Referring to Figures 1-3, an insulating corrugated paper box includes a paper box body 1, and the paper box body 1 includes a corrugated paper body 6. The upper and lower sides of the corrugated paper body 6 are respectively provided with top noodle paper 5 and bottom noodle paper 7. The top of the top noodle paper 5 is provided with a buffer layer 4, and the top of the buffer layer 4 and the bottom of the bottom noodle paper 7 are provided with a waterproof layer 3 and a fireproof layer 2. The two fireproof layers 2 are respectively arranged at the top and the bottom. By arranging the buffer layer 4, the effect of buffering and protecting the packaged object can be achieved. By arranging the waterproof layer 3 and the fireproof layer 2, the waterproof and fireproof functions can be achieved. The noodle paper and the corrugated paper body 6 together constitute the paper box body 1, which enhances the strength of the paper box during use and reduces deformation.

Furthermore, the corrugated paper body 6 includes a first corrugated paper 61 and a second corrugated paper 62 . The first corrugated paper 61 is arranged in a wavy structure, and the second corrugated paper 62 is evenly arranged on the surface of the first corrugated paper 61 .

Furthermore, gaps are provided between the first corrugated paper 61, the second corrugated paper 62 and the noodle paper, and thermal insulation foam particles 8 are provided inside the gaps. By filling the thermal insulation foam particles 8 in the gaps between the first corrugated paper 61 and the second corrugated paper 62, the thermal insulation function can be achieved, and since the internal gaps are filled, the strength of the paper box is further enhanced, and the gaps are formed evenly, and each gap is a separate closed space. Therefore, even when the paper box body 1 is cut, the thermal insulation foam particles 8 will only appear at the cut position, but the problem of thermal insulation foam particles 8 coming out will not occur as a whole.

Furthermore, the waterproof layer 3 is a plastic film, and the waterproof layer 3 is adhered to the surface of the plastic film. The plastic film itself has a certain elasticity, so the waterproof effect is strong, and the waterproof layer 3 will not be broken due to the bending of the paper box body 1.

Furthermore, the buffer layer 4 is a flame retardant sponge. By providing the flame retardant sponge, on the one hand, it plays a buffering function, and on the other hand, the fireproof material synthesized by the flame retardant inside the flame retardant sponge can further play a fireproofing function.

Furthermore, the paper box body 1 includes a box cover 11, a box body 12 and a thickened bottom plate 13. The box body 12 is open at the top, the box cover 11 is rotatably connected to the top of the box body 12, and the thickened bottom plate 13 is arranged at the bottom of the box body 12. The thickened bottom plate 13 arranged at the bottom can support the box body 12, and can also play an isolation role, further playing a heat preservation function.

In summary, by setting the buffer layer 4, the effect of buffering and protecting the packaged object can be achieved, and by setting the waterproof layer 3 and the fireproof layer 2, the waterproof and fireproof functions can be achieved. The noodle paper and the corrugated paper body 6 together constitute the paper box body 1, which enhances the strength of the paper box during use and reduces deformation. By filling the gap between the first corrugated paper 61 and the second corrugated paper 62 with thermal insulation foam particles 8, the thermal insulation function can be achieved, and because the internal gap is filled, the strength of the paper box is further enhanced, and the gap is formed evenly, and each gap is a separate closed space, so even when the paper box body 1 is cut, there will only be The thermal insulation foam particles 8 will pop out at the cut position, but the problem of thermal insulation foam particles 8 popping out will not occur as a whole. The waterproof layer 3 is glued to the surface with a plastic film. The plastic film itself has a certain elasticity, so the waterproof effect is strong, and the waterproof layer 3 will not be broken due to the bending of the paper box body 1. By setting the flame retardant sponge, on the one hand, it has a buffer function, and on the other hand, the fireproof material synthesized by the flame retardant inside the flame retardant sponge can further play a fireproof function. The thickened bottom plate 13 set at the bottom can support the box body 12, and can also play an isolation role, and further play a heat preservation function.
