As a further aspect, the outer paper, the inner paper and the flat core paper have the same thickness.
As a further aspect, the thickness of the straight core paper is smaller or larger than the thickness of the outer paper or the inner paper. Since the high strength six ply corrugated board is primarily used in heavy duty loading applications, the thickness of the outer or inner face paper can be increased appropriately compared to the thickness of the straight core paper to reduce the risk of scratching the surface.
As a further proposal, the flute height of the corrugated medium is 2.8-5.5mm. The corrugated shapes used in the paper boxes are generally 5 types of A, C, B, E and F, the arrangement sequence from high to low is A, C, B, E, F, and each type of flute height has industry standards.
The flute direction of the corrugated medium points to the width direction of the six layers of corrugated boards.
The beneficial effects of the utility model are as follows:
(1) The stupefied tip and stupefied tip of two layers of corrugated medium paper in the high-strength six-layer corrugated board are relatively attached, and under the condition that the bearing capacity of the stupefied tip is not weakened, the straight medium paper connected with the adjacent two layers of corrugated medium paper is omitted, the material cost is saved, the corresponding processing energy consumption is reduced, and the high-strength six-layer corrugated board is lower in carbon and environment-friendly.
(2) Compared with the traditional seven-layer corrugated board, the six-layer corrugated board of the high-strength six-layer corrugated board has three layers of corrugated medium paper, the two layers of corrugated medium paper are directly and pointedly attached to each other, the middle transitional straight medium paper is omitted, and the supporting force is stronger, so that the application of the traditional seven-layer corrugated board is completely replaced.
