Description

Technical Field

[0001] The utility model relates to the technical field of grey board paper, in particular to a novel multi-layer composite grey board paper. Background Art

[0002] Gray cardboard is made from recycled waste paper. The product is divided into single gray, double gray, and full gray, and is an environmentally friendly packaging material. The main uses of the product: packaging boxes, advertising boards, folders, photo frame backboards, bags, hardcover books, storage boxes, samples, lining boards, partitions, etc.

[0003] At present, China Patent No.: CN202222163403.0 discloses a composite high-gloss gray board paper, including a pulp layer, a kraft paper layer fixedly connected to the top of the pulp layer, a waterproof layer fixedly connected to the top of the kraft paper layer, a pressure-resistant layer fixedly connected to the bottom of the pulp layer, a tensile layer fixedly connected to the bottom of the pressure-resistant layer, an inner layer arranged at the bottom of the tensile layer, a high-gloss layer fixedly connected to the bottom of the inner layer and the top of the waterproof layer, and the tensile fiber is made of spandex fiber. The utility model increases the strength of the pulp layer by setting a fixed layer and tensile fibers, and the kraft paper layer and the waterproof layer provide waterproof protection for the pulp layer to prevent the pulp layer from absorbing water and becoming moldy, thereby solving the problem that the existing gray board paper has poor waterproofness, and when it encounters water or the humidity in the air is high, it is easy to absorb water, resulting in the phenomenon of softening and deformation of the gray board paper, and in severe cases, the phenomenon of mold and aging will occur, which reduces the service life of the gray board paper. However, in the actual use process of the prior art, there are still problems that the gray board paper is gray when used for outer packaging, the aesthetics is insufficient, and the outer packaging pattern is easy to wear. Utility Model Content

[0004] Therefore, in view of the above problems, the utility model proposes a novel multi-layer composite grey board paper, which solves the technical problems in the prior art that the grey board paper is grey when used for outer packaging, lacks aesthetics, and the outer packaging pattern is easily worn out during actual use.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a novel multi-layer composite grey board paper, whose structure includes a bottom layer, a middle supporting layer, a middle layer, a painted and printed layer, and a wear-resistant coating. The middle supporting layer is arranged above the bottom layer, the middle layer is arranged above the middle supporting layer, the painted and printed layer is arranged above the middle layer, and the wear-resistant coating is arranged above the painted and printed layer. The bottom layer, the middle supporting layer, and the middle layer are bonded and fixed in sequence.

[0006] Furthermore, the bottom layer and the middle layer are grey board paper layers, and the total weight of the bottom layer and the middle layer is 200-400 grams.

[0007] Furthermore, the middle supporting layer is a 1-2 layer unidirectional bamboo fiber composite structure.

[0008] Furthermore, the middle supporting layer has a gram weight of 50-100 grams.

[0009] Furthermore, the painted printing layer is made of waterproof printing ink.

[0010] Furthermore, the wear-resistant coating is a wear-resistant ceramic coating layer with a thickness of 100-500um.

[0011] By adopting the above-mentioned technical scheme, the beneficial effect of the utility model is as follows: the multi-layer composite gray board paper improves the existing technology in actual use, in which the gray board paper is gray when used for outer packaging, the aesthetics is insufficient, and the outer packaging pattern is easily worn. By setting a painted printing layer, a layer of base color is printed first, and then the pattern is added, the packaging produced by this scheme can be made more beautiful. The wear-resistant layer is set to effectively avoid the wear of the pattern during transportation and movement, thereby improving the aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0015] refer to Figure 1 The present embodiment provides a novel multi-layer composite grey board paper, whose structure includes a bottom layer 1, a middle supporting layer 2, a middle layer 3, a painted printing layer 4, and a wear-resistant coating 5. The middle supporting layer 2 is arranged above the bottom layer 1, the middle layer 3 is arranged above the middle supporting layer 2, the painted printing layer 4 is arranged above the middle layer 3, and the wear-resistant coating 5 is arranged above the painted printing layer 4. The bottom layer 1, the middle supporting layer 2, and the middle layer 3 are bonded and fixed in sequence.

[0016] The bottom layer 1 and the middle layer 3 are grey board paper layers, and the total weight of the bottom layer 1 and the middle layer 3 is 200-400 grams.

[0017] The middle supporting layer 2 is a 1-2 layer unidirectional bamboo fiber composite structure.

[0018] The middle supporting layer 2 has a gram weight of 50-100 grams.

[0019] The painted printing layer 4 is made of waterproof printing ink.

[0020] The wear-resistant coating 5 is a wear-resistant ceramic coating layer with a thickness of 100-500 um.

[0021] The multi-layer composite grey board paper improves the existing technology in actual use, in which the grey board paper is grey when used for outer packaging, the aesthetics is insufficient, and the outer packaging pattern is easily worn. By setting a painted printing layer 4, a layer of base color is printed first and then the pattern is added during printing, so that the packaging produced by this scheme can be more aesthetically pleasing. Setting a wear-resistant layer can effectively prevent the pattern from being worn during transportation and movement, thereby improving the aesthetics.
