Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated paperboard technical field, specifically a kind of multilayer pressure-resistant corrugated paperboard. BACKGROUND

[0002] Corrugated paperboard, also known as corrugated paperboard, is made of at least one layer of corrugated paper and one layer of boxboard paper (also known as boxboard), which has good elasticity and extensibility, and is mainly used for manufacturing paper boxes, paper box cores and other packaging materials for fragile goods, but is prone to deformation under external force and has weak compression resistance.

[0003] According to the patent with the announcement number CN220841774U, a multilayer pressure-resistant corrugated paperboard is disclosed, which has good compression resistance effect when the support frame and the core plate are combined. The corrugated paperboard is fixed between the faceplate and the core plate, and multiple support frames are fixed inside the corrugated paperboard. The buffer pad attached to the inside of the support frame is attached to both sides of the core plate. The material of the support frame is high-impact polystyrene, which is connected with rubber particles of micron size through grafting. When impacted, the tip stress of crack propagation is released by the relatively soft rubber particles, so it has good impact resistance. The support frame can support the shape of the corrugated paperboard, and the buffer pad fixed inside has good elasticity and impact resistance, which can absorb external impact force.

[0004] Based on the above search and existing technology, it is found that the above-mentioned patent has some defects. The simple corrugated paperboard supports the corrugated board and the core plate, which is not enough to provide sufficient support. When subjected to a large impact force, stress concentration may occur at the wave crest and wave trough, causing local deformation or damage, affecting the overall pressure resistance, and reducing the use efficiency of the multilayer pressure-resistant corrugated paperboard.
