Type C and Type D Antistatic FIBCs: Choose According to Your Needs
When transporting combustible powder, chemical raw materials and flammable dust, anti-static bulk bags are essential for industrial safety production. Static sparks are easily generated during loading, unloading and handling, posing potential fire hazards.
May 20,2026
When transporting flammable powder materials, chemical raw materials and combustible dust, electrostatic protection is an essential safety standard in production operations. Static electricity easily accumulates in bulk bags during filling and discharging, and static sparks generated in high-risk environments may lead to fire accidents. With professional safety protection design, antistatic bulk bags can protect on-site staff and help enterprises meet production safety regulations. There are two mainstream types, Type C and Type D, which adopt different static dissipation principles. Proper selection based on working conditions can eliminate fire hazards from the source and ensure fully compliant and safe operations.
Importance of Antistatic Protection in Bulk Bag Transportation
Static electricity keeps accumulating in bulk bags during material filling, transportation and discharging processes, which may cause electrostatic discharge, open sparks and surface brush discharge. Once contacting combustible dust, volatile steam and flammable gas, potential safety accidents will occur. Such high-risk working scenarios are subject to international safety standards including NFPA, OSHA, IEC and ATEX. Complete static electricity prevention measures can fully protect staff, production equipment and entire production lines.
What is Type C Antistatic FIBC Type C
antistatic bulk bags are embedded with complete conductive yarn mesh structure, which can steadily conduct static electricity generated by the bags to the ground for release.
Working Principle
Static electricity is led out through special grounding cables, and the bulk bags must be reliably grounded during filling and discharging operations.
Advantages
It features high-level antistatic performance after correct grounding, suitable for most high-dust and high-risk working environments.
Limitations
It will lose antistatic effect completely without standard grounding, bringing huge safety risks. In addition, operators need professional skills and regular daily safety inspections are required.
Application Scenarios
Transportation of various flammable powders, combustible dust areas with stable grounding conditions, and production factories equipped with complete static protection management systems.
What is Type D Antistatic FIBC
Made of special static dissipative fabric, Type D antistatic bulk bags can realize independent static control without external grounding devices.
Working Principle
Specially-made antistatic materials and surface protective coatings effectively restrain surface brush discharge, and can prevent flammable sparks without grounding cables.
Advantages
No grounding operation is needed, which greatly reduces human operation errors and fits efficient, fast-paced and mobile working modes.
Limitations
It is not applicable to working environments with high-concentration solvents, and the bags must be kept clean and dry during storage and usage.
Application Scenarios
Work sites inconvenient for grounding, high-flow rapid filling production lines, widely used in food processing, fine chemical industry, mineral raw material processing and other industries.
Comparison Items | Type C Antistatic FIBC | Type D Antistatic FIBC |
Static Protection Mode | Conductive transmission type, standard grounding required | Self static dissipation type, no grounding needed |
Applicable Working Environment | Standardized factories with fixed sites and standardized management | Flexible working sites with variable locations |
Operation Requirements | Grounding cable connection required with complex procedures | Simple operation with low labor cost |
Common Applicable Materials | Flammable chemical raw materials, mineral powder, powdery wax and more | Flammable chemical raw materials, mineral powder, powdery wax and more |
Potential Risks | Extremely high risks if used without grounding | Protection performance affected by dirt and dampness, incompatible with high-concentration solvents |
Scientific Selection Guidelines for Antistatic FIBCs
Enterprises shall select suitable antistatic bulk bags by comprehensively considering material characteristics, production processes and factory hardware conditions:
- Confirm hazard classification of transported materials, focusing on flammability and dust explosion risks
- Comply with NFPA and ATEX safety standards to meet explosion-proof grade requirements of filling and discharging areas
- Confirm whether stable and reliable grounding facilities are available on site
- Evaluate professional skills of frontline operators and on-site standardized operation procedures
- Select products according to material flow rate, bulk density and actual discharging methods 6. Choose bulk bags in line with internal production safety, environmental protection and occupational health management norms
Common Usage Mistakes to Avoid
Hidden dangers in daily use are mainly caused by insufficient staff training, non-standard operation procedures and improper product selection, which will weaken antistatic effects. Please avoid the following mistakes:
- Never use Type C antistatic bulk bags without completing grounding work
- Do not take it for granted that Type D bulk bags fit all working scenes with high-concentration solvents
- Reuse antistatic bulk bags without safety inspection and damage check is forbidden
- Attach importance to pre-job safety training to ensure operators fully understand static hazards and standard operation specifications
- Abandon the wrong purchasing concept of only focusing on price while ignoring safety protection grade
