Start with the process
Moving product can create electrostatic charge. The material, equipment, and surrounding atmosphere all matter when selecting a bag.
Engineered static protectionCROHMIQ®
CROHMIQ®
Type D FIBC
Static dissipation.
Built into the fabric.
CROHMIQ Type D bulk bags dissipate electrostatic charge without requiring a bag-to-ground connection. Let’s match the bag design and documentation to your product and process.

How CROHMIQ worksCharge control.
Charge control.
Without a bag grounding lead.
Filling and emptying can generate static charge. CROHMIQ fabric uses a different dissipation mechanism from a grounded Type C bag.
Special yarns, woven in
CROHMIQ incorporates quasi-conductive yarns within polypropylene fabric to help control accumulated charge.
Low-energy corona discharge
The fabric releases charge into the surrounding atmosphere through low-energy corona discharge, without a bag-to-ground connection.

Type C and CROHMIQ Type D: different approaches
| Consideration | Type C | CROHMIQ Type D |
|---|---|---|
| Charge dissipation | Conduction through a connection to earth | Low-energy corona discharge through the fabric |
| Bag grounding | Required during filling and emptying | No bag-to-ground connection required |
| Selection | Review the complete application, compatible liners, tested limits, and operating instructions. | |

Send your current specification or describe the operation. We’ll help bring the requirements into one discussion.
What are you filling?
Product characteristics, filling and emptying methods, potential atmospheres, and your site’s hazard assessment.
How must the bag work?
Dimensions, safe working load, lifting loops, openings, discharge arrangements, and printing.
Review the complete bag
Liners, attachments, and other components must be compatible with the specified static-protective design.
Define what you need
Design-specific test documentation, labelling, food-contact requirements, quantities, and delivery plans.

Common questionsClear answers.
Clear answers.
A useful starting point.
Does the bag need to be grounded?
CROHMIQ Type D fabric dissipates charge without a bag-to-ground connection. This does not remove grounding requirements for other conductive equipment, objects, or personnel. Follow the bag instructions and your site’s operating procedures.
What if our site requires grounding the bag?
Texene’s Technical Note 133 explains that a CROHMIQ bag may be grounded when required by site procedures. Grounding it does not change its classification to Type C. Review the intended arrangement with us.
Can I use a liner?
The liner must be compatible with the complete static-protective bag design. Send the liner material, construction, and intended use so the bag-and-liner combination can be reviewed.
Can we specify food-contact bags?
Yes, we can review food-contact requirements. Suitability depends on the complete bag, including coatings, sewing materials, liners, and the intended contact conditions. Request documentation for your specific construction.
Can these bags be reused?
Do not assume a bag is suitable for reuse. Texene discusses reuse within a properly designed refurbishment and safety-testing program. Review the specific design and operating conditions before considering reuse.
Can you audit our existing specification?
Yes. Send your specification, product information, process details, and required documentation. We can identify points needing clarification and discuss design options.
