Description

Technical Field

[0001] The utility model relates to the field of corrugated paperboards, in particular to a corrugated paperboard with high bonding strength. Background Art

[0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and a layer of containerboard (also called boxboard) bonded together. It has good elasticity and extensibility and is mainly used to make cartons, cardboard sandwiches and other packaging materials for fragile goods. It mainly uses traditional straw pulp and waste paper through pulping to make raw cardboard similar to yellow cardboard, which is then mechanically processed and rolled into a corrugated shape, and then sodium silicate and other adhesives are used on its surface to bond the containerboard.

[0003] Most of the current corrugated cardboards are made by pasting a layer of wavy paper core between two cardboards. However, the strength of the corrugated cardboard is relatively low. When it is poked by an object, it is easy to be punctured, causing damage to the corrugated box and affecting the quality of the product. Therefore, it is necessary to design a high-strength corrugated cardboard. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a corrugated cardboard with high bonding strength to solve the technical problem that the strength of the corrugated cardboard is low and it is easy to be punctured when it encounters an object, causing damage to the corrugated cardboard box and affecting product quality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a corrugated paperboard with high bonding strength, comprising a corrugated paperboard body, wherein the corrugated paperboard body is composed of an upper paperboard, a paper core board and a lower paperboard, the inner side of the upper paperboard is glued with a first gauze by strong glue, the inner side of the lower paperboard is glued with a second gauze by strong glue, and the paper core board is located between the upper paperboard and the lower paperboard.

[0006] By adopting the above technical solution, the overall structural strength of the corrugated cardboard is increased. The mesh structure of the plastic mesh helps to disperse the force, so that the corrugated cardboard can bear the pressure more evenly when subjected to external force, reducing the risk of local damage. The use of strong glue ensures a strong bond between the mesh and the cardboard, which can prevent the corrugated cardboard from delaminating during use, thereby improving its tear resistance and durability.

[0007] Furthermore, the first gauze and the second gauze are made of plastic material, and the first gauze and the second gauze have the same specifications.

[0008] By adopting the above technical solution, the gauze and the second gauze have the same specifications, which ensures the standardization and consistency of the corrugated board during the production process and helps to improve production efficiency and quality control.

[0009] Furthermore, strong glue is applied between the upper cardboard, the paper core board and the lower cardboard, and the upper cardboard, the paper core board and the lower cardboard are fixed by bonding.

[0010] By adopting the above technical solution, the use of strong glue ensures the firm bonding between the layers of the corrugated cardboard, thereby significantly improving the overall structural strength of the corrugated cardboard, enabling it to withstand greater pressure and impact.

[0011] Furthermore, the outer surfaces of the upper paperboard and the lower paperboard are smooth, and the upper paperboard and the lower paperboard are parallel to each other.

[0012] By adopting the above technical solution, the smooth outer surface provides a more beautiful appearance, which is especially important for products with high requirements for packaging appearance. It can enhance the overall image of the product. The smooth surface is more suitable for high-quality printing, making the graphic information on the packaging clearer and more vivid, which is helpful for brand communication and product marketing.

[0013] Furthermore, the paper core board is wavy, and a cavity is formed between the paper core board and the upper paperboard and the lower paperboard, and a sponge rod is arranged in the cavity.

[0014] By adopting the above technical solution, the cavity structure formed by the corrugated paper core board and the upper and lower paperboards, as well as the sponge rod in the cavity, together provide excellent cushioning performance. This structure can absorb and disperse external impacts and protect the items in the package from damage.

[0015] Furthermore, a plurality of sponge rods are provided, and the length of the sponge rods is the same as the length of the corrugated paper body.

[0016] By adopting the above technical solution and arranging a sponge rod in the cavity, additional strength and protection can be provided without significantly increasing the weight of the material, thereby making the use of materials more economical and efficient.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] 1. The utility model sets a first gauze and a second gauze, wherein the first gauze is pasted on the upper cardboard and the second gauze is pasted on the lower cardboard. The first gauze and the second gauze are both made of plastic. The mesh structure is pasted on the cardboard, which can differentiate the force applied to the cardboard, so that the cardboard is evenly stressed, and the strength of the cardboard is enhanced to a certain extent, thereby preventing the cardboard from being punctured.

[0019] 2. The utility model inserts a sponge rod into the cavity of the paper core board. The sponge rod is light in weight, low in cost, and high in production efficiency. The sponge rod is inserted into the pores between the paper core board and the upper and lower paperboards to enhance the pressure resistance of the corrugated paperboard, prevent the paperboard from being broken due to strong pressure, and improve the quality of the paperboard.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] Embodiment 1:

[0027] A high bond strength corrugated board, such as Figure 1-Figure 3 As shown, the corrugated paper body 1 is composed of an upper paperboard 2, a paper core board 4 and a lower paperboard 6. The inner side of the upper paperboard 2 is attached with a first gauze 3 by strong glue, and the inner side of the lower paperboard 6 is attached with a second gauze 5 by strong glue. The paper core board 4 is located between the upper paperboard 2 and the lower paperboard 6, which increases the overall structural strength of the corrugated paperboard. The mesh structure of the plastic gauze helps to disperse the force, so that the corrugated paperboard can bear the pressure more evenly when subjected to external force, reducing the risk of local damage. The use of strong glue ensures the firm adhesion between the gauze and the paperboard, which can prevent the corrugated paperboard from delaminating during use, thereby improving the breakage resistance and durability. The cavity structure formed between the middle paper core board of the corrugated paperboard and the upper and lower paperboards, combined with the inserted sponge rod, provides better cushioning performance, protecting the items in the package from impact and pressure damage. Due to the addition of the gauze material, this corrugated paperboard may have better adaptability and can maintain its performance under different environmental conditions, for example, it is more durable than ordinary corrugated paperboard in a humid environment.

[0028] See also Figure 2 and Figure 3The first gauze 3 and the second gauze 5 are made of plastic material, and the specifications of the first gauze 3 and the second gauze 5 are the same, which ensures the standardization and consistency of the corrugated cardboard in the production process, helps to improve production efficiency and quality control, and the plastic gauze has better tear resistance and durability than paper material, and can provide stronger protection, especially against impact and pressure during transportation.

[0029] See also Figure 2 Strong glue is applied between the upper cardboard 2, the paper core board 4 and the lower cardboard 6, and the upper cardboard 2, the paper core board 4 and the lower cardboard 6 are fixed by bonding. The use of strong glue ensures the firm bonding between the layers of the corrugated cardboard, thereby significantly improving the overall structural strength of the corrugated cardboard, enabling it to withstand greater pressure and impact. The good bonding effect improves the durability of the corrugated cardboard, extends its service life, reduces the frequency of replacement due to damage, and thus reduces long-term costs. The corrugated cardboard is made of recyclable paper material, combined with environmentally friendly strong glue, the environmental performance of the entire packaging material is improved, and it meets the requirements of sustainable development.

[0030] See also Figure 1 The outer surfaces of the upper cardboard 2 and the lower cardboard 6 are smooth, and the upper cardboard 2 and the lower cardboard 6 are parallel to each other. The smooth outer surface provides a more beautiful appearance, which is particularly important for products with high requirements for packaging appearance, and can enhance the overall image of the product.
