The bottom of tubular packaging boxes mainly has the following types.
The bottom of the box bears the weight of the goods, so sturdiness is emphasized. Additionally, when filling the goods, whether by machine or by hand, a simple structure and easy assembly are basic requirements. There are mainly the following methods for the bottom of tubular packaging boxes.
The bottom of the box bears the weight of the goods, thus emphasizing sturdiness. Additionally, when filling goods, whether through machine filling or manual filling, a simple structure and easy assembly are basic requirements. The bottom of tubular packaging boxes mainly has the following methods.
1. Insert-type self-locking bottom
Utilizing the four rocking wing components at the bottom of the tubular packaging box, designed to interlock with each other. This interlocking is completed through two steps: "hook" and "insert", making assembly convenient and providing a certain load-bearing capacity, commonly used in tubular packaging boxes.
2. Automatic locking bottom
The automatic locking bottom packaging box uses a pre-adhesive processing method, but can still be flattened after adhesion. When in use, simply open the box body, and the bottom will automatically return to a locked state, making it extremely convenient, saving time and effort, and having good load-bearing capacity. It is suitable for automated production and is generally used for packaging designs that carry heavy items.
3. Rocking cover, double-insert back cover
The structure is completely the same as the sliding cover insert back cover. This design structure is easy to use, but has a weaker load-bearing capacity, usually suitable for packaging small or lightweight items such as food, stationery, and toothpaste, and is a common packaging box design structure.
4. Partition back cover type
The partition back cover structure designs the four rocking wings of the tubular packaging box to have a partition function. After assembly, a partition is formed inside the box body, effectively separating and securing the goods, providing good protection. The inner wall and the box body are integrated, which can effectively save costs, and this box body structure has a high compressive strength.
5. Other evolved structures
Based on the commonly used basic packaging box structure models above, some other structural forms can also be evolved through design.
