Problems solved by technology

For corrugated cardboard used for storage and transportation of special items, the number of layers of corrugated paper is usually increased to five layers, seven layers and other cardboard structures. Obviously, as the thickness of corrugated cardboard increases, the strength of corrugated cardboard also increases, but this depends on Increasing the number of layers of corrugated paper to increase the seismic performance not only wastes resources, but also reduces the space used for packaging products

Embodiment approach

[0048] Such as figure 1 As shown, take the first hollow corrugated paper core 1033 as an example of a hollow circular corrugated paper core, and take the second hollow corrugated paper core 1034 as an example of a hollow oval corrugated paper core. The corrugated paper core can be made of single-layer corrugated paper glued together. The circular corrugated paper core or the elliptical corrugated paper core has elasticity and can resist external impact to form a highly elastic corrugated paper board. In addition, in another embodiment, such as Figure 2-a shown and Figure 2-b as shown, Figure 2-b for Figure 2-a Take the second hollow corrugated paper core 1034 as a hollow inverted triangular corrugated paper core as an example, wherein the inverted triangular corrugated paper core can be made by bonding a single layer of corrugated paper, and the single layer of corrugated paper is folded into a triangle and bonded to obtain a hollow inverted triangle The corrugated pap...

Abstract

The present invention discloses a corrugated board, a composite corrugated cardboard and a composite corrugated box. High shock strength can be achieved by use of less corrugated paper. The present invention provides a corrugated board. The corrugated board comprises: a first surface paper layer, a second surface paper layer, and a corrugated paper layer arranged between the first surface paper layer and the second surface paper layer. The corrugated paper layer comprises a first waveform pattern part, a second waveform pattern part, a first hollow corrugated paper core, and a second hollow corrugated paper core, wherein a trough portion of the first waveform pattern part is bonded with a crest portion of the second waveform pattern par; a crest portion of the first waveform pattern part is bonded to the first surface paper layer; a trough portion of the second waveform pattern part is bonded to the second surface paper layer; the first hollow corrugated paper core is located above the trough portion of the first waveform pattern part and adhered to the first surface paper layer; and the second hollow corrugated paper core is located below the crest portion of the second waveform pattern part and adhered to the second surface paper layer.

Description

technical field [0001] The invention relates to the technical field of manufacturing packaging cartons, in particular to a corrugated cardboard, a composite corrugated cardboard and a composite corrugated cardboard box. Background technique [0002] Corrugated paper is currently widely used in the outer packaging of paper products. It has many advantages such as simple processing, light weight, high hardness, and easy storage. It is more and more popular among packaging companies and is widely used in the market. Product packaging, storage and transportation. [0003] Corrugated cardboard made of corrugated paper, in order to increase the shock resistance and stamping resistance, corrugated paper is generally provided with multiple layers, separated by core paper in the middle, and glued between layers of corrugated paper. For corrugated cardboard used for storage and transportation of special items, the number of layers of corrugated paper is usually increased to five laye...
