FIBCs / Bulk Bags

FIBC Types

FIBCs are classified into four primary types based on the level of static protection they provide. Choosing the right type depends on the material being handled, the surrounding environment, and whether combustible dusts, flammable gases, or vapors may be present during filling, storage, or discharge.

Along with Type A, Type B, Type C, and Type D FIBCs, Action Packaging also offers baffle bulk bags, which are designed to improve bag shape, stacking stability, and transportation efficiency.

Type A FIBC

Type A bulk bags are made from standard woven polypropylene and do not provide static protection. They are commonly used for non-hazardous dry bulk materials in environments where flammable gases, vapors, or combustible dusts are not present.

Type A FIBCs are often used for:

• Sand and aggregates
• Agricultural products
• Minerals and powders
• Plastic resins
• Non-hazardous industrial materials

Because Type A bags do not dissipate static charge, they should not be used in applications where ignition risks are present.

Type B FIBC

Type B bulk bags are similar to Type A bags because they do not actively dissipate static electricity. However, Type B bags are made with materials that have a low breakdown voltage, helping reduce the risk of highly energetic propagating brush discharges.

Type B FIBCs may be used for certain dry, combustible powders, but they are not considered antistatic and should not be used in environments with flammable gases or vapors.

Typical applications include:

• Fine powders
• Chemical ingredients
• Industrial minerals
• Certain combustible dust products

Type C FIBC

Type C bulk bags, also called conductive or groundable FIBCs, are designed with conductive yarns woven into the bag structure. During use, the bag must be properly grounded to safely dissipate static electricity generated during filling and discharge.

Type C bags are often used for materials and environments involving:

• Flammable powders
• Combustible dusts
• Hazardous chemical products
• Sensitive industrial materials

Proper grounding is critical for Type C FIBCs to perform safely and effectively.

Type D FIBC

Type D bulk bags are made with static-dissipative fabrics designed to reduce dangerous electrostatic charge without requiring a connection to ground. This can help reduce the risk of sparks, brush discharges, and propagating brush discharges during normal handling.

Type D FIBCs are commonly used for:

• Flammable powders
• Combustible dusts
• Chemical products
• Sensitive manufacturing materials

Because Type D bags do not require grounding, they can help simplify handling procedures while still supporting static-control performance.

Baffle Bulk Bags

Baffle bulk bags are designed with internal fabric panels sewn into the corners of the bag. These baffles help the bag maintain a square shape when filled, reducing bulging and improving storage and transportation efficiency.

Compared to standard bulk bags, baffle bags can help improve:

• Pallet utilization
• Stacking stability
• Warehouse organization
• Trailer and container loading efficiency
• Overall package presentation during transport

Baffle FIBCs are commonly used for food ingredients, resins, chemicals, agricultural products, and other dry bulk materials where space efficiency matters. Learn more about our baffle bulk bags.

Custom FIBC Solutions

Every bulk material has its own handling requirements. Action Packaging can help you evaluate the right FIBC construction based on your product, capacity, filling method, discharge process, storage conditions, transportation needs, and safety requirements.
