[0021] See also Figure 1-4The utility model provides a new type of laminated paper which is not easily deformed by pulling, including a laminated paper body 4, the laminated paper body 4 includes a base paper layer 1, and the surface of the base paper layer 1 is covered with a coating layer 2, and the bottom surface of the base paper layer 1 is covered with a hot stamping layer 3, the base paper layer 1 includes a first base paper layer 11, and the first base paper layer 11 is covered on the surface of a tensile resistance layer 12, and the bottom of the tensile resistance layer 12 is covered with a second base paper layer 13, and the paper fiber particles 112 in the first base paper layer 11 are mixed with mixed polymer particles 111; the base paper layer 1, the coating layer 2 and the hot stamping layer 3 are combined together to form a layered arrangement.

[0022] Working principle: The thickness of the coating layer 2 and the hot stamping layer 3 are both 0.1 mm, and the coating layer 2, the hot stamping layer 3, the polymer particles 111 and the anti-tear layer 12 are combined together to form the anti-tear structure of the coated paper;

[0023] The two sides of the laminated paper body 4 are respectively covered with a laminated layer 2 and a hot stamping layer 3 to increase the strength and durability of the paper;

[0024] A layer of anti-tear layer 12 is sandwiched in the laminated paper body 4. The anti-tear layer 12 is a thin metal mesh, which further improves the flexibility, strength and anti-tear performance of the laminated paper body 4.

[0025] Mixing polymer particles 111 in paper fiber particles 112 used for processing the laminated paper body 4 has the following three effects:

[0026] 1. Increase the bonding force between fibers; make the fibers less likely to separate when the paper is subjected to tension, thereby improving the ability to resist pulling;

[0027] 2. The polymer particles 111 can make the fibers of the paper more flexible and better able to resist stretching and deformation. This helps to improve the tear resistance of the paper, making it more difficult to tear;

[0028] 3. The polymer particles 111 can form a network structure in the paper, similar to a "fiber net"; this network structure can enhance the overall strength of the paper, making it more resilient when subjected to tension.

[0029] As a preferred embodiment, the thickness of the laminated paper body 4 is 0.75 mm, and the thickness of the laminating layer 2 and the hot stamping layer 3 on the laminated paper body 4 are consistent.

At the same time, the anti-tear layer 12 is clamped and fixed between the first base paper layer 11 and the second base paper layer 13.

[0031] The anti-tear layer 12 is a thin metal mesh. When the laminated paper body 4 is subjected to stress, the anti-tear layer 12 improves the flexibility, strength and anti-tear performance of the laminated paper body 4, making it less likely to tear or deform.

[0032] As a preferred implementation, the anti-tear layer 12 is a metal mesh, and a plurality of groups of regular hexagonal anti-tear mesh holes are evenly arranged inside the anti-tear layer 12. The thickness of the anti-tear layer 12 is 0.1 mm.

[0033] The thickness of the coating layer 2 and the hot stamping layer 3 are both 0.1 mm, and the coating layer 2, the hot stamping layer 3, the polymer particles 111 and the anti-tear layer 12 are combined together to form the anti-tear structure of the coated paper.
