Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated paperboard technical field, specifically to a kind of high-strength deformation-preventing corrugated paperboard. BACKGROUND

[0002] Corrugated paperboard is also called corrugated paperboard, which is made of at least one layer of corrugated paper and one layer of boxboard paper. It has good elasticity and extensibility, and is mainly used for manufacturing paper boxes, sandwich of paper boxes and other packaging materials for fragile goods. It is mainly made of homemade straw pulp and waste paper, which is beaten into a kind of yellow paperboard, and then rolled into corrugated shape by mechanical processing. Then, it is bonded with boxboard paper on its surface using sodium silicate or other adhesives.

[0003] The existing corrugated paperboard has poor tear resistance. Most of them are simply used for storing goods. When the corrugated paperboard comes into contact with the ground and collides, it is easy to break. The corrugated paperboard itself does not have a tear-resistant structure, which causes unnecessary economic losses due to the exposure of the products in the package, thereby reducing the use effect.

[0004] Therefore, in view of the above, the utility model provides a kind of high-strength deformation-preventing corrugated paperboard to make up for and improve the shortcomings of prior art. UTILITY MODEL CONTENT

[0006] Hardboard, hardboard is arranged between core board base layer and kraft paper layer;

[0007] Reinforced paperboard, reinforced paperboard is fixedly connected to the outer surface of hardboard;

[0008] Glue layer, glue layer is provided with multiple, and glue layer is equidistantly opened on hardboard:

[0009] Tear-resistant film, tear-resistant film is coated and pasted on the outer surface of kraft paper layer.

[0010] As preferred, a plurality of through slots are formed on the hardboard, and a pulling plate is fixedly connected to the outer surface of the reinforced paperboard.

[0011] As preferred, the reinforced paperboard is in the shape of a rice character, and multiple reinforced paperboards are provided.

[0012] As preferred, a buffer groove is formed on the reinforced paperboard, and a filler is filled between adjacent reinforced paperboards.

[0013] As preferred, a mesh reinforcement rib is fixed to one end surface of the hardboard close to the reinforced paperboard.

[0014] Preferably, the filler is in honeycomb shape, and the width of the buffer groove is between 0.1mm and 0.3mm.

[0015] Compared with the prior art, the utility model has the beneficial effects that:

[0016] The strengthening paperboard in the rice shape is used to block the external pulling force on the paperboard, and the adjacent strengthening paperboard is supported and buffered by the filler in the honeycomb shape, so that the pulling force is weakened and the original shape is restored.
