Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper, in particular to an impact-resistant corrugated paperboard structure. Background Art

[0002] The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

[0003] The Chinese authorization announcement number is CN218343012 U, and the authorization announcement date is January 20, 2023. It discloses a new type of corrugated cardboard with a double corrugated paper core, including a first corrugated core layer, a first thermal insulation layer is fixedly bonded on the lower surface of the first corrugated core layer, an inner paper layer is fixedly arranged on the lower surface of the first thermal insulation layer, and a soft silicone shock-absorbing layer is fixedly arranged on the lower surface of the inner paper layer; a second thermal insulation layer is fixedly bonded on the upper surface of the first corrugated core layer, an aluminum foil insulation layer is fixedly bonded on the upper surface of the second thermal insulation layer, a second corrugated core layer is fixedly bonded on the upper surface of the aluminum foil insulation layer, a PET film waterproof layer is fixedly bonded on the upper surface of the second corrugated core layer, and an outer paper layer is fixedly bonded on the upper surface of the PET film waterproof layer. The defects of this existing technology are: the first corrugated core layer and the second corrugated core layer are only simple wavy corrugated core layer structures. Through a predetermined number of usage frequency tests, it is known that the first corrugated core layer and the second corrugated core layer are prone to deformation, which directly reduces their anti-seismic, buffering and impact resistance functions. In view of this situation, improvement is urgently needed. Utility Model Content
