Description

High-strength composite corrugated board

Technical Field

The application belongs to the technical field of corrugated paper processing, concretely relates to compound corrugated container board of high strength.

Background

Corrugated paper is a plate-like object formed by bonding corrugated paper formed by processing a corrugated roll with a liner paper. The corrugated paper has good mechanical strength, can bear certain pressure from the plane, is rich in elasticity, has good buffering effect, can resist collision and falling in the carrying process, and is mainly used for manufacturing paper boxes, paper box sandwiches and other packaging materials of fragile commodities. The corrugated paper is more and more widely applied, and is used for replacing other wood products and steel products in some fields, and the traditional corrugated paper is basically formed by adding a paper core and a paper panel, so that the strength is not enough, the deformation and the damage are easy, and the service life is short. The high-strength corrugated paper board with double corrugated paper cores can meet the requirements.

At present, the corrugated board with the high-strength double-corrugated paper core is mostly replaced by increasing the thickness or using a material with higher structural strength for improving the structural strength, so that the weight and the volume of the corrugated board are increased, the using effect is poor, and the using requirement can not be met.

Accordingly, one skilled in the art has provided a high strength composite corrugated cardboard to solve the problems set forth in the above background art.

SUMMERY OF THE UTILITY MODEL

The utility model provides a compound corrugated container board of high strength is provided in the not enough of prior art of overcoming to the aim at of this application.

In order to achieve the purpose, the technical scheme provided by the application is as follows: the utility model provides a compound corrugated container board of high strength, includes first surface paper layer, the upper end position of first surface paper layer is equipped with the second surface paper layer that is parallel to each other, first surface paper layer with link together through the filling layer between the second surface paper layer, the filling layer comprises a plurality of refill, the refill is the rectangular of "theta" shape for the cross-section.

According to a further technical scheme, the paper core is arranged into a single layer or multiple layers.

According to a further technical scheme, the paper cores are distributed in a staggered mode or are distributed at equal intervals along one edge of the first face paper layer.

After the above scheme is adopted, the beneficial effects of the application are as follows:

this application sets up the refill that the cross-section is "theta" shape and as the filling layer, can receive when corrugated container board collides, and the impact that will receive carries out the cushioning regulation, reduces corrugated container board's deformation volume, inside stress size when reducing to indirectly increase corrugated container board's structural strength, improve corrugated container board life's problem.
