[0026] See also Figure 1-5 The utility model provides a technical solution: a card that is not easy to wrinkle, including a card 1, the interior of the card 1 is divided into a first wear-resistant layer 2, a reinforcement layer 3, and a second wear-resistant layer 4, the opposite surfaces of the first wear-resistant layer 2 and the second wear-resistant layer 4 are fixedly connected to the two sides of the reinforcement layer 3, and the opposite surfaces of the first wear-resistant layer 2 and the second wear-resistant layer 4 are each provided with a cross groove 5, and the interiors of the two cross grooves 5 are both fixedly connected with a cross metal piece 6, which is made of copper thin sheet metal. By placing the cross metal piece 6 inside the card, the weight and thickness of the entire card can be increased, thereby enhancing the hardness and durability of the card, thereby improving the anti-wrinkle performance of the card on the side.

[0027] Furthermore, the first wear-resistant layer 2 and the second wear-resistant layer 4 are provided with two grid grooves 7 on the opposite sides, and the four grid grooves 7 are respectively located on the upper and lower sides of the corresponding cross groove 5. Two protrusions 11 are fixedly connected to both sides of the reinforcement layer 3. The outer surfaces of the four protrusions 11 are respectively fixedly connected to the inner walls of the corresponding grid grooves 7. The interior of the reinforcement layer 3 is divided into five layers, all of which are composite layers 12. Every two composite layers 12 are fixedly connected. The interior of the composite layer 12 is divided into PVC paper 8, blue core paper 9, and white kraft paper 10. The PVC paper 8 is close to the blue core paper 9. One side of the core paper 9 is fixedly connected to one side of the blue core paper 9, and the side of the blue core paper 9 away from the PVC paper 8 is fixedly connected to one side of the white kraft paper 10. Through the mutual connection between the grid groove 7 and the protrusion 11, the various parts of the card can be more closely combined together, thereby enhancing the integrity and unity of the card and improving the overall quality of the card. At the same time, the combination of the grid groove 7 and the protrusion 11 can make the card more sturdy and durable, because this structure increases the load-bearing capacity and bending strength of the card, which can effectively prevent the card from breaking, cracking and other problems during normal use.

[0028] Furthermore, the blue core paper 9 is a high-quality paper made of a composite material of virgin wood pulp and renewable resources, and has the advantages of good strength and durability. The PVC paper 8 is a plastic paper, and has the advantages of good hardness and durability. The white kraft paper 10 is an environmentally friendly material, and has the advantages of tough texture and not easy to tear or break. The white kraft paper 10 and the blue core paper 9 are arranged together in a certain order, and then placed in a laminating machine, and pressed into a layer using high temperature and high pressure. Then the PVC paper 8 is placed on the top, and a hot press is used to perform hot pressing again to combine the PVC paper 8 and the paper together, so that a composite layer 12 can be combined.

[0029] Furthermore, the combined composite layer 12 has good folding and bending resistance, and is not easy to wrinkle. The five composite layers 12 are fixedly connected together, which can make the reinforcement layer 3 have a strong hardness, so that the card is not easy to wrinkle and damage. The first wear-resistant layer 2 and the second wear-resistant layer 4 are both made of blue core paper material. The blue core paper material not only has good strength and durability advantages, but also has a thicker texture, which can play an anti-wrinkle role, so that the two sides of the card can prevent wrinkles to a certain extent, further improving the practicality of the card.
