Corrugated cardboard is mainly used to make cartons, the sandwich of cartons, and other packaging materials for fragile goods. Corrugated cardboard is mainly made of traditional straw pulp and waste paper through pulping to make a raw cardboard similar to yellow cardboard, which is then machined and rolled into a corrugated shape, and then bonded to the boxboard with adhesives such as sodium silicate on its surface.

[0003] The corrugated waves of corrugated cardboard are like connected arched doors, arranged in a row and supporting each other to form a triangular structure. It has good mechanical strength, can withstand a certain amount of pressure from a plane, is elastic, and has a good cushioning effect.

[0004] The patent with announcement number CN219260588U discloses "a pressure-resistant corrugated cardboard structure, comprising: a multi-flute layer, the multi-flute layer is connected to a skeleton layer, the skeleton layer is connected to a single-flute layer, and the triple buffering of the multi-flute layer, the skeleton layer and the single-flute layer is used to alleviate external forces. The utility model has the following beneficial effects: This pressure-resistant corrugated cardboard structure is used to avoid the problems of poor strength and weak pressure-resistant buffering of previous corrugated box boards."

[0005] With respect to the above-mentioned related technologies, the inventors believe that in actual use, if water droplets splash on the corrugated cardboard, the surface of the corrugated cardboard will collapse and soften, thereby causing the corrugated cardboard to deform and affect the packaging. Utility Model Content

[0006] The utility model aims at the deficiencies of the prior art and provides a composite corrugated paperboard structure. The specific technical scheme is as follows:

[0007] A composite corrugated cardboard structure comprises a corrugated cardboard and a plastic film body compositely wrapped on the outer wall of the corrugated cardboard and used for waterproofing the corrugated cardboard, wherein the side wall of the plastic film body is provided with folding lines for providing a deformation space for the plastic film body after the corrugated cardboard structure is squeezed, and a plurality of anti-skid protrusions for preventing packaged items from slipping and separating the plastic film body and the packaged items are fixedly provided on both sides of the outer wall of the plastic film body.

[0008] By adopting the above technical solution, the waterproof performance of the corrugated board can be improved by wrapping the plastic film body, so that the corrugated board is not easily deformed by contact with water. When the corrugated board structure is squeezed, the plastic film body can be folded or stretched through the folding lines to provide a space for the plastic film body to deform, so that the plastic film body is not easily damaged when squeezed. The anti-slip protrusion can contact the packaged items to prevent the items from slipping, and can also separate the packaged items from the plastic film body.

[0009] Optionally, the corrugated paperboard includes an inner paper fixed to one side of the inner wall of the plastic film body, and a corrugated paper body fixed to one side of the inner paper.

[0010] By adopting the above technical solution, the lining paper is boxboard, which can support the corrugated paper body, and the corrugated paper body can resist pressure and cushion the corrugated paper structure when it is impacted.

[0011] Optionally, a middle paper is fixedly provided on a side of the corrugated paper body facing away from the inner paper, and a honeycomb paper is fixedly provided on a side of the middle paper facing away from the middle paper.

[0012] By adopting the above technical solution, the middle paper can connect the corrugated paper body and the honeycomb paper, and the honeycomb paper can resist pressure and cushion the corrugated paperboard structure when it is impacted.

[0013] Optionally, a surface paper is fixedly provided on a side of the honeycomb paper facing away from the middle paper.

[0014] By adopting the above technical solution, the face paper can connect the honeycomb paper and the glass fiber mesh cloth.

[0015] Optionally, a glass fiber mesh cloth is fixedly provided between the side of the face paper facing away from the honeycomb paper and the inner wall of the plastic film body.

[0016] By adopting the above technical solution, the grid structure of the glass fiber mesh cloth can resist compression and buffer the corrugated cardboard structure when it is impacted.

[0017] Optionally, the plastic film body is filled with an inert gas.

[0018] By adopting the above technical solution, the plastic film body and the inert gas filled inside will form an air bag, which can cushion and protect the corrugated cardboard structure that is hit. When the plastic film body is ignited, the inert gas inside it will be released, which can have a certain flame retardant effect.

[0019] In summary, the present invention has at least one of the following beneficial effects:

[0020] 1. By wrapping the plastic film, the waterproof performance of the corrugated cardboard can be improved, making it difficult for the corrugated cardboard to be deformed by contact with water. The anti-slip protrusions can contact the packaged items to prevent the items from slipping, and can also separate the packaged items from the plastic film, so that the plastic film will not directly contact the packaged items, thereby making the plastic film less likely to be worn by the packaged items and extending the service life of the plastic film.

[0021] 2. Through the arrangement of components such as corrugated paper, honeycomb paper and glass fiber mesh cloth, the compression resistance and cushioning performance of the corrugated paperboard structure can be improved, so that the corrugated paperboard structure is not easily damaged after impact, and the plastic film body cooperates with the inert gas filled inside to form an air bag, which can cushion and protect the corrugated paperboard structure that is impacted. When the plastic film body is ignited, the inert gas inside it will be released, which can have a certain flame retardant effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is combined with Figure 1-3 The utility model is described in further detail.

[0027] Reference Figure 1 The utility model embodiment discloses a composite corrugated cardboard structure, including a corrugated cardboard 1, and a plastic film body 2 compositely wrapped on the outer wall of the corrugated cardboard 1 and used for waterproofing the corrugated cardboard 1. The plastic film body 2 is compositely glued to both sides of the outer wall of the corrugated cardboard 1, and the plastic film body 2 will form a plastic film cover to cover the corrugated cardboard 1, thereby waterproofing the corrugated cardboard 1. The plastic film cover can be made of high-strength and wear-resistant plastic film used in plastic greenhouses. The corrugated cardboard 1 and the plastic film body 2 and other components constitute a composite corrugated cardboard structure.

[0028] Reference Figure 1The side wall of the plastic film body 2 is provided with folding lines 21 for providing a deformation space for the plastic film body 2 after the corrugated cardboard structure is squeezed. When the corrugated cardboard structure is squeezed, the plastic film body 2 can be folded or stretched through the folding lines 21 to provide a deformation space for the plastic film body 2, so that the plastic film body 2 is not easily damaged when squeezed.

[0029] Reference Figure 1 A plurality of anti-skid protrusions 22 for preventing the packaged items from slipping and separating the plastic film body 2 and the packaged items are fixedly provided on both sides of the outer wall of the plastic film body 2. The anti-skid protrusions 22 can be existing anti-skid silicone blocks with anti-skid function. The anti-skid protrusions 22 can directly contact the packaged items to prevent the items from slipping. At the same time, they can separate the packaged items from the plastic film body 2, so that the plastic film body 2 will not directly contact the packaged items, thereby making the plastic film body 2 not easily worn by the packaged items and extending the service life of the plastic film body 2.

[0030] Reference Figure 1 The plastic film body 2 is filled with an inert gas 23. The plastic film body 2 and the inert gas 23 filled therein will form an air bag, which can cushion and protect the corrugated cardboard structure that is hit. When the plastic film body 2 and the corrugated cardboard 1 are ignited, the inert gas 23 inside them will be released. Since the inert gas 23 has the advantages of flame retardancy, the inert gas 23 in the corrugated cardboard structure can have a certain flame retardant effect after being released.

[0031] Reference Figure 1-2 The corrugated paperboard 1 includes an inner paper 11 fixed on one side of the inner wall of the plastic film body 2, and a corrugated paper body 12 fixed on one side of the inner paper 11. The inner paper 11 is a boxboard and can support the corrugated paper body 12. The corrugated paper body 12 is an existing corrugated paper and has the advantages of good compression resistance and buffering effect.

[0032] Reference Figure 1-3 A middle paper 13 is fixedly provided on the side of the corrugated paper body 12 away from the inner paper 11, and a honeycomb paper 14 is fixedly provided on the side of the middle paper 13 away from the middle paper 13. The middle paper 13 can connect the corrugated paper body 12 and the honeycomb paper 14. The honeycomb paper 14 is an existing honeycomb paper, which has the advantages of impact resistance, pressure resistance, not easy to deform and good buffering effect.

[0033] Reference Figure 1-2 A face paper 15 is fixedly provided on the side of the honeycomb paper 14 facing away from the middle paper 13, and the middle paper 13 and the face paper 15 are also box paperboards.

[0034] Reference Figure 1-2A glass fiber mesh cloth 16 is fixed between the side of the face paper 15 facing away from the honeycomb paper 14 and the inner wall of the plastic film body 2. The face paper 15 can connect the honeycomb paper 14 and the glass fiber mesh cloth 16. The glass fiber mesh cloth 16 is an existing glass fiber mesh cloth and has the advantages of compression resistance, tensile resistance and waterproofness.

[0035] The implementation principle of a composite corrugated paperboard structure of the utility model embodiment is:

[0036] When in use, the corrugated paper body 12, the honeycomb paper 14 and the glass fiber mesh cloth 16 can improve the compression resistance and buffering performance of the corrugated paperboard structure, so that the corrugated paperboard structure is not easily damaged after being impacted, and the plastic film body 2 cooperates with the inert gas 23 filled inside to form an air bag, which can buffer and protect the corrugated paperboard structure that is impacted. When the plastic film body 2 is ignited, the inert gas 23 inside it will be released, which can play a certain flame retardant effect;

[0037] The plastic film body 2 on the outside of the corrugated paperboard 1 forms a plastic film cover to cover the corrugated paperboard 1, thereby providing waterproof protection for the corrugated paperboard 1, so that the corrugated paperboard 1 is not easily deformed by contact with water. When the corrugated paperboard structure is squeezed, the plastic film body 2 can be folded or stretched through the folding lines 21 to provide a space for the plastic film body 2 to deform, so that the plastic film body 2 is not easily damaged when squeezed.

[0038] The anti-skid protrusions 22 can directly contact the packaged items to prevent the items from slipping. At the same time, they can separate the packaged items from the plastic film body 2 so that the plastic film body 2 does not directly contact the packaged items, thereby making the plastic film body 2 less likely to be worn by the packaged items and extending the service life of the plastic film body 2.

[0039] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
