Description

Technical Field

[0001] The utility model relates to the technical field of composite boards, in particular to a multi-layer composite board. Background Art

[0002] Corrugated cardboard is widely used in packaging due to its strength. The cardboard used in packaging boxes primarily consists of corrugated paper, face paper, and lining paper. The corrugated paper is typically constructed in two or three layers, separated by a core paper. After gluing together, these layers form what are known as five- or seven-layer boards. While the presence of the corrugations within the board provides excellent strength, its cushioning properties are significantly poor, making it susceptible to damage during impacts. This has become a major concern in its use. However, this composite corrugated board has certain drawbacks, including its simple structure, which needs improvement in impact and compression resistance, and its lack of waterproofing.
