Description

TECHNICAL FIELD

[0001] The utility model relates to kraft paper board technical field, concretely relates to a high strength light kraft paper board. BACKGROUND

[0002] The paperboard is a kind of board-shaped material made of paper pulp, is usually used for packaging, printing and making various paper products, it is formed by multiple paper sheets through bonding, has good strength, stability and plasticity;

[0003] At present, when carrying goods, if the carton made of kraft paper board is subjected to knock or encounters the collision of sharp object, it can cause the carton to be punctured, thereby causing damage to the goods in it, and some kraft paper boards usually increase many hard layers in its interior to prevent puncture, which will cause kraft paper board to become thick and heavy, and bring inconvenience to carrying goods;

[0004] Therefore, the utility model provides a high strength light kraft paper board to make up for and improve the shortcomings of prior art. INVENTION CONTENTS

[0005] To solve the above technical problems, the technical scheme that the utility model adopts is as follows: a high strength light kraft paper board, including symmetrically arranged paperboard plate bodies, equidistantly fixedly connected with connecting rods between adjacent paperboard plate bodies, a cavity is arranged between adjacent connecting rods, the cavity is filled with a paper core, and the side of the paperboard plate body away from the connecting rod is bonded with a fiber layer.

[0006] Preferably, the paperboard plate body includes a lower plate layer fixedly connected to the connecting rod, the side of the lower plate layer away from the connecting rod is bonded with a buffer core, and the outer surface of the buffer core is bonded with an upper plate layer.

[0007] Preferably, the paper core is of foam material.

[0008] Preferably, the buffer core is in wave shape, and the upper plate layer is equidistantly provided with honeycomb holes in material.

[0009] Preferably, the fiber layer is of carbon fiber, and the outer surface of the fiber layer is bonded with a leather layer.

[0010] Compared with the prior art, the utility model has the beneficial effects that:

[0011] The buffer core set in the utility model is in wave shape, so as to buffer layer by layer with the cavity, and make the plate body light in weight, reduce transportation weight and facilitate transportation, the fiber layer of carbon fiber and the leather layer bonded on the outer surface can greatly improve the tensile and tear resistance, make it more suitable for high requirement packaging, and the connecting rod fixes the upper plate layer and the buffer core through the lower plate layer, so that the paperboard is more firm.
