Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, and in particular to a moisture-proof and anti-static coated corrugated cardboard. Background Technology

[0002] Corrugated cardboard is a material composed of multiple layers of paper, typically including one layer of corrugated paper (also called corrugated paper) and two layers of flat paper (usually the outer and inner layers), manufactured through pressing and bonding processes. It is widely used in the packaging industry, especially in transportation and storage, to protect goods from damage. Currently, corrugated cardboard is mostly used for packaging electronic products, precision instruments, and food. Electronic products are highly sensitive to static electricity; electrostatic discharge can cause circuit damage, data loss, or performance degradation. Static electricity can cause dust, particles, and other debris to adhere to the cardboard surface, potentially affecting the product's appearance and quality. Furthermore, electronic products and food require strong protective properties. If the transportation or storage environment is too humid, the cardboard will become weak after absorbing moisture, leading to a decrease in its compressive strength and potentially failing to effectively protect the contents. If moisture penetrates the contents, especially for moisture-sensitive goods (such as electronic products and food), it may cause damage or failure. Moisture penetration into the corrugated cardboard can cause it to swell, twist, and crack, affecting the packaging's shape and structure. Therefore, there is a need for a moisture-proof and anti-static coated corrugated cardboard. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a moisture-proof and anti-static coated corrugated cardboard.

The upper corrugated paper 21 is wavy, and the upper reinforcing plates 22 are located in the gaps of the upper corrugated paper 21 and are rectangular in shape.

To better protect packaged items under different environments, the bottom surface of the core paper 1 is provided with a lower corrugated paper 3. The bottom surface of the core paper 1 and the top surface of the lower corrugated paper 3 are fixedly connected. The lower corrugated paper 3 includes a lower corrugated paper 31 and multiple lower reinforcing plates 32. The lower corrugated paper 31 is wavy, and the lower reinforcing plates 32 are located in the gaps of the lower corrugated paper 31 and are rectangular. By setting the lower corrugated paper 31 and the lower reinforcing plates 32, the strength and compressive strength of the paperboard can be increased, which can ensure that the paperboard can better protect packaged items under different environments.

[0021] The top surface of the upper corrugated paper 2 is provided with a face paper 4, and the top surface of the upper corrugated paper 2 is fixedly connected to the bottom surface of the face paper 4.
