Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboards, and more specifically, to compression-resistant corrugated paperboards. Background Art

[0002] Corrugated cardboard packaging boxes are very common in our daily life and are often used in the packaging and transportation of goods. Corrugated paper is a plate-like material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into single corrugated cardboard and double corrugated cardboard. Compression-resistant corrugated cardboard is a kind of corrugated cardboard with compression-resistant effect.

[0003] A Chinese patent with patent application number CN202322314406.4 discloses a compression-resistant corrugated cardboard, including a corrugated cardboard assembly and a sealing plate. The corrugated cardboard assembly includes an outer cardboard and a core paper sandwich. The outer cardboard and the core paper sandwich are glued together. The sealing plates are arranged around the corrugated cardboard assembly. There are four sealing plates, and the four sealing plates are connected end to end. The compression-resistant corrugated cardboard is sealed by sealing plates arranged around the corrugated cardboard assembly to prevent moisture or water in the outside air from entering the inside of the corrugated cardboard, thereby enhancing the moisture-proof and waterproof properties of the device, and further improving the compression resistance of the corrugated cardboard. The waterproof properties of the outer cardboard and the sealing plate are enhanced by a waterproof layer arranged on the outside of the outer cardboard and the sealing plate. The waterproof layer is protected by an anti-wear layer arranged on the outside of the waterproof layer to prevent the waterproof layer from being worn and damaged.

[0004] Then, combined with the drawings in its specification, it can be seen that the compression-resistant corrugated cardboard uses S-shaped corrugated cardboard inside to achieve the function of supporting compression resistance. When external pressure squeezes the internal S-shaped corrugated cardboard, it is easy for the S-shaped corrugated cardboard and the internal layers to be damaged due to external pressure, thereby causing the carton structure to be destroyed, affecting the supporting compressive strength, and thus affecting the service life.
