counterfeiting packaging paper, comprising a base layer 1, an aluminum layer 2 is connected to the upper surface of the base layer 1, an anti-counterfeiting layer 3 is connected to the upper surface of the aluminum layer 2, a holographic laser layer 4 is connected to the upper surface of the anti-counterfeiting layer 3, a protective film layer 5 is connected to the upper surface of the holographic laser layer 4, and a printing layer 6 is connected to the upper surface of the protective film layer 5. Due to the use of multiple anti-counterfeiting technologies of the anti-counterfeiting layer 3 and the holographic laser layer 4, the anti-counterfeiting layer 3 adopts color changes and special textures, consumers can easily identify the authenticity without specific conditions, and the holographic laser layer 4 can maintain a stable display effect under a variety of light conditions. The cooperation of the anti-counterfeiting layer 3 and the holographic laser layer 4 can solve the problem of affecting the identification of the anti-counterfeiting effect due to insufficient ambient light.

[0025] The base layer 1 is one of moisture-proof paper, smooth paper or environmentally friendly paper. The base layer 1 is the base layer of the anti-counterfeiting wrapping paper, which provides the overall structural strength. If the anti-counterfeiting wrapping paper needs to be used in a humid environment, the base layer 1 is made of moisture-proof paper, which can effectively resist moisture erosion and prevent the anti-counterfeiting wrapping paper from deforming or degrading due to moisture absorption. In order to obtain better printing effect and anti-counterfeiting layer processing quality, the base layer 1 can choose paper with a smooth surface, which can provide a uniform printing surface, making the graphic information clearer and more accurate. Environmentally friendly paper can also be used as the base layer 1. Environmentally friendly paper is made of renewable resources, has a lower environmental impact, and meets the requirements of sustainable development.

[0026] The thickness of the aluminum layer 2 is 300 to 350 angstroms. The aluminum layer 2 is plated on the upper surface of the base layer 1 by a vacuum aluminum plating machine. Compared with the traditional aluminum foil with a thickness of 6 μm, the amount of aluminum used in the anti-counterfeiting packaging paper is about 1 / 200 of the traditional aluminum foil. Such a thin aluminum layer 2 can be quickly degraded and has a certain light transmittance.

[0027] The anti-counterfeiting layer 2 includes a variety of colors and patterns. The anti-counterfeiting layer 3 uses color changes and special textures, so that consumers can easily identify the authenticity without specific conditions, effectively preventing the packaging paper from being forged or tampered with, and protecting the legitimate rights and interests of consumers.

[0028] The anti-counterfeiting layer 2 is a magnetic coating, and the thickness of the magnetic coating is 0.6-1.5um. The coating process of the magnetic coating is as follows: 1.5kg of polyurethane resin is dissolved in acetone, and magnetic nano-silicon dioxide is added and stirred and dispersed for 2h. After uniform dispersion, 30g of aluminum oxide, 50g of sodium stearate, 10g of silicate, 50g of silicone oil and 10g of carbon black are added in sequence, and stirred for 1h, and then 0.2kg of toluene diisocyanate is added, and the magnetic coating is obtained after mixing and dispersing for 30min. The preparation process of magnetic nano-silica is as follows: 1. Add 100 mL of cooled boiling water into a three-necked flask, introduce nitrogen into the flask, add 2.7 g of FeCl3·6H2O and 3 g of FeCl2·4H2O into the water, stir and dissolve at 70°C, then add 30 mL of a 2.5 mol / L NaOH solution dropwise into the mixed solution, stir for 3 h until a black flocculent precipitate appears, and dry the solid at 50°C after magnetic separation to obtain a magnetic material; dissolve the magnetic material in anhydrous ethanol to prepare a 10 mg / mL magnetic fluid solution, take 12 mL of the magnetic fluid solution, 25 mL of ammonia water and 120 mL of anhydrous ethanol and stir evenly at 30°C, then slowly add 3 mL of tetraethyl orthosilicate and 120 mL of anhydrous ethanol, stir and react for 12 h, separate the product magnetically and dry it at 80°C, calcine the dried solid in a tubular furnace with N2 for 3 h to obtain a magnetic nano-silica material. The magnetic coating is evenly sprayed on the surface of the aluminum layer 2 by using an air spray coating method.

[0029] The holographic laser layer 4 uses laser holographic technology to create a three-dimensional image on the material. This image not only has a high visual impact, but also has a strong anti-counterfeiting performance. Holographic laser technology creates microscopic interference fringes on the anti-counterfeiting packaging paper. When light shines on these fringes, a unique diffraction effect will be produced, forming an image with depth and three-dimensionality. This image is difficult to copy, which improves the anti-counterfeiting effect.

[0030] The printing layer 6 includes a UV offset ink layer. The printing layer 6 is used to carry patterns, texts and brand logos on the anti-counterfeiting packaging paper. The UV offset ink layer can ensure clear and durable printing effects.

[0031] The upper surface of the printing layer 6 is connected with a first protective layer 7, which is a thermoplastic polyurethane elastomer rubber. Thermoplastic polyurethane elastomer rubber provides excellent protection for the printing layer 6 with its high strength, high toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance and other characteristics. The first protective layer 7 can effectively prevent the printing layer 6 from being damaged by the external environment, such as scratches, friction, chemical corrosion, etc., thereby extending the service life of the printing layer 6 and maintaining its good visual effect. Secondly, the transparency of the thermoplastic polyurethane elastomer rubber is good, which can keep the pattern and color of the printing layer 6 clearly visible without blocking or affecting it, which makes the appearance of the anti-counterfeiting packaging paper more beautiful, and also makes it convenient for consumers to view and identify the information on the product. At the same time, the elasticity and flexibility of the thermoplastic polyurethane elastomer rubber also enable the first protective layer 7 to adapt to products of different shapes and curves, ensuring a tight fit and not easy to fall off.

[0032] Embodiment 2:

[0033] See also Figure 3 This embodiment provides an anti-counterfeiting packaging paper. On the basis of the first embodiment, the following structure is added: the lower surface of the base layer 1 is connected to a second protective layer 8, and the second protective layer 8 provides additional protection for the base layer 1. During use, the anti-counterfeiting packaging paper will be affected by physical friction, chemical corrosion or environmental factors (such as humidity and temperature), which will cause damage to the base layer 1. The second protective layer 8 can effectively isolate these potential damage sources and maintain the integrity and stability of the base layer 1.

[0034] The second protective layer 8 is thermoplastic polyurethane elastomer rubber. Thermoplastic polyurethane elastomer rubber provides excellent physical protection for anti-counterfeiting packaging paper with its excellent wear resistance, ozone resistance, high hardness, high strength and good elasticity, and can effectively resist external physical friction, impact and stretching, ensuring that the anti-counterfeiting packaging paper remains intact during transportation, storage and use, and preventing the leakage or distortion of anti-counterfeiting information due to damage.

[0035] In summary, the anti-counterfeiting packaging paper adopts multiple anti-counterfeiting technologies of the anti-counterfeiting layer 3 and the holographic laser layer 4. The anti-counterfeiting layer 3 adopts color changes and special textures, so consumers can easily identify the authenticity without specific conditions, and the holographic laser layer 4 can maintain a stable display effect under various light conditions. The anti-counterfeiting layer 3 and the holographic laser layer 4 can solve the problem of the anti-counterfeiting effect recognition being affected by insufficient ambient light. The first protective layer 7 and the second protective layer 8 play the role of waterproof, moisture-proof and wear-resistant, which can extend the service life of the anti-counterfeiting packaging paper.
