Anti-Static FIBC Bag Flat Bottom Polypropylene Jumbo Bag

Understanding Static Hazards in Bulk Bag Operations

When filling or emptying FIBCs, several actions generate static electricity:

• Material flowing through filling spouts

• Product particles rubbing against bag fabric

• Bag movement during handling

• Rapid discharge of fine powders

Without proper static control, accumulated charges can discharge as sparks—potentially igniting flammable dust clouds or vapors. Anti-static FIBCs provide controlled paths for static dissipation, eliminating this danger.

Types of Anti-Static FIBCs: Choosing the Right Protection

Type B Anti-Static Bags

• Made from fabric with breakdown voltage below 6kV

• Prevents dangerous propagating brush discharges

• Does NOT require grounding during use

• Suitable for combustible dusts in non-flammable atmosphere environments

• Important: Not for use in flammable gas or solvent environments

Type C Anti-Static Bags (Groundable)

• Woven with interconnecting conductive threads (typically carbon or stainless steel)

• All conductive elements connect to grounding tabs or loops

• MUST be grounded during filling and emptying

• Provides full path to earth for static dissipation

• Suitable for Class 1 and Class 2 hazardous environments

• Ideal for flammable powders, explosive dusts, and solvent-containing materials

Type D Anti-Static Bags (Static Dissipative)

• Special fabric construction dissipates static energy through corona discharge

• Does NOT require grounding (though grounding recommended for maximum safety)

• Prevents all types of electrostatic discharges

• Suitable for sensitive environments where reliable grounding cannot be guaranteed

• Ideal for operations with multiple bag changeovers or mobile equipment

Industry Standards Reference

Type C Requirements

• Surface resistance typically >10⁸ ohms

• Dissipates energy through corona discharge

• May still recommend grounding for dual protection

Testing Verification

Each production batch is tested for:

• Conductive path continuity (Type C)

• Breakdown voltage (Type B)

• Discharge energy verification (Type D)

• Surface resistivity measurements

Important Selection Considerations

Know Your Material’s Properties

• Is your material combustible or flammable?

• Does it generate significant static during handling?

• What is the minimum ignition energy (MIE)?

• Are flammable solvents or gases present?

Understand Your Environment

• Is the area classified as hazardous?

• Are grounding points readily available?

• Will bags be moved between grounded and ungrounded equipment?

• What are the atmospheric conditions?

Choose the Correct Type

• Type B: Low-risk dry products, non-flammable atmosphere

• Type C: Flammable products with grounding capability available

• Type D: When grounding unreliable or maximum safety required

Never Assume “One Size Fits All”

Using the wrong anti-static protection can be as dangerous as using no protection. Type B bags in solvent environments provide false security. Ungrounded Type C bags accumulate more charge than standard bags. Always verify your selection with qualified safety professionals.
