Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paperboard, and particularly relates to a waterproof corrugated paperboard. Background Art

[0002] As a widely used packaging material, corrugated paperboard plays an important role in the fields of logistics, warehousing, and commodity packaging due to its multi-layer bonding structure, high mechanical strength, and good buffering performance. This paperboard is usually composed of at least one layer of wavy core paper sandwiched between paperboard layers, and its overall performance is affected by the material properties of the core paper and paperboard, as well as the carton structure design. The wavy core paper design of corrugated paperboard not only improves the compressive and impact resistance of the paperboard but also provides a good buffering effect, effectively protecting the items inside the package from external impacts and squeezes. However, despite the excellent mechanical strength and buffering performance of corrugated paperboard, it still faces some challenges in practical applications.

[0003] Firstly, the existing corrugated paperboard has obvious deficiencies in waterproof performance. During transportation, storage, or use, once it encounters a humid environment or accidental splashing of water, moisture easily penetrates into the interior of the paperboard, causing the paperboard to become soft, deformed, or even damaged, thus threatening the safety and integrity of the items inside the package.

[0004] Secondly, the edge treatment of the existing corrugated paperboard is also an issue that cannot be ignored. Since the fiber structure at the edges of the paperboard is relatively loose, it is easy to absorb moisture and deform, resulting in poor waterproofness and structural strength at the edges. This not only affects the overall aesthetics of the paperboard but may also cause potential safety hazards such as water leakage and damage during use.

[0005] Therefore, it is very necessary to invent a waterproof corrugated paperboard. Content of the Utility Model

[0006] The purpose of the utility model is to provide a waterproof corrugated paperboard to solve the problems mentioned in the background art.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model provides a waterproof corrugated paperboard, which includes a wire mesh, a water barrier layer, corrugated boards, and a sealing edge. The two sides of the wire mesh are respectively fixed by adhesive with the water barrier layer. The other side of the water barrier layer is respectively fixed by adhesive with the corrugated boards, and the outer edge of the water barrier layer is fixed by adhesive on the outer edge of the corresponding corrugated board; the outer edges of the wire mesh and the water barrier layer are fixed by adhesive with the sealing edge; the outer sides of the corrugated boards are all fixed by adhesive with plastic sealing films.

[0009] Furthermore, the corrugated board includes a first side paper, a core paper, and a second side paper, wherein the first side paper is fixed to the outer side of the corresponding waterproof layer by gluing, wherein the other side of the first side paper is fixed to the core paper by gluing; the other side of the core paper is fixed to the second side paper by gluing; the outer edges of the first side paper, the core paper, and the second side paper are fixed to the corresponding waterproof layer by gluing. Such an arrangement can improve the overall cushioning performance of the corrugated board.

[0010] Furthermore, the wire mesh is a mesh structure woven from a number of steel wires, wherein both ends of some of the steel wires are bent upward by 90°, and both ends of the remaining steel wires are bent downward by 90°. Such an arrangement can waterproof the edge of the corrugated cardboard no matter how the corrugated cardboard is cut, and at the same time, can improve the overall structural strength of the corrugated cardboard.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] According to the arrangement of the utility model, when in use, the waterproof layer effectively prevents moisture from penetrating the corrugated cardboard, and during transportation, storage or use, even if it encounters a humid environment or is accidentally splashed with water, it can ensure that the inside of the corrugated cardboard remains dry, thereby protecting the items in the package from damage; secondly, the wire mesh not only provides additional support for the corrugated cardboard, but also significantly improves its overall structural strength, which makes the cardboard less likely to deform or break when subjected to external pressure, impact or extrusion, thereby extending its service life; in addition, after the corrugated cardboard is cut, the wire mesh can be bent accordingly, so that the waterproof layer is closely fitted to the outer edge of the corresponding corrugated board, thereby enhancing the waterproofness of the edge of the corrugated cardboard.
