Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboards, in particular to an anti-delamination corrugated paperboard with an edge reinforcement structure. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least a layer of corrugated core paper interlayer (commonly known as "corrugated sheet", "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "box board", "box board"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] Corrugated cardboard is made of face paper, paper core and bottom paper as its basic structure, but corrugated cardboard has poor waterproofness and compressive strength. The edges of corrugated cardboard are prone to delamination and deformation, which affects its service life, so improvements are needed. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-delamination corrugated paperboard with an edge reinforcement structure to solve the problem of easy delamination and deformation of the edges of the corrugated paperboard proposed in the above background art.

[0006] The supporting assembly includes a supporting column, and a first protective layer and a second protective layer are respectively provided on both sides of the supporting column.

[0007] Preferably, the support column is made of rubber material, and an elastic hole is opened inside the support column.

[0008] Preferably, a plurality of elastic holes are provided, and the elastic holes are distributed at equal intervals longitudinally with respect to the interior of the support column.

[0010] Preferably, the support columns, the first protective layer and the second protective layer are provided in multiple groups, and the multiple groups of support columns, the first protective layer and the second protective layer are distributed with equal intervals in the horizontal direction with respect to the upper and lower ends of the inner paper.

[0011] Preferably, outer walls of the face paper and the base paper are both provided with a waterproof layer, and the material of the waterproof layer is a waterproof coating.

[0012] Preferably, the support columns, the first protective layer and the second protective layer are staggered with the paper core.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) This device can improve the pressure resistance and waterproofness of the edge, thereby avoiding the phenomenon of delamination and deformation caused by moisture and softening of the edge, and improving the service life of the device.

[0015] (2) The device distributes multiple groups of support components at equal intervals between the inner paper, the outer paper and the paper core. The first protective layer, the support column and the second protective layer of the support components can improve the waterproof performance and pressure resistance of the edge of the device, thereby avoiding the occurrence of edge delamination and increasing the service life of the device.

[0016] (3) This device uses a support column made of rubber material and opens an elastic hole inside the support column, which not only ensures the supporting performance of the support column, but also improves the deformation performance of the support column, thereby improving the compressive resistance of the edge of the device.
