Embodiment Construction

[0030] The present invention will be more clearly and completely described below by means of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0031] Such as figure 1 and figure 2 As shown, the corrugated cardboard according to the embodiment of the present invention includes a corrugated cardboard layer 1, a yarn layer 2 and a first face paper layer 3 which are stacked sequentially from bottom to top, and the two sides of the yarn layer 2 are respectively bonded to the corrugated cardboard layer 1 and the One side paper layer 3. Through the yarn layer 2, the puncture strength, burst resistance and tensile strength of the corrugated cardboard are greatly improved, effectively avoiding the damage caused by the abrasion of the corrugated cardboard. At the same time, the corrugated paper layer 1, the yarn layer 2 and the first face paper layer 3 are all completely recyclable and reusable r...

Abstract

The invention discloses a corrugated cardboard, which comprises a corrugated paper layer, a yarn layer and a first surface paper layer, wherein the corrugated paper layer, the yarn layer and the firstsurface paper layer are sequentially stacked from bottom to top, and both sides of the yarn layer are bonded to the corrugated paper layer and the first surface paper layer respectively. According tothe invention, the tearing strength, the bursting strength and the tensile strength of the corrugated cardboard are greatly improved through the yarn layer, the damage caused by the abrasion of the corrugated cardboard is effectively avoided, and the product material of the yarn layer is a completely recyclable raw material, so that the cost is low, and the popularization and application are easy.

Description

technical field [0001] The invention relates to a corrugated cardboard. Background technique [0002] As the most important and widely used packaging material, corrugated cardboard can play a role in buffering external shocks during transportation, so it can protect the products in the packaging during transportation. At the same time, it is light in weight, low in cost, easy to process, and convenient storage and other advantages. During the transportation process, the products in the package often collide with the corrugated cardboard. Due to the poor puncture strength, burst resistance and tensile strength of the surface paper used in the existing corrugated cardboard structure, the corrugated cardboard is easily damaged due to abrasion. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a corrugated cardboard for overcoming the defect that the existing corrugated cardboard is damaged due to wear. [0004] The ...
