Detailed Description

In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings.

The embodiment of the utility model discloses a corrugated board with high toughness.

The utility model provides a corrugated board with strong toughness as shown in figures 1-3, which comprises two symmetrically arranged surface layers 1, wherein a partition board 2 is arranged between the two surface layers 1, a wave core paper interlayer 3 is arranged between the two surface layers 1 and two sides of the partition board 2, a plurality of reinforcing rods 4 are respectively penetrated into the two wave core paper interlayers 3, the two wave core paper interlayers 3 are staggered, and the upper reinforcing rods 4 and the lower reinforcing rods 4 are staggered.

Through the setting of two-layer wave core paper intermediate layer 3 to insert many reinforcing rods 4 in wave core paper intermediate layer 3 inside, make corrugated container board shaping after, can offset horizontal or vertically received pressure, avoid corrugated container board to take place to buckle as far as possible, thereby improve corrugated container board's toughness on the whole.
