How Crohmiq® Fabric Protects Without Grounding
Crohmiq® is a patented static protective fabric used in type D FIBC bags. It works by safely dissipating static electricity into the surrounding atmosphere during filling or discharging—no ground wire required.
This reduces the risk of brush discharges, spark discharges, or propagating brush discharges, which can all cause ignition in volatile environments. It also eliminates reliance on operators remembering to ground the bag, reducing the chance of error.
Crohmiq has been independently tested and is widely accepted under IEC 61340-4-4 and NFPA 77 guidelines.
Why Ground-Free FIBCs Are the Future
In real-world operations, the most common cause of FIBC-related static ignition incidents is human error, typically failure to ground a Type C bag. Type D eliminates that variable.
At Palmetto, we believe safety should never rely on memory or luck. That’s why our anti-static bulk bags are designed to reduce risk at the source. Type D FIBCs are not just a product choice—they’re a process improvement for safety-first organizations.
Whether you're working in regulated zones or scaling into volatile new materials, Type D bags offer flexibility, speed, and safety without compromise.
Type D vs. Type C — Which Should You Choose?
| Feature | Type C FIBC | Type D FIBC |
|---|---|---|
| Requires grounding | ✅ Yes | ❌ No |
| Safe with flammable dust | ✅ Yes | ✅ Yes |
| Safe with flammable vapors | ✅ Yes (if grounded) | ✅ Yes |
| Risk of operator error | ⚠️ High (must ground correctly) | ✅ Minimal |
| Common applications | Controlled production environments | Mobile or high-throughput operations |
- Choose Type D if: You need consistent static protection in environments where grounding may be missed or isn’t practical.
- Choose Type C if: You already have strict ESD procedures in place and can guarantee grounding 100% of the time.
