Types Of FIBC Bags: A, B, C & D FIBC Types Explained

Types Of FIBC Bags: A, B, C & D FIBC Types Explained
Types Of FIBC Bags

When it comes to transporting and storing bulk materials, Flexible Intermediate Bulk Containers (FIBCs), also known as bulk bags, big bags, or super sacks, are a popular choice in various industries. These bags come in different types, each tailored for specific applications based on factors such as safety, handling requirements, and the materials they will be used to transport. Let’s delve into the four main types of FIBC bags: Types A, B, C, and D.

FIBC Bags Types:

Type A FIBC Bags

Type A FIBC bags are the most basic form of bulk bags. They are constructed from woven polypropylene fabric without any additional measures to prevent the occurrence of static electricity. These bags offer no protection against the buildup of static charges and are designed for use with non-flammable products.


– Made from standard polypropylene fabric.

– No measures to prevent static electricity.

– Suitable for non-flammable materials.


  • Agriculture: Grains, seeds, fertilizers.
  • Construction: Sand, gravel, cement.
  • Food Industry: Sugar, flour, rice.
  • Pharmaceuticals: Non-hazardous powders and materials.
  • Chemical Industry: Non-flammable chemicals.

Type B FIBC Bags

Type B FIBC bags are similar to Type A but have a slightly different construction to provide limited protection against static electricity. They are made from non-conductive polypropylene fabric but lack any measures to safely dissipate static charges.


– Constructed from non-conductive polypropylene fabric.

– No measures for static dissipation.

– Offer limited protection against static electricity.


  • Chemical Industry: Non-flammable powders, granules, and materials.
  • Pharmaceuticals: Raw materials and products.
  • Mining and Minerals: Ores, minerals, and aggregates.
  • Agriculture: Animal feed, seeds, and grains.

Type C FIBC Bags (Conductive FIBCs)

Type C FIBC bags, also known as Conductive FIBCs, are designed to safely dissipate static electricity to prevent the risk of sparks. They are made from non-conductive polypropylene fabric interwoven with conductive threads or have a grid of conductive yarns that ground the bag.


– Made from non-conductive fabric with interwoven conductive threads.

– Designed to safely dissipate static electricity.

– Groundable to prevent sparks and fires.


  • Chemical Industry: Flammable powders, chemicals, and materials.
  • Petroleum and Petrochemicals: Hazardous materials and products.
  • Pharmaceuticals: Reactive substances and chemicals.
  • Manufacturing: Combustible dust (metal powders), solvents.

Type D FIBC Bags (Antistatic FIBCs)

Type D FIBC bags, also referred to as Antistatic FIBCs, are constructed from antistatic fabric that prevents the occurrence of incendiary discharges. Unlike Type C bags, Type D bags do not require grounding. They are considered a safer option for transporting and storing flammable powders and materials.


– Made from antistatic fabric.

– Prevents incendiary discharges without grounding.

– Suitable for flammable materials.


  • Chemicals: Resins, dyes, paints, and pigments.
  • Pharmaceuticals: Flammable liquids and powders.
  • Food and Beverage: Powdered milk, sugar, cocoa.
  • Agriculture: Pesticides, fertilizers, and herbicides.


Understanding the different types of FIBC bags is crucial for selecting the right packaging solution for your specific needs. Whether you are dealing with non-hazardous materials, flammable powders, or combustible dust, there is an FIBC type designed to ensure safety and efficiency in handling and transportation. Always consult with experts in bulk packaging to determine the most suitable FIBC type for your application.
