Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, specifically to a high-strength corrugated cardboard. Background Technology

[0002] Corrugated cardboard is a commonly used packaging material, widely used in various industries due to its strength, light weight, and good compression resistance. Corrugated cardboard consists of at least three layers of paper: an outer layer, an inner layer, and a corrugated core.

[0003] Existing corrugated cardboard mainly consists of an outer paper layer, an inner paper layer, and a corrugated core board installed between the outer and inner paper layers. Although this type of corrugated cardboard can meet the packaging requirements of products, it relies solely on the corrugated core board to support the outer and inner paper layers, resulting in poor overall structural strength and making it prone to breakage and damage when subjected to accidental external impacts. Utility Model Content

[0004] (a) Technical problems to be solved The technical problem to be solved by this utility model is to provide a high-strength corrugated cardboard that can avoid breakage and damage from accidental impacts from external objects, in light of the current state of the technology.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a high-strength corrugated cardboard, including an outer corrugated paper layer, an inner corrugated paper layer below the outer corrugated paper layer, and a corrugated core board installed between the inner corrugated paper layer and the outer corrugated paper layer. A second reinforcing component is provided on the upper side of the corrugated core board, the second reinforcing component including a second support strip and a second edge sealing plate. A first reinforcing component is provided on the lower side of the corrugated core board, the first reinforcing component including a first support strip and a first edge sealing plate.

[0006] Furthermore, both the outer corrugated paper layer and the inner corrugated paper layer are bonded to the corrugated paper core board, and both the outer corrugated paper layer and the inner corrugated paper layer have their own waterproof membrane on their surfaces.

[0007] Furthermore, the corrugated paper core board has a wavy plate structure and is made of corrugated paper material.

[0008] Furthermore, the first support strip is bonded to the first edge sealing plate, and the shape of the first support strip matches the cavity shape on the lower side of the corrugated paper core board.

[0009] Furthermore, the second support strip is bonded to the second edge sealing plate, and the shape of the second support strip matches the shape of the cavity on the upper side of the corrugated paper core board.

[0010] Furthermore, the outer corrugated paper layer and the inner corrugated paper layer are provided with grooves on both sides that reliably fit with the first and second edge sealing plates.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: This invention utilizes a reinforcing component two, consisting of a second support strip and a second edge sealing plate, installed on the upper side of the corrugated paper core board, and a reinforcing component one, consisting of a first support strip and a first edge sealing plate, installed on the lower side of the corrugated paper core board. Under the action of the first and second reinforcing components, the overall structural strength of the corrugated cardboard is increased, avoiding the disadvantage of the corrugated cardboard being easily broken and damaged by accidental impacts from external objects during use, thus extending the service life of the corrugated cardboard.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] like Figures 1-2 As shown, a high-strength corrugated cardboard in this embodiment includes an outer corrugated paper layer 1, an inner corrugated paper layer 4 below the outer corrugated paper layer 1, and a corrugated core board 2 installed between the inner corrugated paper layer 4 and the outer corrugated paper layer 1. A second reinforcing component 5 is provided on the upper side of the corrugated core board 2, which includes a second support strip 501 and a second edge sealing plate 502. A first reinforcing component 3 is provided on the lower side of the corrugated core board 2, which includes a first support strip 301 and an first edge sealing plate 302. Under the action of the first reinforcing component 3 and the second reinforcing component 5 on the lower side of the corrugated core board 2, the overall structural strength of the corrugated cardboard is increased, avoiding the disadvantage that the corrugated cardboard is easily broken and damaged by accidental impact from external objects during use.

[0016] like Figures 1-2As shown, in this embodiment, both the outer corrugated paper layer 1 and the inner corrugated paper layer 4 are bonded to the corrugated core board 2. Both the outer corrugated paper layer 1 and the inner corrugated paper layer 4 have their own waterproof membranes. The design of these waterproof membranes ensures the waterproof performance of the corrugated cardboard during use. The corrugated core board 2 has a wavy, plate-like structure and is made of corrugated paper. The corrugated core board 2 is recyclable and environmentally friendly. Support strip 301 is bonded to the edge sealing plate 302. The shape of support strip 301 matches the shape of the cavity on the lower side of the corrugated core board 2. Inserted into the cavity on the upper side of the corrugated paper core board 2, the structural strength of the upper side of the corrugated paper core board 2 is increased. The second support strip 501 is bonded to the second edge sealing plate 502. The shape of the second support strip 501 matches the shape of the cavity on the upper side of the corrugated paper core board 2. The second support strip 501 is inserted into the cavity on the lower side of the corrugated paper core board 2, thereby increasing the structural strength of the lower side of the corrugated paper core board 2. The outer corrugated paper layer 1 and the inner corrugated paper layer 4 are provided with grooves on both sides that can reliably fit the first edge sealing plate 302 and the second edge sealing plate 502. The first edge sealing plate 302 can provide an installation base for the first support strip 301, and the second edge sealing plate 502 can provide an installation base for the second support strip 501.

[0017] The specific implementation process of this embodiment is as follows: When in use, first install reinforcing component 3 and reinforcing component 5 on both sides of the corrugated paper core board 2, and then simply glue the edge sealing plate 302 and edge sealing plate 502 to the corrugated cardboard as a whole, so that the corrugated cardboard can be put into use. During use, under the action of reinforcing component 3 and reinforcing component 5, the overall structural strength of the corrugated cardboard is increased, avoiding the disadvantage that the corrugated cardboard is easily broken and damaged by accidental impact from external objects, thus making the service life of the corrugated cardboard longer.

[0018] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
