[0002] At present, corrugated cardboard is the most widely used packaging material. Corrugated paper itself has the characteristics of light weight, low cost, and easy processing. It can also buffer external impact during transportation and effectively protect the items in the corrugated box.

[0003] The sides of corrugated cardboard are often at a weak point. During use, the sides cannot be protected, and the hardness of the sides is insufficient. The corrugated paper is easily deformed under extrusion. The authorized patent number 201921787956.5 mentions that the cardboard is protected on the side by a door-shaped extruded strip. The snap-on method is obviously not enough for the use of corrugated boxes, and it is easy to cause falling off, lose side protection, and reduce the service life. In order to solve the above problems, we propose a laminated edge-sealed corrugated cardboard. Utility Model Content

[0008] Preferably, the upper snap-fit ​​corrugated strip is inserted into the upper gap between the cavity and the corrugated paper, and the lower snap-fit ​​corrugated strip is inserted into the lower gap between the cavity and the corrugated paper, in order to protect the side of the paperboard and strengthen the side of the paperboard.

[0009] Preferably, the upper clamping corrugated strip, the lower clamping corrugated strip and the corrugated paper are all in a V shape to ensure the overall strength of the paperboard.

[0010] Preferably, the outer walls of the box board and the box side panels are wrapped with a waterproof film to ensure the overall waterproofness of the paperboard.

[0011] Preferably, the interior of the cavity is filled with fireproof material, and the fireproof material is made of polyurethane foam to ensure the overall fire resistance of the paperboard.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] 1. The utility model provides a box side plate through the side wall of the box board paper, which ensures the stability of the side of the cardboard paper during use, thereby improving the service life and quality of the cardboard paper.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The utility model embodiment discloses a film-laminated edge-sealed corrugated paperboard.

[0023] The utility model provides Figure 1-3A laminated edge-sealed corrugated cardboard shown includes box board paper 1, a cavity 7 is opened inside the box board paper 1, and corrugated paper 2 is arranged inside the cavity 7, and box side panels 3 are arranged on both sides of the box board paper 1, and upper clamping corrugated strips 4 are arranged at the top of the inner wall of the box side panels 3, and the upper clamping corrugated strips 4 are evenly arranged in multiple groups, and lower clamping corrugated strips 6 are arranged at the bottom end of the inner wall of the box side panels 3, and the lower clamping corrugated strips 6 are evenly arranged in multiple groups. The box side panels 3 are arranged through the side walls of the box board paper 1, which will ensure the stability of the side of the cardboard during use during the use of the box board 1, thereby improving the service life and quality of the cardboard.

[0024] To protect the sides of the cardboard: Figure 1 , Figure 2 and Figure 3 As shown, the upper snap-fitting corrugated strip 4 is inserted into the upper gap between the cavity 7 and the corrugated paper 2, and the lower snap-fitting corrugated strip 6 is inserted into the lower gap between the cavity 7 and the corrugated paper 2. The upper snap-fitting corrugated strip 4 and the lower snap-fitting corrugated strip 6 will enter the gap between the corrugated paper and the cavity to be plugged into and correspond to each other, completing the docking of the box board 1 and the box side panel 3, while also ensuring the stability of the docking point and improving the strength of the side of the paperboard.

[0025] In order to ensure the stability of the cardboard: Figure 1 , Figure 2 and Figure 3 As shown, the upper and lower corrugated strips 4 and 6 and the corrugated paper 2 are all in a V shape. By forming a V shape between the upper and lower corrugated strips 4 and 6 and the corrugated paper 2, the V-shaped corrugated strips will form a triangle inside the paperboard, greatly improving the stability of the paperboard.

[0026] In order to ensure the overall waterproofness of the cardboard: Figure 2 As shown, the outer walls of the box board 1 and the box side panels 3 are wrapped with a waterproof film 5. The provision of the waterproof film 5 will greatly improve the overall waterproof performance of the paperboard.

[0027] In order to ensure the fire resistance of the cardboard: Figure 2 As shown, the interior of the cavity 7 is filled with fireproof material 8, and the fireproof material 8 is made of polyurethane foam. By filling the interior with fireproof material 8, a good flame retardant effect will be achieved, and a good flame retardant effect will be achieved when a fire occurs.

[0028] When working; when the side of the box board 1 is used, the upper snap-fit ​​corrugated strip 4 and the lower snap-fit ​​corrugated strip 6 provided on the inner wall of the box side panel 3 are respectively inserted into the interior of the cavity 7. At this time, the upper snap-fit ​​corrugated strip 4 will be inserted into the gap between the corrugated strip and the cavity 7. At this time, the upper snap-fit ​​corrugated strip 4 will be placed inside the cavity 7, and at the same time, the lower snap-fit ​​corrugated strip 6 will enter the gap between the corrugated paper 2 and the cavity 7, completing the fixed connection between the box board 1 and the box side panel 3. The upper snap-fit ​​corrugated strip 4, the lower snap-fit ​​corrugated strip 6 and the corrugated paper 2 They are all V-shaped, which will be beneficial to the stability of the box board paper 1 and the box side panel 3 when they are connected, and at the same time will reinforce the side of the carton and protect the side of the carton. The outside of the box board paper 1 and the box side panel 3 are wrapped with a waterproof film 5, which will form an efficient waterproof protection for the carton. At the same time, the cavity 7 is filled with fireproof material 8, which can have a flame retardant effect. It also helps to improve the strength of the carton body and greatly improve the service life of the box board. The design is simple and it is more practical corrugated paper 2.
