Description

Technical Field

[0001] The utility model relates to the technical field of kraft paper packaging boxes, in particular to a foldable kraft paper packaging box. Background Art

[0002] As an indispensable part of modern logistics, packaging cartons bear the important responsibilities of containing, protecting products and being aesthetically pleasing. They are the most widely used packaging products. Depending on the materials used, there are corrugated cartons, kraft cartons, etc., with various specifications and models, and the colors and feel of various papers are different.

[0003] According to the search, Chinese patent literature, announcement number: CN216709949U, discloses a kraft paper folding packaging box. The kraft paper folding packaging box proposed by the utility model is integrally formed. When packaging items, it has good stability. In the production folding and forming process, there is only one piece of kraft paper, and the installation process is simple. The folding plate forms a buffer support part between the bottom plate and the supporting plate. When the items are subjected to external force, the folding plate has a buffering effect on the items and protects the items from damage. However, the device still has defects during use. Since the packaging box is made of kraft paper, it is easy to cause the box to tear when squeezed during transportation, so that the goods in the packaging box fall. The overall strength of the box is low, and since the bottom of the packaging box is directly in contact with the ground, it is inconvenient for personnel to lift it, and it is also inconvenient for forklifts and other equipment to carry it.
