What are the Differences Between Types A, B, C and D FIBC Fabrics?

Type A, B, C, and D bulk bags are four different types of bulk bags, and each of these bags have unique features and are designed for a wide range of applications. There are a lot of different factors that go into choosing the correct bulk bag for your application. When deciding on the proper bulk bag, you should consider the environment you will be using your bulk bag in, the materials you will be transporting, and the factors unique to the industry you work in.

  • Type A Bulk Bag – A standard bulk bag with no static protection
  • Type B Bulk Bag – A standard bulk bag with a voltage range less than 6 KV
  • Type C Bulk Bag – A standard bulk bag made with inter-connected static dissipative fabrics
  • Type D Bulk Bag – A standard bulk bag made with antistatic and static dissipative fabrics

How Do You Choose the Correct Type of Bulk Bag?

Below are characteristics of FIBC bulk bags:

MIE of Dust Non- Flammable Environment Dust Zones 21-22 Gas Zones 1-2 or Dust Zones 21-22
MIE > 1000 mJ A, B, C, D B, C, D C, D
1000 mJ ≥ MIE > 3 mJ B, C, D B, C, D C, D
MIE ≤ 3 mJ C, D C, D C, D

When Should You Choose a Type A Bulk Bag?

When to Use a Type A Bulk Bag:

  • To transport non-combustible solids, nonflammable materials, non-flammable gases, and non-flammable solvents

DO NOT USE when:

  • A flammable atmosphere is present with a Minimum Ignition Energy (MIE) ≤ 1,000mJ

When Should You Choose a Type B Bulk Bag?

When to Use a Type B Bulk Bag:

  • To transport dry, flammable products

DO NOT USE when:

  • A flammable gas or solvent is present in the atmosphere around the bag

When Should You Choose a Type C Bulk Bag?

When to Use a Type C Bulk Bag:

  • To transport combustible solids with MIE less than 3mJ and flammable vapors and gases with MIE > 0.14mJ

DO NOT USE when:

  • Ground connection is not present or damaged

When Should You Choose a Type D Bulk Bag?

When to Use a Type D Bulk Bag:

  • To transport flammable powders and combustible solids with MIE less than 3mJ

DO NOT USE when:

  • A surface is contaminated or coated with conductive material such as water or grease

How to Safely Handle and FIBC

The Flexible Intermediate Bulk Container Association (FIBCA) created a handling guidelines video to address some common situations. A full set of guidelines can be found at fibca.com, but in this video, they focused on the key points related to the filling and emptying FIBCs. Make sure to always consult with us, an FIBC supplier, regarding your specific application and handling environment.
