Problems solved by technology

The corrugated paper of corrugated cardboard in the prior art is mostly arranged horizontally in the corrugated layer in a wave shape. The cardboard with this structure has poor strength and weak impact resistance.
For the storage and transportation of special items, corrugated boxes with good shock resistance and good impact resistance are required for packaging. At present, in order to improve the strength and impact resistance, this effect is usually achieved by increasing the number of corrugated layers. In this way, The strength of corrugated cardboard is proportional to the thickness of corrugated cardboard, which leads to an increase in the space occupied by the package, increases the cost of logistics, and wastes resources

Embodiment Construction

[0011] refer to figure 1 As shown, a kind of corrugated cardboard comprises an outer layer of cardboard paper 1 and an inner layer of cardboard paper 6, the bottom of the outer layer of cardboard paper 1 is provided with a waterproof adhesive layer 2, and the bottom of the described waterproof adhesive layer 2 is provided with The first glue layer 3, the corrugated paper core 4 is arranged under the first glue layer 3, the second glue layer 5 is arranged under the corrugated paper core 4, and the inner box is arranged under the second glue layer 5 Cardboard6.

[0012] The corrugated paper core 4 is composed of a hexagonal paper core 41 and a buffer layer 7 arranged at intervals. The hexagonal paper core 41 is provided with a central circular paper core 42 and a number of paper cores tangent to the outer circumference of the central circular paper core. Small round paper cores 43, preferably eight small round paper cores 43. The hexagonal paper core 41, the central circular p...

Abstract

The invention discloses a damping corrugated board which comprises outer-layer case board paper and inner-layer case board paper. The damping corrugated board is characterized in that a waterproof glue layer is arranged below the outer-layer case board paper; a first glue layer is arranged below the waterproof glue layer; a corrugated paper core is arranged below the first glue layer; a second glue layer is arranged below the corrugated paper core; the inner-layer case board paper is arranged below the second glue layer; the corrugated paper core is formed by arranging and combining hexagonal paper cores and buffer layers at intervals; and each hexagonal paper core is internally provided with a center circular paper core body and multiple small circular paper core bodies tangent with the outer circumference of the center circular paper core. The damping corrugated board has the beneficial effects that the corrugated paper core is formed by arranging and combining the hexagonal paper cores and the buffer layers at intervals, so that the damping effect of the corrugated board is achieved; the number of layers of corrugated paper does not need to be increased; and the packaging space is better saved.

Description

technical field [0001] The invention relates to the field of corrugated cardboard, in particular to a shock-absorbing corrugated cardboard. Background technique [0002] Corrugated cardboard is mostly used for packaging and has a wide range of applications, so the demand is also very large. At present, the corrugated cardboard used in the production of packaging boxes is mainly composed of corrugated paper, face paper and inner paper. Most of the corrugated cardboard in the prior art is arranged horizontally in the corrugated layer in a wave shape, and the cardboard with this structure has poor strength and weak impact resistance. For the storage and transportation of special items, corrugated boxes with good shock resistance and good impact resistance are required for packaging. At present, in order to improve the strength and impact resistance, this effect is usually achieved by increasing the number of corrugated layers. In this way, The strength of corrugated cardboard...
