Abstract

The invention relates to a double-layer waterproof corrugated carton which comprises a carton body. The carton body is made from double-layer corrugated paper. The corrugated paper comprises an inner carton board layer, an outer carton board layer, an inner corrugated layer and an outer corrugated layer. Waterproof films are attached to the two faces of the inner corrugated layer and the two faces of the outer corrugated layer respectively. A waterproof paper layer is arranged between the inner corrugated layer and the outer corrugated layer. The outer carton board layer is attached to the outer side of the outer corrugated layer. The inner carton board layer is attached to the inner side of the inner corrugated layer. By the adoption of the double-layer waterproof corrugated carton, liquid outside the carton body can be prevented from flowing into the carton body, liquid inside the carton body can be prevented from flowing out of the carton body, the waterproof effect is good, and the strength of double-layer corrugated paper is high.

Description

technical field [0001] The invention relates to a packing box, in particular to a waterproof double-layer corrugated paper box. Background technique [0002] As a common packaging carton, corrugated paper boxes have high mechanical strength and can withstand collisions and falls during transportation.
