Our Cross Corner FIBC Big Bag is precision-engineered for carbon black handling, addressing the unique challenges of fine-particle (≤200nm) containment. The diagonal cross-corner loop design (45° angle between loops) enhances lifting stability by 40% compared to standard bags, while advanced anti-sifting technology (ultrasonic sealing + heat bonding) ensures zero leakage during transportation. With a 1000kg (2200lbs) capacity, these bags are ideal for industries requiring strict contamination control, such as tire manufacturing and pigment production.
Cross-Corner Lifting System: Diagonal loops (10cm width, 600kg individual strength) create a balanced load distribution, reducing tilting by 30% during crane lifting and improving maneuverability in tight spaces.
Ultra-Tight Containment: Triple-layered fabric (220 GSM) with ultrasonic-sealed seams (100% airtight) and filler cord reinforcement (polyester) prevents carbon black sifting—tested to retain 99.99% of particles during vibration testing (10Hz, 24 hours).
Static Dissipation: Optional antistatic treatment (surface resistivity <10^9 Ω) minimizes electrostatic buildup, compliant with IEC 61340-4-4 for explosive environments (ATEX Zone 21/22).
Durable Construction: UV-resistant PP woven fabric with 20% higher tensile strength (250 N/5cm) than standard FIBCs, ensuring resistance to abrasion from carbon black particles.
Certifications: Compliant with ISO 21898:2024 and FDA 21 CFR §177.1520 (for indirect food contact carbon black), with optional REACH and RoHS testing.
Rubber Industry: Transport carbon black (N330, N550 grades) used in tire treads, conveyor belts, and O-rings for enhanced wear resistance.
Paints & Coatings: Securely handle pigment-grade carbon black (≥99% purity) for automotive paints, inkjet inks, and plastic colorants.
Plastics: Contain masterbatches (20-50% carbon black concentration) and reinforcing fillers in polypropylene and polyethylene production.
Q: How effective is the anti-sifting design?
A: Bags pass ASTM D5638 sieve tests with <0.1% material loss after 100 hours of vibration, exceeding industry standards for fine-particle containment.
Q: Can these bags be cleaned for reuse?
A: Yes, they can be vacuum-cleaned (HEPA filter) and inspected via pressure testing (5kPa) to ensure no micro-tears before reuse—typically 3-5 cycles for non-critical applications.
Q: What is the lead time for custom orders?
A: Typically 4-6 weeks for orders with custom features like antistatic treatment or printing; rush orders (2-3 weeks) available with premium pricing.
Q: Are they suitable for food-grade applications?
A: No, these bags are designed for industrial use. For food-grade needs, see our U-panel Food Grade Bulk Bags (FDA-compliant).
