Type C conductive bag (also known as groundable conductive FIBC) is a specialized packaging product designed for flammable and explosive environments, primarily used to eliminate safety hazards caused by static electricity accumulation during material loading, unloading, and transportation. Its key design feature is that conductive filaments are interwoven into both the bag fabric and lifting slings, combined with the use of conductive films. Through grounding the conductive filaments, an electrostatic discharge channel is formed, which can effectively dissipate static electricity generated during loading and unloading, fundamentally preventing sparks from electrostatic discharge and avoiding dangerous incidents such as combustion and explosions.
The surface resistance is strictly controlled below 10⁷Ω, complying with international electrostatic safety standards. Made of high-strength polypropylene, these bags feature excellent tear resistance and chemical corrosion resistance.
Q1. What is a Type C conductive bag and how does it differ from others?
A Type C conductive bag is woven with interconnected conductive threads throughout the fabric and lifting slings, allowing static electricity to be safely discharged to the ground. Unlike Type A or B, Type C bags actively dissipate static charge, making them safe for flammable vapors and combustible dusts.
Q2. What is the surface resistance requirement for these bags?
The surface resistance is strictly controlled to be below 10⁷Ω. This ensures compliance with international electrostatic safety standards and guarantees effective dissipation of static charge during operation.
Q3. Is grounding mandatory when using Type C conductive bags?
Yes, grounding is absolutely essential. The bag must be connected to a proper earth ground before filling or discharging. Without grounding, the conductive filaments cannot dissipate static electricity, maintaining a risk of ignition.
Q4. Can Type C conductive bags be customized?
Yes, we support full customization of size, capacity, and style. Parameters like inlet/outlet configurations, leak-proof stitching, and PE inner bags can be adjusted based on specific material characteristics and usage scenarios.
Q5. What materials are used in construction?
The bag body is made from high-strength polypropylene (PP) interwoven with specialized conductive filaments. This combination provides excellent tear resistance and chemical corrosion resistance for demanding industrial environments.
Q6. Which industries benefit most from Type C bags?
Key sectors include the chemical, pharmaceutical, and new energy industries (lithium battery materials). They are also essential for food and feed additives or any environment where static electricity poses a significant explosion risk.
