The bottom of the box bears the weight of the goods, so firmness is emphasized.In addition, when filling goods, whether it is machine filling or manual filling, simple structure and easy assembly are the basic requirements.There are mainly the following ways at the bottom of the tubular packaging box.

1.Plug-in self-locking bottom

Using the four rocking wing parts at the bottom of the tubular packaging box, they are designed to have a bite relationship with each other.This kind of bite is completed in two steps: “Don't” and “insert”. It is easy to assemble and has a certain load-bearing capacity. It is more commonly used in tubular packaging boxes.

2.Automatic bottom lock

The automatic bottom-locking packaging box adopts a pre-adhesive processing method, but it can still be flattened after bonding. As long as the box body is opened when used, the bottom of the box will automatically return to the locked state. It is extremely convenient to use, saves time and labor, and has good load-bearing capacity. It is suitable for automated production. Generally, this design structure is used for packaging designs that carry high-weight items.

3.Rocker cover, double socket type back cover

The structure is exactly the same as the sliding lid plug-in lid. This design structure is easy to use, but the load-bearing capacity is weak. It is usually suitable for packaging small or light-weight commodities such as food, stationery, toothpaste, etc. It is a more common packaging box design structure.

4.Inter-wall back cover type

The back cover structure of the inter-wall is to design the four rocking wings of the tubular packaging box into a structure with the function of inter-wall. After assembly, an inter-wall will be formed inside the box body, which can effectively separate and fix the goods and play a good protective role.The inner wall is integrated with the box, which can effectively save costs, and the compressive strength of this box structure is high.

5.Other evolutionary structures

According to the above commonly used basic packaging box structure model, some other structural forms can also be evolved through design.
