Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboards, in particular to a high-strength anti-deformation corrugated paperboard. Background Art

[0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of boxboard (also called boxboard), and has good elasticity and extensibility. It is mainly used to make cartons, the sandwich of cartons, and other packaging materials for fragile goods. The cost is also relatively cheap.

[0003] Please refer to the high-strength anti-deformation corrugated paperboard with announcement number CN212949510U. The patent states that "the current corrugated paper is easy to damage, has weak pressure resistance, is easy to change, has weak bending resistance, is not strong enough to protect large and heavy objects, and is not practical." The patent increases the pressure resistance and buffering capacity of the entire paperboard through pressure-resistant paper tubes and buffer grids, and the pressure-resistant paper tubes improve the longitudinal bending resistance of the paperboard. The connecting rods improve the transverse bending resistance of the paperboard, thereby achieving high-strength anti-deformation ability of the paperboard.

[0004] However, although the above patent can improve the bending and compression resistance of the paperboard, it can only resist bending force. The connecting rod passes through the compression-resistant paper tube. When the paperboard is subjected to external shear force, the connecting rod will still be deformed, and the deformed connecting rod cannot return to its original state. It is not only easy to cause damage to the compression-resistant paper tube, but also the deformation of the connecting rod will affect the overall shape of the paperboard, thereby causing the paperboard to be unable to continue to be used subsequently; in view of this, the present application proposes a high-strength anti-deformation corrugated paperboard.
