DETAILED DESCRIPTION

[0016] like Figure 1It is a structural schematic diagram of the utility model, a pressure-resistant and shock-absorbing reusable paperboard, characterized in that, from the outside to the inside, there are an outer waterproof layer 1, an outer paperboard layer 2, a pressure-resistant layer 3, a central partition 4, an airbag layer 5, an inner paperboard layer 6 and an inner waterproof layer 7; the outer waterproof layer 1 is sprayed on the outside of the outer paperboard layer 2, and the inner waterproof layer 7 is sprayed on the inside of the inner paperboard layer 6; the outer paperboard layer 2, the pressure-resistant layer 3, the central partition 4, the airbag layer 5, and the inner paperboard layer 6 are arranged in parallel and fixedly adhered to each other, wherein the airbag layer 5 includes a plurality of groups of hollow triangular prisms 8 and airbag strips 9, and airbag strips 9 are provided in the center of each group of hollow triangular prisms 8 and between two adjacent groups of hollow triangular prisms 8; the pressure-resistant layer 3 is composed of a plurality of groups of elastic components 10.

[0017] Specifically, the outer waterproof layer 1 and the inner waterproof layer 7 prevent the cardboard from getting damp, so as to achieve the purpose of repeated use. Moreover, according to the design of the pressure-resistant layer 3 and the airbag layer 5, the external pressure is decomposed to improve the pressure resistance, which can effectively protect the goods from damage during transportation. At the same time, it has a shock-absorbing function, reducing the risk of packaging damage caused by external force impact.

[0018] According to another embodiment of the utility model, the hollow triangular prisms 8 are further arranged in parallel in the longitudinal direction, and the contact surfaces with the central partition 4 and the inner paperboard layer 6 and the contact surfaces between the hollow triangular prisms 8 are all adhered to each other.

[0019] According to another embodiment of the utility model, the airbag strip 9 is a cylinder with a circular cross section.

[0020] Specifically, the hollow triangular prism 8 increases internal stability to prevent damage to the goods inside the cardboard due to squeezing, wherein the airbag strip 9 can alleviate external impact force and play a shock-absorbing role, thereby reducing the risk of packaging damage caused by external impact.

[0021] According to another embodiment of the utility model, the gap between the elastic components 10 is further filled with pearl cotton 13, one side of which is fixed on the outer silicone pad 11, and the other side is fixed on the inner silicone pad 12, the outer silicone pad 11 is adhered to the inner wall of the outer cardboard layer 2, and the inner silicone pad 12 is adhered to one side of the central partition 4.
