Features
Type B
Made from insulating materials, Type B FIBCs prevent high-energy sparks by limiting breakdown voltage. They reduce ignition risk with flammable powders but are not suitable in environments with combustible gases or vapors.
Type C
The fabric is woven with conductive yarn, forming a fully interconnected grid with a resistance to ground of less than 1.0 x 10^7 Ohms and a breakdown voltage of under 6kV. Conductive tabs are incorporated into the FIBC, enabling safe grounding during filling and discharging. This effective grounding ensures optimal safety and reliability in applications.
Type D
Crafted from antistatic fabric with dissipative threads, Type D FIBCs safely disperse static charges at low energy levels through the corona discharge effect—eliminating the need for grounding.
Safety precautions during filling & discharging of FIBCs
| Type B | Type C | Type D | |
|---|---|---|---|
| Need for FIBC grounding & special handling equipment | No | Yes | No |
| Compliance with EC 10/2011 & FDA food contact regulation | Yes, no limitations on designs | Yes, Coated fabric, liner or net baffle designs | Yes, no limitations on designs |
| Possibility to control the FIBC with metal detection | Yes | No | Yes |
| Dissipation of static charge via Unique built in characteristics | No | No requires grounding | Yes |
The FIBC user, should ensure that isolated conductive objects (e.g. tools, bolts, clips, etc.) should not be stored on, attached to, or even temporarily placed on any type of FIBC during filling and emptying operations. The user should ensure that all conductive objects, including personnel, Type C FIBCs and any conductive contents of the FIBC, within a hazardous explosive atmosphere shall be properly earthed. Type D FIBCs are not considered to be conductive objects and are not required to be earthed. Precautions should be taken to prevent the contamination of any FIBC with substances (e.g. water, rust, oil, grease, etc.) that might create an ignition hazard or impair charge dissipation.

FIBCs and different hazard discharge types
- The FIBC construction is designed to exclude incendiary discharges from the fabric surface during their intended use.
- Type B, C & D FIBCs constructed in compliance with the requirements of IEC 61340-4-4 standard, do not necessarily ensure that hazardous electrostatic discharges, e.g. Cone Discharges or Spark Discharges from charged conductive products, will not be generated by the contents in the FIBC.
- The ability to safely use FIBCs in hazardous explosive atmospheres may change if an inner liner is installed in the FIBC. In addition to the separate requirements for FIBC and inner liners, there are requirements that certain combinations of FIBC and inner liner shall meet.

Single Trip FIBCs
Designed for one-time use and a single fill, these bags can be handled multiple times but are not intended for re-use and are tested to a 5:1 safety factor.
Multi-Trip (Standard Duty Reusable)
FIBCs that are engineered for multiple uses, these bags require careful inspection before each refill to ensure they remain undamaged, as they cannot be structurally repaired. Removable inner liners may be replaced as needed. Multi-Trip FIBCs are certified with a 6:1 safety factor for reliable performance.
Safety Factor (SF)
According to ISO 21898:2004, our FIBCs are engineered to safely handle loads from 250 kg to 3000 kg.
UV
Our FIBCs can be enhanced with UV stabilizers for added durability in outdoor conditions.
