Technical Field

[0001] The utility model relates to the technical field of corrugated white paperboards, in particular to a corrugated white paperboard with a moisture-proof bottom. Background Art

[0002] Corrugated cardboard is an important material used for packaging. With its unique structural design and excellent physical properties, it plays a vital role in logistics, transportation and packaging. Among them, the most widely used is corrugated white cardboard. Corrugated white cardboard is a commonly used packaging material. It is a composite cardboard made of corrugated paper and white cardboard bonded by adhesive. It mainly cushions the impact by the corrugated waves formed on the corrugated paper.

[0003] After the products are packaged with corrugated white cardboard, they are often stacked inside the warehouse for storage. When the corrugated paper is stacked inside the warehouse for a long time, the moisture on the warehouse floor will often corrode the bottom of the corrugated cardboard, thereby affecting the strength of the corrugated cardboard. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a corrugated white cardboard with a moisture-proof bottom, aiming to improve the problem in the prior art that when the corrugated paper is piled inside the warehouse for a long time, the moisture on the warehouse floor often causes corrosion to the bottom of the corrugated cardboard, thereby affecting the strength of the corrugated cardboard.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solution: a corrugated white paperboard with a moisture-proof bottom, comprising:

[0006] Corrugated paper, wherein a supporting paperboard is bonded and connected below the corrugated paper, and the supporting paperboard is used to enhance the compressive resistance of the corrugated paper;

[0007] The reinforcing layer is bonded to the bottom edge of the corrugated paper at its upper edge and fixedly bonded to the bottom surface of the supporting paperboard at its upper middle position;

[0008] Waterproof paper is bonded to the bottom surface of the reinforcement layer, and a waterproof membrane is fixedly bonded to the waterproof paper, which is used to block moisture.

[0009] As a further description of the above technical solution:

[0010] The supporting paperboard is configured as a wave-shaped structure

[0011] The support paperboard is internally bonded with a support tube, which is used to strengthen the strength of the support paperboard.

[0012] As a further description of the above technical solution:

[0013] Both ends of the support tube are designed to be open.

[0014] As a further description of the above technical solution:

[0015] A downwardly protruding cardboard is fixedly bonded to the edge of the bottom surface of the corrugated paper, and the bottom of the cardboard is bonded to the edge of the reinforcement layer.

[0016] The utility model has the following beneficial effects:

[0017] In the utility model, the crests and troughs of the wave structure of the supporting cardboard are designed to be staggered, so that air can pass smoothly when blown under the corrugated paper, thereby keeping the bottom of the corrugated paper dry. When the corrugated paper is placed on a relatively wet ground, a waterproof film can be used to block the moisture on the ground, so that the corrugated paper can be kept dry.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-3The present invention provides an embodiment of a corrugated white cardboard with a moisture-proof bottom, comprising a corrugated paper 1, a support cardboard 2 bonded to the bottom of the corrugated paper 1, a reinforcing layer 5 bonded to the bottom of the support cardboard 2. The reinforcing layer 5 is a rigid cardboard. Due to its high hardness, the reinforcing layer 5 is bonded to the bottom of the support cardboard 2 to prevent the corrugated paper 1 from bending. The upper edge of the reinforcing layer 5 is bonded to the bottom edge of the corrugated paper 1. In this embodiment, a downwardly protruding cardboard is fixedly bonded to the bottom edge of the corrugated paper 1, and the bottom of the cardboard is bonded to the edge of the reinforcing layer 5, thereby arranging the corrugated paper 1 and the reinforcing layer 5 together. The support cardboard 2 is located in the space formed by the reinforcing layer 5, the corrugated paper 1, and the cardboard.

[0025] In this embodiment, the supporting cardboard 2 is configured as a wavy structure, and the crests and troughs of the wavy structure of the supporting cardboard 2 are respectively bonded to the bottom surface of the corrugated paper 1 and the upper side surface of the reinforcing layer 5. The supporting cardboard 2 supports the corrugated paper 1, thereby increasing the compressive resistance of the corrugated paper 1.

[0026] The wave space of the support cardboard 2 is bonded with a support tube 6, and the bottom surface of the support tube 6 is bonded to the upper side surface of the reinforcement layer 5. The support tube 6 can support the support cardboard 2, thereby increasing the pressure resistance of the support cardboard 2, and then improving the support effect of the support cardboard 2 on the corrugated paper 1. The two ends of the support tube 6 are designed to be open, so that air can flow through the cavity inside the support tube 6, so that the bottom of the corrugated paper 1 and the support cardboard 2 can remain dry.

[0027] The bottom surface of the reinforcing layer 5 is bonded with waterproof paper 4, and the reinforcing layer 5 and the waterproof paper 4 are bonded and fixed in sequence by polyacrylate adhesive. The waterproof paper 4 under the reinforcing layer 5 is made of kraft paper, so as to prevent the waterproof membrane 3 from breaking due to accidental scratches. The waterproof paper 4 can temporarily replace the waterproof membrane 3 to block the moisture on the ground. The bottom surface of the waterproof paper 4 is bonded with the waterproof membrane 3, and the material of the waterproof membrane 3 is made of PVC (polyvinyl chloride), which can block the penetration of water molecules. When the corrugated paper 1 is placed on a relatively humid ground, the moisture on the ground can be blocked by the waterproof membrane 3 to prevent the moisture on the ground from entering the bottom of the corrugated paper 1 and affecting the strength of the corrugated paper 1. A hydrophobic coating is applied under the waterproof membrane 3 to prevent water droplets from staying on the surface of the waterproof membrane 3. The hydrophobic coating is a hydrophobic layer formed by spraying fluorocarbon compounds, silicones and other coatings.

[0028] It should be noted that the bonding connection of the above structures is achieved through water-resistant adhesive glue, such as polyacrylate adhesive, which can prevent the bonded structure on the corrugated paper 1 from falling off from the corrugated paper 1 due to moisture erosion when the corrugated paper 1 is used in a relatively humid environment.

[0029] Working principle: After applying adhesive on the bottom end of the corrugated paper 1, press the supporting cardboard 2 to the bottom end of the corrugated paper 1. At the same time, apply adhesive glue on the top of the reinforcement layer 5 and press it to the bottom of the supporting cardboard 2. In the same way, fix the waterproof paper 4 to the bottom end of the reinforcement layer 5. At the same time, fix the waterproof film 3 under the waterproof paper 4. The cooperation between the reinforcement layer 5 and the supporting cardboard 2 can increase the compressive strength of the corrugated paper 1. When the corrugated paper 1 is placed on the ground with high humidity, the waterproof film 3 under the waterproof paper 4 can block the moisture on the ground, thereby preventing the bottom end of the corrugated paper 1 from being in contact with the ground for a long time and moisture from entering the inside of the corrugated paper 1.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
