Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paper boxes, and in particular relates to a high-strength environmentally friendly corrugated paperboard for packaging. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly known as "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "box board", "box board"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] Items made of corrugated cardboard have gradually become frequently used in people's daily lives. Most corrugated cardboards are used for product packaging. However, the existing corrugated cardboards have poor strength, are easily damaged during use, and are inconvenient to use during packaging. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a high-strength environmentally friendly corrugated paperboard for packaging.

[0005] To achieve the above-mentioned purpose, the utility model proposes a high-strength environmentally friendly corrugated cardboard for packaging, comprising a first cardboard, a second cardboard is movably installed on one side of the first cardboard, a first foam board is fixedly bonded to both sides of the first cardboard, a second foam board is fixedly bonded to both sides of the second cardboard, multiple layers of corrugated paper are fixedly installed inside the first cardboard and the second cardboard, arc-shaped paper flutes are fixedly installed on the inner side of the corrugated paper, and a middle partition is fixedly bonded inside the corrugated paper.

[0006] Preferably, a card slot is provided inside the first foam board, and a plurality of card blocks are fixedly mounted on the side of the second foam board.

[0007] Preferably, the card block is movably embedded in the card slot, and the outer dimension of the card slot is larger than the inner dimension.

[0008] Preferably, one side of the first paperboard is embedded and adhered to the inside of the first foam board, and one side of the second paperboard is fixedly embedded and adhered to the inside of the second foam board.

[0009] Preferably, middle paper is fixedly installed between the corrugated papers, face paper is fixedly adhered to the upper end surface of the corrugated papers, and inner paper is fixedly adhered to the lower end surface of the corrugated papers.

[0010] Preferably, a honeycomb groove is fixedly adhered to the interior of the middle partition, and a through groove is fixedly opened in the interior of the middle partition.

[0011] Preferably, both sides of the arc-shaped paper flutes are fixedly bonded to the inside of the corrugated paper, and the outer side surface of the face paper and the inner side surface of the lining paper are both fixedly bonded with a reinforcing film.

[0012] The high-strength environmentally friendly corrugated paperboard for packaging proposed by the utility model can bring the following beneficial effects:

[0013] 1. The utility model arranges double-layer corrugated paperboard, and double-layer corrugations are installed inside the paperboard. Arc-shaped supporting paper flutes are also installed inside the corrugations. The two ends of the arc-shaped paper flutes are adhered to the inner side of the corrugations. When the corrugations are squeezed and deformed in use, the arc-shaped paper flutes support the corrugations, thereby increasing the supporting strength of the corrugations. The double-layer corrugations are arranged to effectively improve the strength of the carton. The carton is made of paper as a whole, can be degraded and recycled, reduces pollution to the environment, and is more environmentally friendly.

[0014] 2. The utility model provides a corrugated paper box that is easy to use. When the corrugated paper box is used as packaging supplies, it can be spliced ​​with multiple first paper boards and second paper boards. Foam boards are fixedly adhered to both sides of the first paper board and the second paper board. A card slot is opened on the side of the first foam board, and a card block is fixedly installed on the side of the second foam board. When installing, the card block is embedded in the card slot, and at the same time, damage to the carton caused by folding during multiple uses is reduced. Grooves are fixedly installed on both sides of the lower end of the carton, which is convenient for lifting the carton as a whole when in use, which is more convenient.
