According to the utility model, the H-shaped reinforcing plate and the buffering particles are arranged, so that the strength of the corrugated board is enhanced, and the impact resistance of the corrugated board is enhanced.

Description

Double-buffering corrugated board

Technical Field

The utility model relates to the technical field of corrugated boards, in particular to a double-buffering corrugated board.

Background

The corrugated board is a multi-layer adhesive body, and the existing corrugated board at least consists of a core paper interlayer and paper boards positioned on two sides of the core paper interlayer. However, when the corrugated board with the above structure is subjected to extrusion force, the sandwich paper layer is easy to deform, so that the corrugated board is deformed integrally, and the corrugated board does not have a strong buffer structure and strength.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide a double-buffering corrugated board which is provided with an H-shaped reinforcing plate and buffering particles, so that the strength of the corrugated board is enhanced, and the shock resistance of the corrugated board is enhanced.

In order to solve the above technical problems, the present invention discloses a double-buffering corrugated cardboard, comprising: an upper layer of paperboard; the wavy paperboard layer is arranged below the upper paperboard layer; the double buffer layer is arranged below the wave paperboard layer and comprises H-shaped reinforcing plates which are closely arranged and buffer particles filled in upper and lower gaps of the H-shaped reinforcing plates; the lower paperboard is arranged below the double buffer layer; and the waterproof layers are arranged on the outer sides of the upper layer paper board and the lower layer paper board.

According to an embodiment of the utility model, the upper paperboard layer, the wave paperboard layer, the double buffer layer, the lower paperboard layer and the waterproof layer are sequentially adhered by glue.

According to an embodiment of the present invention, the thickness of the upper and lower layers of cardboard is 2 mm.

According to an embodiment of the present invention, the thickness of the double buffer layer is 3-5mm

According to an embodiment of the present invention, the thickness of the waterproof layer is 1 mm.

Compared with the prior art, the application can obtain the following technical effects:

1) through setting up H type reinforcing plate and buffering granule, both strengthened corrugated container board's intensity, strengthened corrugated container board's shock resistance again.

Of course, it is not necessary for any one product to achieve all of the above technical results simultaneously in the practice of the present invention.

Drawings

The accompanying drawings, which are included to provide a further understanding of the application and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the application and together with the description serve to explain the application and not to limit the application. In the drawings:

fig. 1 is a sectional view of a double buffered corrugated cardboard according to an embodiment of the present application.

Reference numerals

The corrugated cardboard comprises an upper layer of cardboard 10, a corrugated cardboard layer 20, a double buffer layer 30, an H-shaped reinforcing plate 31, buffer particles 32, a lower layer of cardboard 40 and a waterproof layer 50.

Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Referring to fig. 1, fig. 1 is a cross-sectional view of a double-cushioned corrugated cardboard according to an embodiment of the present application.

As shown, a double buffered corrugated cardboard comprises: an upper paperboard 10; a wave paperboard layer 20 disposed under the upper paperboard layer 10; the double buffer layer 30 is arranged below the wave paperboard layer 20, and the double buffer layer 30 comprises H-shaped reinforcing plates 31 which are closely arranged and buffer particles 32 which are filled in the upper and lower gaps of the H-shaped reinforcing plates 31; a lower paperboard 40 disposed under the double cushion layer 30; and a waterproof layer 50 disposed on the outer sides of the upper and

lower paper sheets

10 and 40.

In the embodiment of the present invention, the corrugated cardboard layer 20 is provided on the lower side of the upper layer cardboard 10, thereby enhancing the strength of the corrugated cardboard as a whole. Set up double buffer layer 30 under wave paperboard layer 20, double buffer layer 30 is including the H type reinforcing plate 31 of closely arranging and fill the buffering granule 32 of locating in the upper and lower space of H type reinforcing plate 31, through setting up H type reinforcing plate 31 and buffering granule 32, has both strengthened corrugated container board's intensity, has strengthened corrugated container board's shock resistance again. The lower paperboard layer 40 is arranged under the double buffer layer 30, and the waterproof layer 50 is arranged on the outer sides of the upper paperboard 10 and the lower paperboard 40, so that the overall waterproofness of the corrugated board is greatly enhanced.

It is worth mentioning that the upper layer paper board 10, the wave paper board layer 20, the double buffer layer 30, the lower layer paper board 40 and the waterproof layer 50 are sequentially pasted through glue, the thicknesses of the upper layer paper board 10 and the lower layer paper board 40 are both 2mm, the thickness of the double buffer layer 30 is 3-5mm, and the thickness of the waterproof layer 50 is 1 mm. The bonding mode is simple to operate and saves cost.

The foregoing description shows and describes several preferred embodiments of the present application, but as before, it is to be understood that the application is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the application as contemplated by the above teachings or as would normally occur to one skilled in the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the application, which is to be protected by the claims appended hereto.
