Description

Technical Field

[0001] This utility model relates to the field of corrugated paper technology, and in particular to an environmentally friendly corrugated paper with a double corrugated core. 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. According to the size of the corrugations, it is divided into five types: A, B, C, E, and F. Corrugated paper has been invented and used for more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. More than 80% of corrugated paper can be recycled. Corrugated paper can be used for food or digital product packaging. It is relatively environmentally friendly and widely used. Type A and Type B corrugated paper are generally used as outer packaging boxes for transportation. Beer boxes are generally made of Type B flute. Type E flute is mostly used for single-piece packaging boxes with certain aesthetic requirements and for holding appropriate weight of contents. Type F and Type G corrugated paper are collectively called micro-corrugated paper. It is an extremely thin type of corrugated paper and is used as disposable packaging containers for food such as hamburgers and cream-filled pastries, or as packaging for micro electronic products such as digital cameras and portable stereo systems, as well as refrigerated goods.

[0003] However, ordinary corrugated paper is easily damaged after one use during long-distance transportation due to insufficient support, and cannot be reused. A structure that can strengthen the support is needed to improve the service life of corrugated paper and achieve the effect of multiple environmentally friendly uses. Therefore, it is necessary to design an environmentally friendly corrugated paper with a double corrugated core. Utility Model Content

[0004] The main purpose of this utility model is to provide an environmentally friendly corrugated paper with a double corrugated core, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An environmentally friendly corrugated paper with a double corrugated core includes a center plate. An upper paper core is fixedly connected to the upper surface of the center plate, and an outer paper layer is fixedly connected to the upper surface of the upper paper core. A lower paper core is fixedly connected to the lower surface of the center plate. A bottom paper layer is fixedly connected to the lower surface of the lower paper core. An upper support plate is fixedly connected between the upper paper core and the outer paper layer, and a lower support plate is fixedly connected between the lower paper core and the bottom paper layer. A triangular groove is formed in the middle of both the upper and lower support plates.

[0007] In order to achieve uniform support, the environmentally friendly corrugated paper with a double corrugated core of this utility model has a number of upper support plates and lower support plates, which are arranged in an array.

[0008] In order to achieve the purpose of waterproofing, the environmentally friendly corrugated paper with a double corrugated core of this utility model has a waterproof layer fixedly connected to the upper surface of the outer paper.

[0009] In order to help avoid scratches, the environmentally friendly corrugated paper with a double corrugated core of this utility model has a scratch-resistant layer fixedly connected to the upper surface of the waterproof layer.

[0010] In order to achieve the purpose of providing a certain tensile structure, the outer layer of the environmentally friendly corrugated paper with a double corrugated core is provided with a deformation groove on its upper surface.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, the arrangement of a center plate, upper paper core, outer paper, lower paper core, bottom paper, upper support plate, lower support plate, and triangular grooves, along with the bonding of the upper and lower paper cores by the center plate to form a double-layer corrugated paper core structure, increases the thickness and improves the durability of the corrugated cardboard. The bottom and outer paper protect the bonding of the upper and lower paper cores by the center plate, preventing the upper and lower paper cores from supporting the packaging and affecting the most stable triangular structure formed by the wavy shape of the upper and lower paper cores or the recovery of deformation. The upper and lower support plates support the triangular shape formed by the wavy shape of the upper and lower paper cores, improving the support of the corrugated cardboard. The triangular grooves reduce the weight of the upper and lower support plates, thus reducing the weight of the cardboard, while providing the most stable triangular structure of the upper and lower support plates, ensuring the corrugated cardboard is durable and can be used multiple times, achieving environmentally friendly efficiency.

[0013] 2. In this utility model, by setting up an upper support plate, a lower support plate and a deformation groove, the upper support plate and the lower support plate can provide uniform force distribution and improve the range of support and protection. The deformation groove reduces the tensile strength of the outer surface of the outer paper, which can be used to package large items that need packaging protection. It can improve the tensile deformation ability of the outer paper and improve its applicability. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] like Figure 1-5 As shown, an environmentally friendly corrugated paper with a double corrugated core includes a center plate 1, an upper paper core 2 fixedly connected to the upper surface of the center plate 1, an outer paper 3 fixedly connected to the upper surface of the upper paper core 2, and a lower paper core 4 fixedly connected to the lower surface of the center plate 1.

[0023] In this embodiment, a bottom layer paper 5 is fixedly connected to the lower surface of the lower paper core 4, an upper support plate 6 is fixedly connected between the upper paper core 2 and the outer layer paper 3, and a lower support plate 7 is fixedly connected between the lower paper core 4 and the bottom layer paper 5. A triangular groove 8 is provided in the middle of both the upper support plate 6 and the lower support plate 7.

[0024] In practical use, the upper paper core 2 and the lower paper core 4 are bonded together by the center plate 1 to form a double-layer corrugated paper core structure, which increases the thickness and improves the durability of the corrugated cardboard. The bottom paper 5 and the outer paper 3 protect the upper paper core 2 and the lower paper core 4 bonded by the center plate 1, preventing the upper paper core 2 and the lower paper core 4 from supporting the packaged items and affecting the support or deformation recovery of the most stable triangular structure formed by the waves of the upper paper core 2 and the lower paper core 4. The upper support plate 6 and the lower support plate 7 can support the triangular shape formed by the waves of the upper paper core 2 and the lower paper core 4, improving the support of the corrugated cardboard. The triangular groove 8 can reduce the weight of the upper support plate 6 and the lower support plate 7, reduce the weight of the cardboard, and at the same time provide the most stable triangular structure of the upper support plate 6 and the lower support plate 7, which can ensure that the corrugated paper can be durable and reused many times, achieving environmentally friendly efficiency.

[0025] In this embodiment, there are several upper support plates 6 and lower support plates 7, and these several upper support plates 6 and lower support plates 7 are arranged in an array.

[0026] In practical use, the upper support plate 6 and the lower support plate 7 can provide uniform force distribution and improve the range of support and protection.

[0027] In this embodiment, a waterproof layer 9 is fixedly connected to the upper surface of the outer paper 3.

[0028] In practical use, the waterproof layer 9 can improve the waterproofness of the corrugated cardboard exterior, preventing the cardboard from being penetrated by water and causing a decrease in its structural integrity.

[0029] In this embodiment, a scratch-resistant layer 10 is fixedly connected to the upper surface of the waterproof layer 9.

[0030] In practical use, the scratch-resistant layer 10 can prevent external hard objects from damaging the cardboard, thus improving its protection.

[0031] In this embodiment, a deformation groove 11 is formed on the upper surface of the outer paper 3.

[0032] In practical use, the deformation groove 11 reduces the tensile strength of the outer surface of the outer paper 3, which can be used to package large items that need packaging protection. It can improve the tensile deformation ability of the outer paper 3 and improve its applicability.

[0033] Working Principle: In use, the upper paper core 2 and lower paper core 4 are bonded together by the center plate 1 to form a double-layer corrugated paper core structure, increasing the thickness and improving the durability of the corrugated cardboard. The bottom layer paper 5 and the outer layer paper 3 protect the upper paper core 2 and lower paper core 4 bonded by the center plate 1, preventing the upper paper core 2 and lower paper core 4 from supporting the packaged items and affecting the support or deformation recovery of the most stable triangular structure formed by the corrugations of the upper paper core 2 and lower paper core 4. The upper support plate 6 and lower support plate 7 can support the triangular shape formed by the corrugations of the upper paper core 2 and lower paper core 4, improving the support of the corrugated cardboard. The triangular groove 8 can reduce the weight of the upper support plate 6 and lower support plate 7. The design reduces the weight of the cardboard while providing the most stable triangular structure of the upper support plate 6 and the lower support plate 7, ensuring the corrugated cardboard is durable and can be used multiple times in an environmentally friendly manner. The upper support plate 6 and the lower support plate 7 provide uniform stress distribution, increasing the range of support and protection. The waterproof layer 9 improves the waterproofness of the corrugated cardboard exterior, preventing water penetration that could reduce its support. The scratch-resistant layer 10 prevents damage to the cardboard from hard external objects, improving its protective properties. The deformation groove 11 reduces the tensile strength of the outer surface of the outer paper 3, allowing for the packaging of large items requiring protection. It also improves the tensile and deformation capabilities of the outer paper 3, enhancing its applicability.
