Description

A corrugated paper with a cushioning structure Technical Field

[0001] This utility model belongs to the field of corrugated paper technology, specifically relating to a corrugated paper with a cushioning structure. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into single-wall and double-wall corrugated paperboard, and further classified into five types according to the size of the corrugations: A, B, C, E, and F. Corrugated paper has been invented and used for over a century. It boasts advantages such as low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. Over 80% of corrugated paper can be recycled. It is widely used for packaging food and digital products, is relatively environmentally friendly, and has a broad range of applications.

[0003] Existing corrugated paper mainly relies on internal corrugated paper for cushioning. When corrugated paper is impacted, the corrugated paper is prone to deformation or even breakage, leading to a decrease in the functionality of the corrugated paper and thus affecting the cushioning effect of the corrugated paper. Summary of the Invention

[0004] The purpose of this invention is to provide a corrugated paper with a cushioning structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrugated paper with a cushioning structure, comprising an outer paperboard and a cushioning mechanism, wherein there are two outer paperboards, the cushioning mechanism is disposed between the two outer paperboards, the cushioning mechanism includes a cushioning paperboard disposed between the two outer paperboards, a corrugated paper is fixedly connected between the cushioning paperboard and the outer paperboard, a support strip is fixedly connected to the side of the cushioning paperboard near the corrugated paper, the inside of the support strip is filled with a rubber cushioning rod, and a reinforcing layer is fixedly connected to the side of the corrugated paper near the outer paperboard.

[0006] In a preferred embodiment, both the outer paperboard and the cushioning paperboard are biodegradable paperboard.

[0007] In a preferred embodiment, the surface of the outer cardboard is provided with a PTFE waterproof layer.

[0008] In a preferred embodiment, the cushioning cardboard is filled with a polyurethane foam layer.

[0009] In a preferred embodiment, the reinforcing layer is a carbon fiber woven mesh.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This corrugated paper with a cushioning structure can cushion the corrugated paper through the cushioning mechanism. The setting of cushioning cardboard, corrugated paper and polyurethane foam layer gives the corrugated paper basic cushioning ability. The setting of support strips and rubber cushioning rods can provide cushioning support for the corrugated paper. When the corrugated paper is impacted, it is not easy for the corrugated paper to deform. The reinforcing layer can improve the structural strength of the corrugated paper, making it less likely to break. Thus, the functionality of the corrugated paper is guaranteed and the cushioning effect of the corrugated paper is improved.

[0012] This corrugated paper with a cushioning structure improves its environmental performance by using biodegradable cardboard and enhances its cushioning capacity by using a polyurethane foam layer as a cushioning material. Furthermore, polyurethane foam is an environmentally friendly material, further improving the overall environmental impact of the corrugated paper. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] Please refer to Figures 1-3. This utility model provides a corrugated paper with a cushioning structure, including an outer cardboard 1 and a cushioning mechanism 2. There are two outer cardboards 1, and the cushioning mechanism 2 is disposed between the two outer cardboards 1. The cushioning mechanism 2 can cushion the corrugated paper.

[0020] Specifically, the cushioning mechanism 2 includes a cushioning cardboard 21 disposed between two outer cardboard layers 1. Corrugated paper 22 is fixedly connected to the cushioning cardboard 21 and the outer cardboard layers 1. A support strip 23 is fixedly connected to the side of the cushioning cardboard 21 closest to the corrugated paper 22. A rubber cushioning rod 24 is filled inside the support strip 23. A reinforcing layer 25, which is a carbon fiber woven mesh, is fixedly connected to the side of the corrugated paper 22 closest to the outer cardboard layers 1. A polyurethane foam layer 26 is filled inside the cushioning cardboard 21. Through the arrangement of the cushioning cardboard 21, corrugated paper 22, and polyurethane foam layer 26, the corrugated paper possesses basic cushioning capabilities. The support strip 23 and rubber cushioning rod 24 provide cushioning support for the corrugated paper 22, preventing deformation when impacted. The reinforcing layer 25 enhances the structural strength of the corrugated paper 22, preventing breakage and ensuring its functionality, thus improving the cushioning effect on the corrugated paper.

[0021] Furthermore, both the outer cardboard 1 and the cushioning cardboard 21 are biodegradable cardboard. By using biodegradable cardboard, the environmental performance of corrugated paper can be improved.

[0022] Furthermore, a PTFE waterproof layer 11 is provided on the surface of the outer cardboard 1. The PTFE waterproof layer 11 can improve the waterproof effect of the corrugated paper surface.

[0023] The working principle and usage process of this utility model are as follows: First, the buffer mechanism 2 can buffer the corrugated paper. The arrangement of the buffer cardboard 21, the corrugated paper 22 and the polyurethane foam layer 26 enables the corrugated paper to have basic buffering ability. The arrangement of the support strip 23 and the rubber buffer rod 24 can provide buffering support for the corrugated paper 22. When the corrugated paper is impacted, the corrugated paper 22 is not easily deformed. The reinforcing layer 25 can improve the structural strength of the corrugated paper 22, making the corrugated paper 22 less prone to damage, thereby ensuring the functionality of the corrugated paper 22 and improving the buffering effect of the corrugated paper.
