Description

Technical Field

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

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper (commonly known as "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of cardboard (also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated boxes depends on three factors: the characteristics of the core paper and cardboard and the structure of the box itself. Corrugated cardboard, also known as corrugated cardboard, is mainly used to make cardboard boxes, cardboard sandwiches and other packaging materials for fragile goods. Cardboard boxes made of corrugated cardboard have good light-shielding properties and are relatively cheap, and are deeply loved by consumers from all walks of life.

[0003] The existing corrugated cardboards are mostly U-shaped, V-shaped and UV-shaped. Although the structure has high elasticity, the overall structural strength is low. It will easily deform when squeezed, thereby damaging the goods stored inside, and the protection effect is poor. In addition, since the main material of the corrugated cardboard is supported by paper, when it encounters water, the cardboard will become soft due to the immersion of water, thereby reducing the support effect. To this end, we propose a high-strength corrugated cardboard. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-strength corrugated paperboard, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A high-strength corrugated paperboard comprises an outer paperboard and an inner paperboard, and also comprises a reinforcement component for reinforcing the corrugated paperboard body, wherein the reinforcement components are provided in plurality, wherein a first support plate and a second support plate are respectively bonded and connected on both sides of the reinforcement component, an outer side wall of the first support plate is bonded and connected to a first UV-shaped corrugated paper core, an outer side wall of the second support plate is bonded and connected to a second UV-shaped corrugated paper core, and the outer paperboard and the inner paperboard are respectively bonded and connected to the outer side walls of the first UV-shaped corrugated paper core and the second UV-shaped corrugated paper core.

[0007] Furthermore, the outer paperboard comprises a base plate, and an anti-tear film is adhesively connected to an outer side wall of the base plate.

[0008] Furthermore, the outer side wall of the tear-resistant film is adhesively connected with a waterproof film.

[0009] Furthermore, the reinforcement component comprises a solid paper column, and a paper support column is fixedly sleeved on the outer side wall of the solid paper column.

[0010] Furthermore, the first support plate and the second support plate are both made of cardboard.

[0011] Furthermore, the inner wall of the inner paperboard is adhesively connected with a waterproof film.

[0012] Compared with the prior art, the utility model has the following beneficial effects: 1. The utility model uses the first UV-shaped corrugated paper core, the first support plate, the paper support column, the paper solid column, the second support plate and the second UV-shaped corrugated paper core. In daily use, the first UV-shaped corrugated paper core and the second UV-shaped corrugated paper core can effectively buffer the impact force, improve the impact resistance of the corrugated paperboard body when in use, and use the hard first support plate and the second support plate as well as the paper support column and the paper solid column arranged on the inner side to improve the structural strength of the corrugated paperboard body, so that the corrugated paperboard is used It will not be easily deformed, ensuring the supporting effect and improving the protective effect of the corrugated cardboard products when in use; 2. The utility model sets a waterproof film and an anti-tear film. When in use, the waterproof film can improve the hydrophobicity of the corrugated cardboard. When water falls on the surface of the outer cold cardboard, the waterproof film allows the water to flow to the periphery to avoid water from penetrating into the surface of the corrugated cardboard, thereby improving the waterproof effect of the corrugated cardboard. The anti-tear film can improve the tear resistance of the waterproof film, so it will not be easily torn during daily use, effectively improving the use effect of the waterproof film and ensuring the waterproof effect of the corrugated cardboard.
