Description

Technical Field

[0001] This application relates to the field of paperboard, and in particular to a corrugated paperboard with good cushioning properties. Background Technology

[0002] Corrugated cardboard is an environmentally friendly material widely used in the packaging industry. Its unique structural design provides excellent cushioning performance and a certain level of compressive strength. It is typically made from multiple layers of paper through bonding and pressing processes, including at least one layer with a corrugated or similar structure. This structure gives corrugated cardboard superior compressive strength and cushioning capabilities. Corrugated cardboard is not only low-cost and easy to process, but also has good recyclability and environmental friendliness, making it widely used in the packaging of various products such as food, electronic products, and daily necessities.

[0003] Traditional corrugated cardboard typically consists of an outer corrugated cardboard layer and an inner cushioning paper layer. The outer corrugated cardboard provides the main compressive strength through its corrugated structure, while the inner cushioning paper layer is mostly corrugated kraft paper, used to absorb impact and protect the contents of the package from damage.

[0004] While traditional corrugated cardboard has a certain compressive strength, when subjected to a large impact, the inner cushioning paper is squeezed and deformed, losing its cushioning effect. As a result, corrugated cardboard cannot effectively protect the items inside the packaging from damage. Utility Model Content

[0005] The purpose of this application is to solve the problem mentioned in the background art that when subjected to a large impact, the inner cushioning paper is squeezed and deformed, and can no longer produce a cushioning effect, resulting in the corrugated cardboard being unable to effectively protect the contents of the package from damage. This application provides a corrugated cardboard with good cushioning properties.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A type of corrugated cardboard with good cushioning properties includes a first corrugated cardboard, a second corrugated cardboard disposed on the first corrugated cardboard, a first cushioning layer disposed between the first corrugated cardboard and the second corrugated cardboard, a second cushioning layer disposed on the first cushioning layer, a reinforcing layer disposed between the first cushioning layer and the second cushioning layer, and a waterproof layer fixed between the first corrugated cardboard and the first cushioning layer, and between the second corrugated cardboard and the second cushioning layer.

[0008] By adopting the above technical solution, a buffer layer 1 and a buffer layer 2 are added between corrugated cardboard 1 and corrugated cardboard 2, and a reinforcing layer is added between buffer layer 1 and buffer layer 2. This allows the corrugated cardboard to effectively absorb and disperse external impacts, and at the same time, it can recover its original shape after being squeezed, protecting the packaged items from damage.

[0009] Furthermore, the thickness of both corrugated cardboard one and corrugated cardboard two is 3mm.

[0010] By adopting the above technical solution, using 3mm thick corrugated cardboard one and corrugated cardboard two as the surface of the corrugated cardboard, the impact resistance and strength of the corrugated cardboard can be effectively increased.

[0011] Furthermore, the first buffer layer is a sponge paper layer, and the thickness of the first buffer layer is 3mm.

[0012] By adopting the above technical solution, a 3mm thick sponge paper layer is used as the first buffer layer to absorb the impact force, thereby improving the impact resistance of the corrugated cardboard.

[0013] Furthermore, the second buffer layer is an air cushion paper layer, and the second buffer layer is 3mm thick.

[0014] By adopting the above technical solution, a 3mm thick air cushion paper layer is used as the second buffer layer to further utilize the air cushion paper layer for buffering, thereby further improving the buffering performance and strength of the corrugated cardboard.

[0015] Furthermore, the reinforcing layer includes several reinforcing strips fixed on the buffer layer, and several reinforcing strips are fixed on the buffer layer. The reinforcing strips are perpendicular to each other. The buffer layer is fixedly connected to the reinforcing strips and the second reinforcing strip. The reinforcing strips are sponge strips.

[0016] By adopting the above technical solution, several reinforcing strips 1 and 2 are fixed between buffer layer 1 and buffer layer 2, thereby further enhancing the buffering capacity of the anti-cardboard.

[0017] Furthermore, both reinforcing strip one and reinforcing strip two have support strips fixed inside them.

[0018] By adopting the above technical solution, support strips are added to the first and second reinforcing strips, and the strength of the first and second reinforcing strips is increased by the support strips, thereby increasing the strength of the entire corrugated cardboard.

[0019] Furthermore, the support strip is a flexible rubber strip.

[0020] By adopting the above technical solution, the support strip is made of flexible rubber material, which can reduce the obstruction of the support strip on the cutting groove cardboard, and at the same time improve the tear resistance of the cardboard.

[0021] Furthermore, the waterproof layer is a waterproof membrane, which is a polymer film.

[0022] By adopting the above technical solution, the polymer waterproof membrane is laid and fixed on corrugated cardboard one and corrugated cardboard two respectively, thereby enhancing the waterproof strength of the entire corrugated cardboard.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application achieves the purpose of effectively absorbing and dispersing external impacts on the corrugated cardboard by using environmentally friendly adhesive to bond a sponge paper layer to a corrugated cardboard first, making the sponge paper layer serve as a cushioning layer one, and using environmentally friendly adhesive to bond an air cushion paper layer to a corrugated cardboard second, making the air cushion paper layer serve as a cushioning layer two. The cushioning layer one on the corrugated cardboard first and the cushioning layer two on the corrugated cardboard second are brought together by using environmentally friendly adhesive and then bonded together.

[0025] 2. In this application, before bonding the first and second buffer layers together, a support strip is inserted between the first and second reinforcing strips to support them. Several evenly distributed first and second reinforcing strips are then bonded to the first buffer layer using environmentally friendly adhesive, with the first and second reinforcing strips arranged perpendicularly to each other. Finally, the second buffer layer is bonded to the evenly distributed first and second reinforcing strips using environmentally friendly adhesive. This achieves the purpose of further improving the cushioning effect of the corrugated cardboard and its tear resistance, thereby further protecting the packaged goods from damage.

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a corrugated cardboard with good cushioning properties.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A type of corrugated cardboard with good cushioning properties includes corrugated cardboard 1, corrugated cardboard 2 on corrugated cardboard 1, cushioning layer 3 between corrugated cardboard 1 and corrugated cardboard 2, cushioning layer 4 on cushioning layer 3, reinforcing layer 5 between cushioning layer 3 and cushioning layer 4, and waterproof layer 6 fixed between corrugated cardboard 1 and cushioning layer 3, and between corrugated cardboard 2 and cushioning layer 4.

[0034] In addition, the thickness of both corrugated cardboard 1 and corrugated cardboard 2 is 3mm.

[0035] Furthermore, the buffer layer 3 is a sponge paper layer with a thickness of 3mm.

[0036] Furthermore, the second buffer layer 4 is an air cushion paper layer, and the second buffer layer 4 is 3mm thick.

[0037] First, a waterproof layer 6 is fixed to the inner layer of corrugated cardboard 1. A sponge paper layer is then bonded to the waterproof layer 6 of corrugated cardboard 1 using environmentally friendly adhesive, serving as a cushioning layer 3. Next, a waterproof layer 6 is fixed to corrugated cardboard 2. An air cushion paper layer is then bonded to the waterproof layer 6 of corrugated cardboard 2 using environmentally friendly adhesive, serving as a cushioning layer 4. The cushioning layers 3 and 4 on corrugated cardboard 1 and 2 are then pressed together using environmentally friendly adhesive and bonded together. Finally, a pressing device is used to ensure a tight bond between the layers. By adding a sponge paper layer and an air cushion paper layer as cushioning layers 3 and 4 between corrugated cardboard 1 and 2, a multi-layered structure is formed in the corrugated cardboard. This allows the corrugated cardboard to effectively absorb and disperse external impacts, and to recover its original shape after being compressed, protecting the packaged goods from damage.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The reinforcing layer 5 includes several reinforcing strips 51 fixed on the buffer layer 3. Several reinforcing strips 51 are fixed on the buffer layer 3. The reinforcing strips 51 and 52 are distributed vertically. The buffer layer 4 is fixedly connected to the reinforcing strips 51 and 52. The reinforcing strips 51 and 52 are sponge strips.

[0039] In addition, both reinforcing strip 1 51 and reinforcing strip 2 52 have support strips 53 fixed inside.

[0040] Furthermore, the support strip 53 is a flexible rubber strip.

[0041] Before bonding the first buffer layer 3 and the second buffer layer 4 together, a support strip 53 is first inserted between the first reinforcing strip 51 and the second reinforcing strip 52 to support them. Several evenly distributed first reinforcing strips 51 and the second reinforcing strip 52 are then bonded to the first buffer layer 3 using environmentally friendly adhesive. The first reinforcing strips 51 and the second reinforcing strip 52 are arranged perpendicularly to each other. The second buffer layer 4 is then bonded to the several evenly distributed first reinforcing strips 51 and the second reinforcing strip 52 using environmentally friendly adhesive, thus fixing the first reinforcing strips 51 and the second reinforcing strip 52. By adding several vertically distributed first reinforcing strips 51 and the second reinforcing strip 52 between the first buffer layer 3 and the second buffer layer 4, and by adding support strips 53 to the first reinforcing strips 51 and the second reinforcing strip 52, the cushioning effect of the corrugated cardboard can be further improved, as can its tear resistance, thus further protecting the packaged items from damage.

[0042] Reference Figure 1 and Figure 2 Waterproof layer 6 is a waterproof membrane, which is a thin film of polymer material. The polymer material waterproof membrane is laid and fixed on corrugated cardboard 1 and corrugated cardboard 2 respectively. The waterproof membrane increases the waterproof effect of corrugated cardboard 1 and corrugated cardboard 2. By fixing the waterproof membrane on corrugated cardboard 1 and corrugated cardboard 2, the waterproof strength of the entire corrugated cardboard can be enhanced.

[0043] Working principle: First, a waterproof layer 6 is fixed to the inner layer of corrugated cardboard 1. A sponge paper layer is then bonded to the waterproof layer 6 of corrugated cardboard 1 using environmentally friendly adhesive, serving as a cushioning layer 3. Next, a waterproof layer 6 is fixed to corrugated cardboard 2. An air cushion paper layer is then bonded to the waterproof layer 6 on corrugated cardboard 2 using environmentally friendly adhesive, serving as a cushioning layer 4. Supporting strips 53 are inserted between reinforcing strips 51 and 52 to support them. Several evenly distributed reinforcing strips 51 and 52 are then bonded to the cushioning layer 3 using environmentally friendly adhesive, with the reinforcing strips 51 and 52 arranged perpendicularly. The cushioning layer 4 is then bonded to the evenly distributed reinforcing strips 51 and 52 using environmentally friendly adhesive. Finally, a pressing device is used to press the layers together, ensuring a tight bond between them.
