A to D of FIBC Bags: The Differences Between the Types of FIBC Jumbo Bags


 FIBC or Flexible Intermediate Bulk Containers made from woven polypropylene is a widely accepted and preferred mode for storage and transportation of solid dry bulk materials. Also known as ‘Jumbo bags’ or ‘Bulk Bags,’ they come in a variety of different materials, dimensions, and storage capacities, while they are highly customizable for the specific needs and unique requirements of customers.

When it comes to the types of FIBC Jumbo Bags, they are broadly categorized into four types, each with its own set of features and uses. Here’s brief information on the types and usage of FIBC Bulk Bags.

Type A Bags

Type A FIBC Bulk Bags are manufactured from plain-woven polypropylene or any other fabric of non-conductive nature. Since they offer no protection from static electricity, they must not be used for the purpose of storing or transporting any flammable material. They are recommended to be used for transporting non-flammable goods, though care must be taken to ensure that these bags do not come in contact with flammable solvents or gases.

Uses:

·         Transporting and storing non-flammable products.

·      Strictly not to be used in a flammable environment with an ignition energy of at least ≤1,000mJ.

Type B Bags

Like Type A FIBC Bulk Bags, these bulk bags are also crafted out of plain-woven polypropylene or other non-conductive fabrics and cannot dissipate static electricity.

But the main difference between Type A & B FIBC Jumbo Bags is that Type B FIBCs have a low breakdown voltage, not exceeding 6 kV. This allows these bags to be safe and effective in environments where propagating brush discharges can take place. However, because these bags fail to dissipate static electricity, they are not considered ‘antistatic’.

Uses:

·         Transportation of dry and flammable powders

·         Should not come in contact with flammable gases or solvents.

·         Recommended for use in environments with ignition energies <3mJ.

Type C Bags

Also referred to as conductive FIBCs or groundable FIBCs, Type C FIBC Bulk Bags are built from non-conductive polypropylene material interwoven with conducting threads in a grid-like pattern. The key thing to remember while filling and discharging these bags is that the user must ensure there is an electrical connection between the conducting threads, while the bag is duly connected to a grounding point. This grounding/earthing is critical to the safe handling and operation of these bags.

Uses:

·         Flammable powder substances

·        Can be safely used in environments where explosive gases, dust, or solvents are present.

·         Not to be used without a secure and undisrupted and ground connection.

Type D Bags

Also known as Dissipative FIBC Bulk Bags, Type D Bags are made from a blend of antistatic fabrics and those with static dissipative properties. This combination of qualities allows these bags to be used safely in an atmosphere with brush discharges without needing a ground connecting point.

Uses:

·         Safe transportation of flammable and combustible powders.

·     Recommended for use in environments where flammable gases, dust, or solvents are present.

·    Not to be used in case of surface contamination with water, grease, or conductive materials.
