As a container with a wide range of applications, it is important to learn how to correctly calculate the capacity of a single FIBC. First of all, we have to consider the raw materials used in weaving FIBC, generally FIBC is woven from polypropylene or polyethylene, because material reasons may cause the internal and external deformation of FIBC, which also means that the basic capacity value may be biased when calculating, that is, the amount of materials loaded during the actual loading may also be biased. Secondly, it is necessary to pay attention to the unit used to calculate the capacity, usually the capacity of FIBC is calculated in cubic meters, but some companies will also use cubic feet, which needs to pay attention to the conversion of calculation units in practical application to avoid economic losses and conflicts in the later period. Then, it is also necessary to determine the size of the FIBC, and the capacity of the general FIBC is calculated according to the length, width and height (capacity = length * width * height). It is important to note here that using the standard FIBC bag weight calculation method to determine the capacity of the material is not equal to the capacity loaded into the FIBC, as it is also affected by other factors:

1. Type of feed port. For example, an open pocket has more flexibility in terms of capacity, but when there is a nozzle at the top of the bag, it may cause the original space to load materials to be squeezed, making the load less than calculated.

2. Round. Due to the soft material of the FIBC bag, this may result in rounded corners or reinforced corner plates at the corners of the bag, reducing its capacity.

3. Material density. The higher the material density, the smaller the packaging capacity of FIBC, and the larger the vice versa. This is an important issue to consider.

4. Hanging rings. In order to facilitate forklift transport, FIBC almost always designs the lifting ring, because the extra gap between the bag and the lifting ring needs to be left (the gap is equal to the height of the bag and the lifting ring), so the length, width and height of the lifting ring is an important factor affecting the capacity of the bag.

To sum up, you can directly use the FIBC calculator to ensure that the FIBC basic capacity you choose is accurate to meet your needs, and then you need to consider other factors that affect the FIBC capacity (as listed above), and finally make a wise choice to really reduce unnecessary waste and mistakes when purchasing.
