All About Product Density

All About Product Density

There is a lot of misinformation about FIBCs on the internet. If you’ve read our blog in the past, you probably know this as we’ve talked about it before. However, we feel it’s important to bring it up in the context product density as there is a lot of bad info regarding this topic. Hopefully this post will help address some of that and set the record straight.


How to Find Product Density (hint: you don’t need to calculate product density)

This is a common question we find out there on the web: “how do I calculate product density?”. Now, we are pretty sure there is a way out there to ‘calculate’ product density if you have the right equipment, materials available, and expertise. Thankfully however, there is a much easier way to find the bulk density of your product: a handy product weight guide.

You can find these on the web if you look hard enough but let us save you some time here. Download our product weight guide and calculator by clicking here. We’ve not only included a guide that shows the density of hundreds of common products packed into FIBCs but have also included a calculator that will assist in finding the right bulk bag for your product.


Finding the Right Bulk Bag

Finding the right bag isn’t always as simple as finding a bag that has the right dimensions. More important than dimensions are construction type (check out our FIBC construction page for more information on construction types) and SWL (safe working load).  To make sure the bag you’re purchasing not only meets your needs in terms of dimensions but can also handle the weight of your product you’ll need to do some math.

We’ve included a very useful calculator in our product weight guide and calculator download. It’s pretty simple to use, and full instructions are included on the Thank You page that will display after you fill out the form. Just type in your product density, the dimensions of your bag, and the calculator will give you the filled weight of the FIBC. That will help you know just how much weight a bulk bag full of your specific product will weigh, allowing you to find an FIBC that has a SWL capacity to handle what you’re putting in it.

Safety and reliability are our top priorities. Each bag that we sell has a safe working load (SWL). To make sure the product you’re packing will not exceed the SWL of the bag you’re interested in, you’ll need to know the bulk density of the product you’re packing as well as the cubic foot capacity of the bag.
