Moisture-proof corrugated paper board

Abstract

The invention discloses a moisture-proof corrugated paper board. The moisture-proof corrugated paper board comprises first kraft paper and second kraft paper, wherein upper-layer paper is arranged onthe bottom of the first kraft paper; a first adhesive is arranged between the upper-layer paper and the first kraft paper; lower-layer paper is arranged on the top of the second kraft paper; a secondadhesive is arranged between the lower-layer paper and the second kraft paper; supporting strips are arranged between the upper-layer paper and the lower-layer paper; the top ends of the supporting strips adhere to the bottom of the upper-layer paper; and the bottom ends of the supporting strips adhere to the top of the lower-layer paper. By arrangement of the first kraft paper and the second kraft paper which are made from a composite kraft paper material, moisture in an environment can be effectively prevented from intruding into the corrugated paper board, moreover, a dehumidifying tube isarranged between the first kraft paper and the second kraft paper, and is filled with a dehumidifying agent, moisture in the corrugated paper board can be removed, the inner layer of the paper board can be favorably protected against being wetted, and the service life of the paper board is prolonged.

Description

technical field [0001] The invention relates to the field of corrugated paper processing and production, in particular to a moisture-proof corrugated board. Background technique [0002] Corrugated cardboard is a multi-layer bonded body. It is composed of at least one layer of corrugated core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during handling. The current corrugated cardboard The base layer paper needs to be bonded with glue, and the moisture contained in the glue will remain in the corrugated cardboard, and the moisture inside the corrugated cardboard is not easy to escape. Dehumidification of the corrugated cardboard has always been a headache for people. However, in the wet or rainy and snowy season, the moisture from the outside is more likely to enter the interior of the corrugated paper, seriously affecting the performance of the corrugated paper and wasting resources. [0003] Therefore,...

[0002] Corrugated cardboard is a multi-layer bonded body. It is composed of at least one layer of corrugated core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during handling. The current corrugated cardboard The base layer paper needs to be bonded with glue, and the moisture contained in the glue will remain in the corrugated cardboard, and the moisture inside the corrugated cardboard is not easy to escape. Dehumidification of corrugated cardboard has always been a headache for people.

However, in the wet or rainy and snowy season, the moisture from the outside is more likely to enter the interior of the corrugated paper, which seriously affects the performance of the corrugated paper and wastes resources.
