Description

High-strength light-weight kraft board

Technical Field

The utility model relates to the technical field of kraft paper boards, in particular to a high-strength and light-weight kraft paper board.

Background

Paperboard is a sheet-like material made from pulp, commonly used for packaging, printing and making various paper products, and is formed by bonding multiple layers of paper, and has good strength, stability and plasticity;

At present, when goods are carried, if the cartons made of the kraft paper board are bumped or collide with sharp objects, the cartons can be punctured, so that the goods in the cartons are damaged, and in order to prevent the cartons from being punctured, a plurality of hard layers are usually added in the cartons, so that the cartons become thick and heavy, and inconvenience is brought to carrying the goods;

Accordingly, the present utility model provides a high strength and lightweight kraft board to overcome and ameliorate the shortcomings of the prior art.

Disclosure of utility model

In order to solve the technical problems, the technical scheme includes that the high-strength light-weight kraft board comprises board bodies which are symmetrically arranged, connecting rods are fixedly connected between adjacent board bodies at equal intervals, cavities are formed between the adjacent connecting rods, paper cores are filled in the cavities, and a fiber layer is adhered to one surface, far away from the connecting rods, of the board bodies.

Preferably, the paperboard plate body comprises a lower plate layer fixedly connected with the connecting rod, a buffer core is adhered to one surface, far away from the connecting rod, of the lower plate layer, and an upper plate layer is adhered to the outer surface of the buffer core.

Preferably, the paper core is made of foam.

Preferably, the buffer core is wavy, and the upper plate layer is made of materials with honeycomb holes at equal intervals.

Preferably, the fiber layer is made of carbon fiber, and the leather layer is adhered to the outer surface of the fiber layer.

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

The buffer core is wavy so as to buffer with the cavity layer by layer, the board body is light in weight, the transportation weight is reduced, the transportation is convenient, the board body is made of a fiber layer made of carbon fibers and a leather layer bonded on the outer surface, the tensile and tear resistance performance can be greatly improved, the board body is more suitable for high-requirement packaging, and the connecting rod is used for fixing the upper board layer and the buffer core through the lower board layer, so that the board is firmer.
