Lamifab Industries

FIBC bags (Flexible Intermediate Bulk Containers), or "jumbo bags," are large, durable, woven polypropylene containers designed for transporting and storing dry, flowable materials. They are defined by their high load capacity (up to 3,000+ lbs), versatility across industries (construction, agriculture, food, chemicals), and cost-effective, stackable design.Key Descriptions and Specifications

• Material: Primarily made from woven polypropylene fabric (PP), which can be coated (laminated) for moisture resistance or uncoated (breathable).
• Types (by Static Safety):
  • Type A: Standard non-conductive, for non-flammable materials.
  • Type B: Low-breakdown voltage, safe for dry, non-flammable powders.
  • Type C: Conductive bags that require grounding (static-protective).
  • Type D: Anti-static/dissipative fabric that does not require grounding.
• Key Features & Components:
  • Liners: Internal, removable liners (e.g., PE) protect sensitive products from moisture and contamination.
  • Lifting Loops: Standard options include 4-loop or single-loop, allowing for easy crane or forklift handling.
  • Filling/Discharging: Designed with customizable filling spouts and discharge spouts for efficient handling.
• Specialty Types:
  • UN Certified: For hazardous, regulated materials.
  • Ventilated/Breathable: For agricultural products like potatoes, onions, or firewood.
• Common Uses: Construction (sand, gravel), Food (grain, sugar, flour), Agriculture (seeds, fertilizer), and Waste management. 

Conductive Type C FIBC bags are groundable, conductive polypropylene bags engineered to dissipate electrostatic charges, preventing explosions in flammable or combustible environments. They feature interwoven conductive threads or tapes (<107 Ohm resistance) that require a secure, grounded connection during filling and discharge. Key Characteristics and Technical Specifications

• Grounding Required: Must be connected to a ground point (<1.0  10⁷ Ohm) at all times during use.
• Conductive Material: Made from woven fabric containing conductive threads, often in a grid pattern (up to 50mm spacing) or stripe pattern (<20mm spacing).
• Performance Metrics: Designed for handling hazardous products in zones with high-risk dust, gases, or vapor.
• Safety Features: Often used with conductive liners (Type L1/L2). 

Common Applications and Industries

• Flammable Chemical Transportation: Used for handling powders and granules that can produce ignitable dust.
• Pharmaceutical and Food Industry: Suitable for bulk handling in potentially explosive atmospheres (e.g., powders with low minimum ignition energy).
• Mining & Construction: Ideal for combustible materials. 
• Mandatory Grounding: Never use a Type C bag without a proper ground connection; grounding failure makes them dangerous.
• Inspection: Regularly inspect grounding points to prevent hazards. 

Key Differences from Other Types

• Vs. Type B: Type B does not require grounding but has limited breakdown voltage.
• Vs. Type D: Type D bags are static-dissipative without the need for grounding connections. 

Note: Type C bags are governed by strict safety standards, such as IEC 61340-4-4, designed to prevent electrostatic ignition
