Problems solved by technology

However, such methods are limited to improving the strength and impact resistance of corrugated cardboard, which not only wastes resources, but also reduces packaging space
However, traditional corrugated cardboard has defects in the mechanical strength, moisture-proof and waterproof, and anti-static issues that need to be solved for the packaging and storage of large items.

Embodiment Construction

[0007] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0008] like figure 1 The layered corrugated cardboard shown includes kraft paper and corrugated paper, and is characterized in that: a layer of corrugated paper core is sandwiched between the two kraft papers, and the lower surface of the outer kraft paper of the corrugated paper core is bonded to the upper surface of the bottom kraft paper, An antistatic plastic film is attached to the surface of the outer kraft paper.

[0009] Inspired by the above-mentioned ideal embodiment according to the present invention, through the above-mentioned description content, relevant workers can make various changes and modifications within the scope of not departing from t...

Abstract

The invention discloses a layered corrugated paper board, which comprises kraft paper and corrugated paper. The layered corrugated paper board is characterized in that a layer of corrugated paper core is arranged between two kraft paper layers, the surfaces of the corrugated paper core layer are respectively adhered to the lower surface of the upper kraft paper layer and the upper surface of the lower kraft paper layer, and an antistatic plastic film is covered on the surface of the upper kraft paper.

Description

technical field [0001] The invention relates to a cardboard, especially a layered corrugated cardboard. Background technique [0002] Corrugated cardboard has the advantages of good shock resistance, printability, light weight, and recyclability, and is widely used in product packaging and other fields. At present, the commonly used corrugated cardboard has a three-layer corrugated cardboard structure composed of outer paper on the upper and lower surfaces and corrugated paper in the middle. It has low strength and poor impact resistance, which limits the packaging and transportation of some special products. In order to improve the strength and impact resistance, the number of corrugated layers is usually increased to form a five-layer, seven-layer or nine-layer cardboard structure. Because the thickness of corrugated cardboard is directly proportional to the strength of corrugated cardboard. However, such methods are limited to improving the strength and impact resistanc...
