Chapter 03 // Electrostatic Classification & Safety

IEC 61340-4-4 Certified Charge Dissipation for Explosive Environments.

When rapid pneumatic filling occurs, dry powders generate catastrophic brush discharges. We engineer four electrostatic classes according to ambient explosive atmosphere zoning.

FIBC Classification Construction & Mechanism Breakdown Voltage Safe Operating Zone
Type A Standard plain woven polypropylene fabric. No electrostatic dissipation mechanism. > 6.0 kV Non-combustible solids & non-flammable atmospheres only (MIE > 1000 mJ).
Type B Standard fabric with insulating breakdown voltage controlled to prevent propagating brush discharges. < 6.0 kV Dry combustible dust atmospheres without flammable solvents (MIE > 3 mJ).
Type C (Conductive) Interwoven grid of carbon or silver conductive filaments grounded during filling and discharging. Resistance < 1.0 × 10⁷ Ω Explosive atmospheres with flammable gases, vapors, and combustible dusts (Zones 1 & 2). Grounding required.
Type D (Dissipative) Quasi-conductive anti-static fibers that dissipate static charge into the atmosphere via safe low-energy corona discharge. Inherent corona release Explosive solvent vapor atmospheres without grounding requirement. Safe in presence of combustible dusts.
Chapter 04 // The Quality Floor & Destructive Testing

The Anatomy of Certified Containment: Tested to Rigorous Safety Proof Limits.

Every batch undergoes destructive cyclic top-lift testing, drop impact trials, and spectrophotometric UV analysis. Bulk packaging failure is not an option when transporting hazardous or food-grade compounds across ocean corridors.

Multi-ton Palletized FIBC Bags Quality Proof Lineup
12.0 MT Proof Rig Test Load (6:1 SF)

0.00% Seam Particulate Sift

1. 100% Virgin High-Tenacity Polypropylene

Formulated with virgin homopolymer PP resin and hindered amine light stabilizers (HALS). Retains >70% tensile strength after 1,200 hours of continuous UV exposure, preventing brittleness during dockside outdoor staging.

2. Triple-Needle Sift-Proof Seam Engineering

Equipped with non-woven polypropylene felt cord or soft twisted yarn filler sewn into the chain stitch. Under hydrostatic powder pressure, the cord expands to seal all needle apertures, preventing micron-scale powder loss.

3. Stevedore & Cross-Corner Lifting Straps

Woven from high-tenacity multifilament polyester and polypropylene yarns with break loads exceeding 5,000 kg per loop. Sewn down 300mm into the body fabric with safety lockstitches to withstand aggressive forklift handling.

4. Co-Extruded Multi-Barrier Liners

Supplied with integrated form-fit LDPE, aluminum barrier foils, or EVOH gas barriers. Completely locks out ambient humidity and oxygen ingress for reactive chemicals, active pharma ingredients, and specialty food additives.
