AI Technical Summary
The anti-counterfeiting patterns on existing anti-counterfeiting cards are prone to fading, discoloration, or wear after prolonged use, thus losing their anti-counterfeiting function.
The cardboard features a multi-layered design, including a core layer, a bottom layer, a connecting layer, an anti-counterfeiting layer, and a top layer. The anti-counterfeiting layer has a high-definition watermark, and the combination of different materials and thicknesses enhances the cardboard's durability and waterproof performance.
It enhances the protection of the anti-counterfeiting watermark, preventing it from peeling off and fading, and ensuring that the watermark remains clearly visible even after the cardboard is worn or contaminated.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard technology, and in particular to a cardboard with anti-counterfeiting high-definition watermark. Background Technology
[0002] With social development, technological progress, more detailed social division of labor, and rising consumer demands, the printing and packaging industry has developed rapidly, with paper packaging being particularly prominent. Cardboard, as a common paper packaging material, is widely used in the packaging of tobacco, alcohol, cosmetics, electronic products, and more.
[0003] In these packaging applications, anti-counterfeiting labels are usually required. However, in the existing technology, the anti-counterfeiting patterns on anti-counterfeiting cardboard are prone to fading, discoloration, or wear after long-term use, thus losing their anti-counterfeiting function. Therefore, a cardboard with anti-counterfeiting high-definition watermark is proposed. Utility Model Content
[0004] In view of the problem that the anti-counterfeiting patterns on the aforementioned anti-counterfeiting cardboard are prone to fading, discoloration, or wear after long-term use, thus losing their anti-counterfeiting function, this utility model is proposed.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cardboard with anti-counterfeiting high-definition watermark, comprising a core layer, a lower paper layer bonded to the lower surface of the core layer, a connecting layer bonded to the upper surface of the core layer, an anti-counterfeiting layer bonded to the upper surface of the connecting layer, an upper paper layer bonded to the upper surface of the anti-counterfeiting layer, and a high-definition watermark on the anti-counterfeiting layer.
[0006] Preferably, the two sides of the lower paper layer are made of paper with different smoothness.
[0007] Preferably, the thickness of the paper core layer is 0.1-0.5 mm.
[0008] Preferably, the thickness of the lower paper layer is 0.01-0.05 mm.
[0009] Preferably, the thickness of the lower paper layer is 0.05-0.1 mm.
[0010] The beneficial effects of this utility model are:
[0011] 1. The anti-counterfeiting layer is set between the top paper layer and the core paper layer, which increases the protection of the anti-counterfeiting layer, and in turn increases the protection of the anti-counterfeiting watermark, making the anti-counterfeiting watermark more difficult to peel off and fade or change color.
[0012] 2. The paper core layer is thickened to ensure that the anti-counterfeiting watermark remains clear even after the cardboard is folded or wet. Attached Figure Description
[0013] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Among them:

[0016] Explanation of reference numerals in the attached figures:
[0017] 1. Paper core layer; 2. Bottom paper layer; 3. Connecting layer; 4. Anti-counterfeiting layer; 5. Top paper layer. Detailed Implementation
[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0019] Reference Figure 1-2 This invention provides a paperboard with anti-counterfeiting high-definition watermark. The paperboard with anti-counterfeiting high-definition watermark includes a paper core layer 1, a lower paper layer 2 bonded to the lower surface of the paper core layer 1, a connecting layer 3 bonded to the upper surface of the paper core layer 1, an anti-counterfeiting layer 4 bonded to the upper surface of the connecting layer 3, an upper paper layer 5 bonded to the upper surface of the anti-counterfeiting layer 4, and a high-definition watermark on the anti-counterfeiting layer 4.
[0020] In some embodiments, the high-definition watermark is arranged horizontally and vertically;
[0021] In some embodiments, the high-definition watermark is arranged at a 0-180 degree angle to the horizontal direction of the cardstock.
[0022] The thickness of the core layer 1 is 0.1-0.5 mm. The thicker paper layer improves the strength, stability and support of the cardboard. The core layer 1 is made of wood pulp paper.
[0023] The two sides of the lower paper layer 2 are made of paper with different smoothness. The smooth side is located on the outside of the cardboard, and the rough side is bonded to the core layer 1.
[0024] Understandably, a smooth paper surface has better water resistance;
[0025] Furthermore, the thickness of the lower paper layer 2 is 0.01-0.05 mm, and the material is PVC (polyvinyl chloride) or whiteboard paper.
[0026] The upper paper layer 5 has rough paper surfaces on both sides, which allows it to adhere better to the anti-counterfeiting layer 4 and makes it easy to write on the cardstock. The upper paper layer 5 has a thickness of 0.01-0.05 mm and is made of fiber paper.
[0027] The connecting layer is 0.01-0.05 mm thick and is made of PVC (polyvinyl chloride) or whiteboard paper.
[0028] During use, the rough surface of the lower paper layer 2 is bonded to the paper core layer 1. The smooth paper surface facing outwards improves the waterproof performance of the cardboard. Then, the connecting layer 3 is bonded to the other side of the paper core layer. Next, the anti-counterfeiting layer 4 with the anti-counterfeiting high-definition watermark printed on it is bonded to the upper surface of the paper core layer. Finally, the upper paper layer 5 is bonded to the anti-counterfeiting layer 4. The anti-counterfeiting high-definition watermark can be seen through the upper paper layer 5. When the surface of the cardboard is worn or contaminated, the anti-counterfeiting high-definition watermark remains intact and clear because it is located on the anti-counterfeiting layer 4 between the upper paper layer 5 and the paper core layer 1.
[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
