Description

Technical Field

[0002] 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 pressure from a plane, is elastic, and has a good cushioning effect. It can be made into pads or containers of various shapes and sizes as needed, which is simpler and faster than plastic cushioning materials. It is less affected by temperature, has good light-shielding properties, does not deteriorate under light, and is generally less affected by humidity. However, it is not suitable for long-term use in an environment with high humidity, which will affect its strength.

[0003] When optimizing existing green, recyclable and easily degradable corrugated cardboard, most of them are reflected in the aspect of preventing the inner side of the corrugated cardboard from getting damp and deforming. For example, the Chinese utility model patent with patent number CN213675902U discloses "Recyclable High-Strength Corrugated Cardboard", which includes an outer cardboard, an inner cardboard is provided on the inner side of the outer cardboard, and a nameplate is provided on the front side of the outer cardboard, a moisture discharge hole is provided at the bottom of the front side of the outer cardboard, a decorative strip is provided between the outer cardboard and the inner cardboard, and a trapezoidal cardboard is adhered between the outer cardboard and the inner cardboard, a round paper tube is inserted into the side of the trapezoidal cardboard, and flame-retardant ceramic particles are provided on the inner side of the round paper tube.

[0004] Although the green, recyclable and biodegradable corrugated cardboard mentioned above has certain advantages in preventing the inner side of the corrugated cardboard from getting damp and deforming, it still has certain disadvantages:

[0005] 1. If Figure 6 As shown, a trapezoidal cardboard is provided between the outer cardboard and the inner cardboard, and a round paper tube is inserted into the through hole opened in the side of the trapezoidal cardboard, so that the overall strength of the corrugated cardboard can be improved, and the flame-retardant ceramic particles provided on the inner side of the round paper tube can block the fire and avoid damage to the internal objects of the corrugated cardboard. Elastic strips and moisture-proof layers are provided between the trapezoidal cardboard and the inner cardboard and the outer cardboard, respectively, so as to avoid moisture and deformation of the inner side of the corrugated cardboard. However, the green, recyclable and degradable corrugated cardboard mentioned above has the inner cardboard on the inner side, which makes it inconvenient for the carton made of the degradable corrugated cardboard to directly contact with food and is not convenient for keeping food warm, which makes it difficult to improve the practicality of the degradable corrugated cardboard, and the outer side of the green, recyclable and degradable corrugated cardboard mentioned above has the outer cardboard, which makes the outer side of the degradable corrugated cardboard not wear-resistant enough, making it difficult to improve the service life of the recyclable and degradable corrugated cardboard.

[0006] 2. The green, recyclable and easily degradable corrugated paperboard mentioned above needs to be bonded with adhesive during assembly, which makes it difficult to improve assembly efficiency. Utility Model Content
