Product Description
Chemical manufacturers face a unique packaging challenge: many dry chemical compounds generate electrostatic charges during filling and discharge — yet handling facilities may not have the infrastructure for grounded Type C FIBC bags on every line. The Type B FIBC Bags for Chemical Powders solves this precisely.
Built from low breakdown voltage polypropylene fabric certified to IEC 61340-4-4, these bags prevent Propagating Brush Discharges (PBD) without requiring any grounding connections. For chemical plants handling resins, pigments, fillers, and mineral additives in dust-controlled facilities free from flammable vapours, Type B delivers the right level of static protection at the right cost.
Why Choose This Bag?
- Prevents PBD without grounding — ideal for chemical facilities where grounding infrastructure is limited
- Chemical-resistant PP fabric maintains integrity with a wide range of dry compounds
- Optional PE or foil liners protect moisture-sensitive chemical powders during transit
- Full IEC 61340-4-4 electrostatic test documentation for ATEX/DSEAR compliance records
- Custom printing for chemical identification, hazard labelling, and branding
| ⚠️ SAFETY NOTE: Type B FIBC bags must NOT be used in facilities where flammable solvents, vapours, or gases are present. If your chemical handling environment has vapour risk zones, upgrade to Type C (grounded) FIBC bags. |
Typical Applications Industries
- Synthetic resins and polymer powders (PVC, ABS, epoxy)
- Inorganic pigments and colour concentrates
- Mineral additives: calcium carbonate, titanium dioxide, barium sulphate
- Powder coating compounds and thermosetting resins
- Silica, zeolite, and aluminium oxide powders

Frequently Asked Questions
Q1: Are Type B bags suitable for powder coating compounds?
Yes. Powder coating compounds are typically dry thermosetting resins with MIE values well above 3 mJ in environments where no flammable vapours are present during bag filling and discharge. Type B FIBC bags meet the electrostatic safety requirements for this application. Always verify your specific compound’s MIE with your safety engineer.
Q2: Should I use a liner with Type B bags for chemical powders?
For fine or hygroscopic chemical powders, we strongly recommend a PE liner or foil liner to prevent moisture ingress and contamination. The liner does not affect the bag’s Type B electrostatic classification, as the liner is fitted inside the outer fabric.
Q3: Can Type B bags be used for hazardous chemicals requiring UN certification?
No. UN-certified bags (for hazardous goods under the UN Orange Book) require a completely separate certification and construction process. Type B classification relates only to electrostatic properties. For UN hazardous goods, please contact us for our UN-certified FIBC range.
Q4: What documentation do chemical facilities typically need for Type B FIBC procurement?
Chemical procurement teams typically require: IEC 61340-4-4 electrostatic test report, ISO 21898 structural conformity, COA (Certificate of Analysis) for fabric material, and batch traceability. We provide all of these as standard. REACH and RoHS material declarations are available on request.
