Bulk bags often referred to as flexible intermediate bulk containers (FIBCs), provide a more economic and affordable answer for material handling, storing, and transportation. Do you need a bulk bag? How do you determine the size you need? Calculating the weight of a FIBC bag seems like a task. Bulk bags come in a range of sizes and dimensions and FIBC (Bulk Bag) specifications. Your bulk bag must be the right size for you, your material, and finally, your customer. Discover how FIBC bag weight calculation is done.

Take a note of Material or Product
To inform you about this point, let's take help of an example. Which weighs more – one kilogram of cotton, or one kilogram of gold? If you said gold, you would have answered the question incorrectly. No matter how you look at it, one Kg is one Kg. It doesn’t matter if it’s gold or cotton. They both weigh the same.

Low-Density Materials
The easiest way to determine if you have a low-density or high-density material is to determine its weight. It’s relatively easy to say that ...
... you need a more oversized bag to carry one kilogram cottom than you do one kilogram of gold bar. You can probably have a single Kg of gold bar in your bare hands. However, one Kg of cotton requires a bag so big that it may need a truck to transport. Low-density materials weigh less, allowing you to choose a larger pack. This is how to calculate the weight of FIBC bag

High-Density Materials
High-density materials weigh higher. Therefore, your bag must be smaller. We’re not talking about any regular packaging boxes. These are still bulk bags. If you have a hefty product, you may want to consider a smaller bag. That way, the bag's volume can handle more pressure per square inch without bursting or breaking.

Take note of the Minimum and Maximum Dimensions
When you determine your bag size, remember that, when you transport it, the only part of the bag that is in contact with your carrier is the base of the bag. However, don’t neglect the fact that these are flexible bags. An adequately filled bag will have a belly at the sides and increase your dimensions by up to 20 percent. You can prevent this – at an increased cost – by purchasing bags with internal baffles.

The Minimum Size
For this, you have to determine the minimum size of your carrier. In other words, where are you going to store the bag? How are you going to transport the bag? The only part of the bag that touches the carrier is the base. To ensure that your bags can fit inside your carrier, your bags' width or length (whichever is longer) must be shorter than the capacity that your carrier can handle. For example, if the tractor-trailer's internal width is 96 inches and you plan on putting two bags side-by-side, then the width of your bags must be shorter than 48 inches. If you put two 48 inch bags side-by-side, you will get 96 inches. Anything longer than that and your bulk bag and its dimensions will not fit in the trailer.

The Maximum Size
Now that we have the minimum size, we can use this to determine the maximum size. Take the figure for the width and add it to the value for the length. Multiply this number by two and divide by pi (3.14159), and you will have the diameter of the filled bag.
