When handling bulk powders, chemicals, or combustible materials, static electricity becomes a major ignition hazard. A single uncontrolled electrostatic discharge (spark) can ignite flammable powders, vapors, or combustible dust.
This is why industries operating in hazardous zones trust Type C Conductive FIBC Bags—engineered specifically to control static electricity through safe grounding.

This guide explains everything you need to know about Type C FIBC bags, including how they work, where they are used, and how to select them correctly for your industry.

✅ What Are Type C Conductive FIBC Bags?

Type C FIBC bags, also called Conductive Jumbo Bags, are bulk bags made from conductive fabrics interwoven with carbon or other conductive yarns.
Their primary purpose is:

✔ To safely dissipate electrostatic charges to the earth through grounding.

These bags are designed for operations where the presence of static electricity can lead to explosions or fire.

Type C Bags MUST be Grounded

During filling, discharge, and handling, the grounding point must always be connected to a verified earth point.
Without grounding, Type C bags cannot provide protection.

⚠️ Why Static Electricity Is Dangerous in Bulk Packaging

Static electricity is naturally generated when powders flow:

• During filling

• During emptying

• Due to friction between product and fabric

• Due to movement and vibration during transport

If this static charge is not dissipated, it may discharge as a spark.

Spark + Powder/Dust/Vapor = Explosion Risk

Industries handling combustible or flammable powders cannot use ordinary bags.
They require Type C conductive FIBCs for safe static discharge.

Key Features of Type C Conductive FIBC Bags

✔ Conductive yarns interwoven throughout the fabric
✔ Safe discharge of electrostatic energy
✔ MUST be grounded to work effectively
✔ Prevents incendive discharges in hazardous environments
✔ Suitable for products generating high electrostatic charge
✔ Designed for ATEX Zone 1 & Zone 2 (dust/vapor) operations
✔ Available from 500 kg to 2000 kg SWL

Applications of Type C FIBC Bags

Type C bags are essential in environments where flammable dusts, powders, or vapors are present.

1. Chemicals & Petrochemicals

Perfect for static-sensitive powders:

• Additives

• Polymer powders

• Plastic resins

• Detergent powders

• Hazardous chemicals

2. Food & Agro Powders

Many food powders are combustible:

• Flour, starch, sugar

• Milk powder

• Protein powders

• Spices & fine agro products

Type C ensures safe handling in explosive dust atmospheres.

3. Mining & Minerals

Used extensively for:

• Metal powders

• Explosive-grade minerals

• Pigments & oxides

• Coal dust & sulphur

4. Pharmaceuticals

For fine APIs and intermediates where explosive dust can accumulate.

5. Construction Chemicals

Safe choice for:

• Cement additives

• Fly ash

• Silica powder

Difference Between Type A, B, C & D FIBC Bags

TypeStatic Protection LevelSuitable ForType ANo static protectionNon-flammable products onlyType BPrevents high-energy propagating brush dischargesCombustible powders without flammable vaporsType CConductive bag; must be grounded; dissipates charge safelyCombustible powders + flammable vaporsType DStatic dissipative; no grounding neededHaz hazardous zones where grounding is difficult

Type C is the safest choice where grounding is assured.

Best Practices for Using Type C Conductive FIBC Bags

To maintain safety:

✔ Always ground the bag

• Use grounding cable

• Verify continuity before each use

✔ Do NOT use the bag without grounding

Even one ungrounded use can cause a spark.

✔ Train operators

Proper training prevents accidental misuse.

✔ Inspect grounding points regularly

Damaged conductive threads = risk of failure.

✔ Store in safe, dry environments

Moisture can reduce conductivity.

How to Choose the Right Type C FIBC Bag

When selecting a conductive bag, check:

• SWL (Safe Working Load): 500–2000 kg

• S.F. (Safety Factor): 5:1 or 6:1 certified

• Conductive thread continuity

• Grounding point quality

• IEC 61340 compliance

• ATEX suitability

A reliable supplier ensures consistency, traceability, and testing.

Sustainability: Are Type C Bags Recyclable?

Yes. Type C FIBCs are made from polypropylene and can be recycled after:

• Removing liners

• Cleaning product residue

• Removing non-PP components

Conclusion

Type C Conductive FIBC Bags are the safest bulk packaging solution for static-sensitive products.
By dissipating electrostatic charge through proper grounding, they prevent fires, explosions, and worker injuries.

Industries dealing with combustible powders, volatile chemicals, or explosive dust environments must use Type C FIBCs to meet ATEX, OSHA, and IEC 61340 safety requirements.

Choosing the right Type C bag ensures:

✔ Safer operations
✔ Compliance with global standards
✔ Protection of people, products & equipment
