Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard technology, and in particular relates to a high-cushioning environmentally friendly corrugated cardboard. Background Technology

[0002] In modern industrial production and commodity circulation, corrugated cardboard, as a common packaging and structural material, is widely used due to its advantages such as light weight and low cost. However, in terms of cushioning performance, traditional corrugated cardboard mostly uses a single corrugated structure, relying solely on the deformation of the corrugations to achieve a cushioning effect. When subjected to external impact, the cushioning capacity of this single structure is limited and cannot effectively resist large impact forces, easily leading to damage to the contents of the packaged items. Especially in scenarios with extremely high cushioning requirements, such as transporting fragile goods and precision electronic products, the protective effect of traditional corrugated cardboard falls far short of the needs. Utility Model Content

[0003] The purpose of this utility model is to provide a high-cushioning, environmentally friendly corrugated cardboard to address the aforementioned technical problems.

[0004] In view of this, the present invention provides a high-buffering environmentally friendly corrugated cardboard, wherein a corrugated paper layer is provided on the upper surface of the middle layer; The baseboard has a substrate layer on its upper surface of the corrugated paper layer; A buffer layer is provided on the upper surface of the substrate layer; The upper surface is provided with an upper surface layer; A support layer is provided on the lower surface of the intermediate layer; The lower surface layer is provided on the lower surface of the support layer.

[0005] In the above technical solution, the buffer layer further includes: Elastic pads: Several elastic pads are evenly distributed on the upper surface of the base plate; Tensioner plate: A tensioner plate is fixedly installed on the outer surface of the elastic pad.

[0006] In the above technical solution, the support layer further includes: Hexagonal support columns: Several hexagonal support columns are fixedly installed on the lower surface of the middle layer and are evenly arranged.

[0007] Furthermore, in the above technical solution, the hexagonal support column is filled with cushioning material.

[0008] In the above technical solution, the intermediate layer is further defined as a PVC plastic sheet.

[0009] In the above technical solution, the baseboard, the upper surface layer, and the lower surface layer are further defined as cardboard layers.

[0010] In the above technical solution, furthermore, a number of anti-slip pads are fixedly provided on the lower surface of the lower layer.

[0011] In the above technical solution, the upper surface layer, buffer layer, base board, corrugated paper layer, middle layer, support layer, lower surface layer and anti-slip pad are connected by adhesive bonding in sequence.

[0012] The beneficial effects of this utility model are as follows: 1. The elastic pad can absorb a large amount of impact energy through its own compression deformation, effectively reducing the impact of impact on internal items. The tension plate is fixed on the outer surface of the elastic pad, which can play a certain protective role, preventing the elastic pad from being worn or damaged during use. It can also limit the excessive deformation of the elastic pad through its own tension when the elastic pad deforms, ensuring that the elastic pad can quickly return to its original shape, thus ensuring the stability and durability of the cushioning performance.

[0013] 2. The support layer is mainly composed of hexagonal support columns, which are fixed to the lower surface of the intermediate layer. Several hexagonal support columns are evenly arranged to form a stable support structure. The hexagonal structure has excellent mechanical properties and can evenly distribute pressure.

[0014] 3. The middle layer is made of PVC plastic sheet. PVC plastic sheet has good structural stability and a certain degree of toughness. At the same time, its chemical properties are stable, and its impact on the environment is small during proper use and disposal, which meets environmental protection requirements.

Detailed Implementation

[0016] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0017] Example 1:

[0018] This embodiment provides a high-cushioning, environmentally friendly corrugated cardboard, comprising: Intermediate layer 1, with a corrugated paper layer 2 disposed on the upper surface of intermediate layer 1; The baseboard 3 has a substrate layer 3 on its upper surface of the corrugated paper layer 2; Buffer layer 4 is provided on the upper surface of substrate layer 3; Upper surface layer 5, the upper surface is provided with upper surface layer 5; Support layer 6 is provided on the lower surface of intermediate layer 1; The lower surface layer 7 is provided on the lower surface of the support layer 6.

[0019] As can be seen in this embodiment, the intermediate layer 1 is the core supporting foundation of the corrugated cardboard, providing reliable support for the entire corrugated cardboard. The corrugated paper layer 2 is placed on the upper surface of the intermediate layer 1. The corrugated paper layer 2 adopts a common corrugated structure. Through the special shape of the corrugations, it can deform when subjected to external forces, thereby initially absorbing and dispersing the impact force, providing basic cushioning performance for the corrugated cardboard. Furthermore, the corrugated paper itself is a recyclable and biodegradable material, which is beneficial to improving the overall environmental friendliness. The baseboard 3 is laid on the upper surface of the corrugated paper layer 2. On the one hand, it can be tightly bonded to the corrugated paper layer 2, enhancing the stability of the corrugated paper layer 2 structure. On the other hand, it provides a flat and stable installation foundation for the upper cushioning layer 4, ensuring that the cushioning layer 4 can function stably. The cushioning layer 4 is placed on the baseboard 3. The upper surface is a key structure for achieving high cushioning performance. The upper surface layer 5 covers the upper surface of the cushioning layer 4. As the upper surface of the corrugated cardboard, the upper surface layer 5 can protect the cushioning layer 4 from the direct impact of the external environment, such as preventing dust and moisture from entering the interior of the cushioning layer 4 and affecting its cushioning performance. At the same time, the surface of the upper surface layer 5 is flat, which facilitates subsequent processing such as printing and marking, meeting the appearance and functional requirements of different application scenarios. The support layer 6 is set on the lower surface of the middle layer 1, which can provide strong support and stability, effectively improving the overall load-bearing capacity of the corrugated cardboard. The lower surface layer 7 is laid on the lower surface of the support layer 6. As the lower surface of the corrugated cardboard, the lower surface layer 7 can protect the support layer 6 from external wear and environmental influences, ensuring the structural stability and support performance of the support layer 6.

The elastic pads 8 are evenly distributed on the upper surface of the base plate 3, and the number is determined according to the actual buffering needs. Usually, several are set. The elastic pads 8 are made of environmentally friendly elastic materials with high elasticity and high resilience, such as natural rubber and biodegradable elastic plastics. When subjected to external impact, the elastic pads 8 can absorb a large amount of impact energy through their own compression deformation, effectively reducing the impact of the impact force on the internal items. The tension plates 9 are fixed on the outer surface of the elastic pads 8 and are made of environmentally friendly film materials with high strength and good flexibility, such as biodegradable polyester film. The tension plates 9 can not only play a certain protective role for the elastic pads 8, preventing the elastic pads 8 from being worn or damaged during use, but also limit the excessive deformation of the elastic pads 8 through their own tension when the elastic pads 8 deform, ensuring that the elastic pads 8 can quickly return to their original shape and ensuring the stability and durability of the buffering performance.

[0024] Example 3:

[0025] This embodiment provides a high-cushioning environmentally friendly corrugated cardboard, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0026] Support layer 6 includes: Hexagonal support columns 10: Several hexagonal support columns 10 are fixedly and evenly arranged on the lower surface of the intermediate layer 1.

[0027] As can be seen in this embodiment, the support layer 6 is mainly composed of hexagonal support columns 10. The hexagonal support columns 10 are fixed to the lower surface of the intermediate layer 1. Several hexagonal support columns 10 are evenly arranged to form a stable support structure. The hexagonal structure has excellent mechanical properties and can evenly distribute pressure. The hexagonal support columns 10 are made of paper material. Compared with other shapes of support structures, with the same amount of material, the hexagonal support columns 10 can provide stronger support and stability, effectively improving the overall load-bearing capacity of the corrugated cardboard.
