The bottom structure of the container bag plays a vital role in its overall design, directly affecting the stability, load-bearing capacity, and reliability of the container bag during transportation and storage.
Generally speaking, the common structures of the bottom of the container bag are as follows. One is the flat bottom structure, which has a relatively flat bottom and is usually made of multiple layers of high-strength materials stacked and sewn together. The advantage of the flat bottom structure is that it can provide greater stability when stacking, especially when stacking on a relatively flat ground such as a warehouse, it is not easy to tilt or slip. At the same time, the flat bottom design also facilitates automated filling and sealing operations on the production line to improve production efficiency. However, after the container bag with a flat bottom structure is filled with goods, it may require greater friction to move during transportation due to the large contact area between the bottom and the ground, which may increase the difficulty of transportation.
Another common bottom structure is the conical bottom. The bottom of the conical bottom container bag is a gradually shrinking shape, similar to a funnel. The advantage of this structure is that when unloading operations are carried out, the goods can flow out more smoothly and reduce residues. Especially for some granular or powdery goods with good fluidity, the conical bottom can greatly improve the efficiency of unloading. In addition, the conical bottom container bag also has certain advantages in space utilization. When multiple container bags are stacked, the conical bottoms can be nested with each other to save storage space. However, the conical bottom container bag is relatively weak in stability and requires additional fixing measures during stacking and transportation to prevent tipping.
Another type is a bottom structure with ribs. The bottom of this container bag is usually sewn with some additional reinforcement materials, such as high-strength fiber belts or plastic plates, to enhance the load-bearing capacity of the bottom. The design of the ribs can effectively disperse the weight of the goods and reduce the local pressure on the bottom, thereby improving the overall durability of the container bag. The bottom structure with ribs is suitable for loading heavier goods or for multiple handling and stacking. However, the production cost of the container bag with this structure is relatively high, and more sophisticated processes are required during the design and manufacturing process to ensure that the ribs are installed firmly and reliably.
In short, the bottom structure of the container bag is varied, and each structure has its unique advantages and applicable scenarios. When choosing a container bag, it is necessary to comprehensively consider the characteristics of the bottom structure based on factors such as the specific type of goods, transportation requirements, and storage environment to ensure that the container bag can meet the actual use needs.
