Conductive Type C Anti-Static FIBC Bulk Bags

Type C conductive FIBC bulk bags are specialized industrial packaging solutions designed for environments where flammable gases, vapors, or combustible dusts create an explosion risk.

Constructed from non-conductive polypropylene fabric interwoven with a grid of continuous conductive fibers, these bags prevent incendiary electrostatic discharges during rapid filling and discharging processes. To ensure operational safety, Type C bags must be electrically grounded (connected to an earth ground) during both filling and emptying cycles to safely dissipate accumulated static electricity.

Technical Features

• Interwoven conductive carbon or silver filaments (Grid or stripe pattern)
• Fully interconnected lifting loops and seams for continuous electrical pathways
• Designated grounding tabs for earth-bonding clamps
• Compatible with PE or Aluminum Foil inner liners (Multi-layer protection)

Why Choose Type C Conductive Bags?

1. Static Dissipation: Safely channels electrostatic charges away from the material to the ground, eliminating the risk of brush discharges or sparks.
2. Explosion-Risk Compliance: Engineered for industries operating in ATEX-classified zones or handling powders with low Minimum Ignition Energy (MIE).
3. Structural Safety: Combines heavy-duty 1,000kg+ load-bearing capacity with strict electrical conductivity standards.

Industrial Applications

1. Renewable Energy & Battery Materials: Transporting highly reactive materials like lithium powders and graphite carbon, where static discharge during high-speed gravity feeding can be hazardous.
2. Fine Chemicals & Engineering Plastics: Packaging for specialized resin granules, volatile additives, and flame retardants prone to static buildup.
3. Pharmaceutical & Food Additives: Handling fine organic powders that exhibit low minimum ignition energies when suspended in air.

Operational Guide: Strict Grounding Requirements

To ensure the anti-static properties of a Type C bag function as designed, logistics teams must observe the following technical protocols:

1. Verify Connection Points: Before material begins flowing, attach the facility's grounding clamp directly to the designated conductive tab on the bag.
2. Resistance Monitoring: Ensure the grounding system verifies a resistance-to-earth reading of less than $10^7$ Ohms.
3. Isolate Non-Conductive Barriers: If using an internal plastic liner, ensure it is a specialized conductive or antistatic liner that does not insulate the material from the outer bag's conductive grid.

Frequently Asked Questions

1. What happens if a Type C conductive bag is not grounded?

If a Type C bag is not connected to an earth ground during operation, it behaves like an ungrounded conductor. It will store static electricity instead of dissipating it, which significantly increases the risk of a high-energy electrostatic spark that can ignite surrounding dust or flammable vapors.

2. What is the difference between Type C and Type D FIBCs?

Type C bags require physical grounding via a wire/clamp system to dissipate charge. Type D bags are made from static-dissipative fabrics that dissipate charge into the atmosphere via corona discharge without requiring a ground connection. Type C is preferred in many heavy chemical sectors where positive confirmation of grounding is mandated by safety protocols.

3. Can conductive bags be used with aluminum foil liners?

Yes, but they must be structurally matched. When shipping highly sensitive chemical or battery powders, a specialized aluminum composite liner can be integrated into the Type C bag to provide simultaneous moisture-barrier insulation and static mitigation.

Request an Anti-Static Layout Review

If you are handling materials with specific electrostatic risks but do not have full engineering specs, share your baseline operational parameters for a technical assessment:

• What material will you be loading? (e.g., Lithium powder, carbon black, flammable chemicals)
• Is your facility classified under specific ATEX/explosion-risk zones? (Yes / No / Unknown)
• What is your target payload weight per bag? (e.g., 1,000kg)
• Do you require additional moisture protection? (e.g., PE or Aluminum Foil inner liner)

Our technical team will review your application parameters and recommend appropriate fabric densities and structural layouts.
