Abstract

This utility model relates to a high-strength paperboard, comprising a base paperboard, a face paperboard, and a corrugated paperboard. A first dividing beam is provided on the upper surface of the base paperboard, and multiple rectangular lower corrugated paper layers are disposed inside the first dividing beam. A second dividing beam is provided on the upper side of the first dividing beam, and multiple triangular upper corrugated paper layers are disposed inside the second dividing beam. Both the lower and upper corrugated paper layers are formed by folding and splicing the corrugated paperboard. The face paperboard is disposed on the upper surface of the second dividing beam. By folding and splicing the corrugated paperboard into lower and upper corrugated paper layers, the lower and upper corrugated paper layers intersect at different angles and have different textures. This avoids bending of the paperboard along the texture and increases the elasticity and deformation capacity of the paperboard in multiple directions, thus improving the paperboard's compression resistance, cushioning, lightweight, and stability.
