How to find the ideal FIBC bag for your products?

Flexible Intermediate Bulk Containers (FIBCs) are a fantastic bulk packaging option for each and every business all over the world. But, when it is not ideal for your product, it can turn out to be a nightmare; for the sole reason that for transporting certain goods you require a set of specifications that ensures safe transportation. 

Whether the FIBC bag is used for storing or transporting a dry product, food-grade products, or hazardous materials, it is always safe to have a customized FIBC bag for your industry. 

Introduce yourself to the FIBC bag calculator that helps you find the ideal bulk bag for your specific requirements. 

What is the FIBC bag calculator?

A bulk bag is defined by the metrics, that includes, height, weight, width, safe work loading (SWL), SF, GSM, and many more parameters. Whether you’re using it for transporting sand, gravel, animal feed or any other substance, all of the aforementioned parameters including some more, tells you whether your FIBC bag is compatible with your industry or not!

The process of selecting the right FIBC bag can be overwhelming and so you can go for an easier way, which is, to use the FIBC bag calculator, that takes in all input from you, and accordingly, pick the best for your industry needs. 

How is this calculator functional?

The FIBC bulk bag calculator will take some input from you to determine the right bulk bag that matches your safety, functionality, and usability. The procedure goes on like –

1. Dimension specification –

It is an inevitable fact that when you are selecting the best FIBC bulk bag manufacturers for your industry, it is super important to consider the finer details. The first thing that one must consider is dimension. 

Firstly select the length, width, height, SWL, and SF. FIBCs normally measure around 45-48 inches in diameter and vary in height from 39-79 inches. 

Safe working load (SWL) – It is the amount of load which a bag is designed to carry effortlessly. It can be in pounds or kilograms. 

Safety factor (SF) – It is an industry-standard that means the FIBC bulk bag must handle five or six times its SWL. The standard way to write it is in ratio, i.e., 5:1 or 6:1 SF.

2. GSM of FIBC bag:

GSM means grams per square meter area. So, if you choose higher GSM, then you get a bulkier fabric and vice versa.

3. Type of FIBC bag:

There are two types – one is coated and the other is uncoated. 

  • Breathable or uncoated fabric bags – These are non-laminated fabric bags that promote air and moisture flow, allowing both to pass through the woven material. These are ideal for products that need breathability. 

What can be stored in the uncoated FIBC bag?

–  Food and non-food grade products. 

– Coffee beans, almonds, nuts, seeds, and grains. 

– Rock, fertilizers, and gravel.


  • Coated FIBC bags – Coated/laminated with an additional polypropylene layer, these bags restraints moisture intrusion or sifting of the finer products. 

What can be stored in a coated FIBC bag?

– Dry products which are in granular, powder, crystal, and flaky form. 

– Salt, flour, and any powder. 

– Fine minerals. 

– Chemicals, glass, steel, and other similar products.

How to know whether coated will be best or uncoated?

Ask yourself the following questions while selecting between coated or uncoated –

  • What product is going to be stored in the bag?
  • What is the bulk density of the product?
  • Is it finer or a coarse material?
  • Do you need a moisture barrier or not?
  • What is the moisture percentage of the product?

In all, you need to know the characteristics of the material.

4. Dustproof:

The transportation of powdered materials is risky, as there is always a chance of leakage through the stitch needle holes. Decide whether your product transportation requires prevention from leaking.

5. Top attachment type and bottom attachment type:

Now that you’ve determined the size and type, now it is time for thinking about multiple styles for filling and emptying your FIBC bag.

6. Lifting loop specification:

Select the loop height, which is, the measurement from the top of the bag to the apex of the loop when laid flat.

7. Fabric Specification:

Select the denier, which is the weight of yarn per 9,000 meters. And, the stitch type is a hiracle or double needle. And, the pattern of stitching defines the entire structure; options that you can select are J-fold, B-fold, and Inner fold.
