Embodiment 1

[0018] refer to figure 1 , the present embodiment includes an outer layer paper 1, a V-shaped corrugated paper core 2, an intermediate layer 3, a semicircular corrugated paper core 4 and a bottom layer of paper 5, forming a five-layer corrugated cardboard structure; the outer layer paper 1 and the intermediate layer 3 is a V-shaped corrugated paper core 2, and between the intermediate layer 3 and the bottom surface paper 5 is a semicircular corrugated paper core 4.

[0019] The outer surface paper 1 and the bottom surface paper 5 are 200g kraft paper; the intermediate layer adopts 200g corrugated medium paper; the V-shaped corrugated paper core 2 and the semicircular corrugated paper core 4 have the same height; the V-shaped corrugated paper core 2 and the semicircular corrugated paper core 4, the spans between the troughs are equal, and the spans between the peaks are equal; the direction of the grooves of the V-shaped corrugated paper core 2 and the direction of the grooves ...

Embodiment 2

[0022] refer to figure 2 , this embodiment includes outer layer paper 1', V-shaped corrugated paper core 2', semi-circular corrugated paper core 4' and bottom surface paper 5', forming a 4-layer corrugated board structure; V-shaped corrugated paper core 2' and semi-circular corrugated paper The crests and wave bottoms formed between the cores 5' are bonded to each other on the same vertical plane; the outer surface paper 1' and the bottom surface paper 5' are 200g kraft paper.

[0023] In this embodiment, there is no intermediate layer between the V-shaped corrugated paper core 2' and the semicircular corrugated paper core 5', so that the formed wave crests and wave bottoms are bonded to each other on the same vertical plane. Because the two sides of the semicircular corrugated paper core 4' give an axial force to the two sides of the V-shaped corrugated paper core 2', the structure can weaken the force in the vertical direction when it is impacted by an external force, so it...

Abstract

The invention provides a high-strength impact-resistant corrugated cardboard which comprises surface paper at an outer layer, a V-shaped corrugated paper core and surface paper at a bottom layer, and is also provided with a middle interlayer and a semi-circular corrugated paper core, wherein the V-shaped corrugated paper core is arranged between the surface paper at the outer layer and the middle interlayer, and the semi-circular corrugated paper core is arranged between the middle interlayer and the surface paper at the bottom layer. The high-strength impact-resistant corrugated cardboard synthesizes the high strength property of the V-shaped corrugated paper core and the impact-resistance of the semi-circular corrugated paper core, and improves the strength and impact-resistance of the corrugated cardboard simultaneously, thus being not only applicable to the packing of light products, but also especially applicable to the packing of large workpiece and heavy products.

Description

technical field [0001] The invention relates to a corrugated cardboard, in particular to a high-strength buffer-resistant corrugated cardboard. Background technique [0002] Corrugated cardboard has the advantages of good shock resistance, printability, light weight, and recyclability. It is often used in product packaging and other fields, and has a good market development prospect. [0003] At present, the commonly used corrugated cardboard generally has a three-layer corrugated cardboard structure composed of outer paper on the upper and lower surfaces and corrugated paper in the middle, which 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...
