Embodiment approach

[0031] As an embodiment of the present invention, the lower end of the face paper layer 2 in the first core board 4 is bonded with an elastic column 41, and the elastic column 41 is arranged in the front and rear directions, and the outer surface of the elastic column 41 is in contact with the first The inner surfaces of the core board 4 are in conflict. Because the cushioning performance of the first core plate 4 is relatively poor, it is difficult to recover when it is deformed due to excessive impact. Therefore, by arranging the elastic column 41, the concave deformation to the inside can be restricted when it is stressed, and the cushioning performance is improved, so that The corrugated cardboard can be quickly restored and buffered for multiple times to improve the practicability of the corrugated cardboard, and the first core board 4 can be restored under the action of the elastic column 41 after the impact, avoiding the influence of the first core board 4 not being rest...

Abstract

The invention relates to the technical field of corrugated boards, and in particular, relates to a damp-proof anti-extrusion corrugated board and carton, wherein the damp-proof anti-extrusion corrugated board comprises a waterproof layer, a surface paper layer and an inner paper layer which are sequentially arranged from top to bottom; the waterproof layer is a polyvinyl chloride film and is adhered to the upper end of the surface paper layer through a waterproof adhesive; a corrugated core layer is arranged between the surface paper layer and the inner paper layer; the corrugated core layer comprises a plurality of first core plates which are bonded to the lower end of the surface paper layer at intervals and a plurality of second core plates which are bonded to the upper end of the innerpaper layer at intervals, the first core plates and the second core plates are arranged in a staggered mode, and the two sides of the lower portions of the first core plates are bonded to the corresponding second core plates on the two sides respectively. Through the arrangement of the first core plates and the second core plates, the corrugated board can have good deformation resistance and impact resistance at different positions under the effect of keeping good structural strength, and thus the corrugated board can adapt to different impacts in the carrying process.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard, in particular to a moisture-proof and extrusion-resistant corrugated cardboard and a carton. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and a layer Cardboard (also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand bumps and falls during handling. The actual performance of a corrugated box depends on three factors: the properties of the medium and paperboard and the construction of the box itself. [0003] The corrugated corrugated corrugated cardboard is like connected arched doors, which are arranged in a row with each other and support each other to form a triangular structure, which has good mechanical strength, can...
