Product Overview
Our Type B Anti-Static Bag is engineered to mitigate static electricity risks in bulk packaging, making it a critical solution for industries handling flammable or explosive materials. Unlike standard container bags, this product integrates anti-static masterbatch into the fabric during weaving and coating— a proprietary process that ensures uniform static dissipation across the entire bag surface. With a maximum breakdown voltage of less than 6KV (per international safety standards), it prevents the buildup of high-intensity static charges that could ignite flammable dust (e.g., flour, plastic dust, or coal dust). Crafted from high-strength woven polypropylene (PP) reinforced with anti-static fibers, it balances static control with load-bearing reliability, supporting safe loading, unloading, and transportation of bulk materials in low-risk hazardous areas.
Scenario-Based Solutions
Chemical Powder Manufacturing & Distribution
Chemical plants producing talcum powder, sulfur powder, or fertilizer often face static-related fire risks. Our Type B Anti-Static Bag eliminates this threat by dissipating static charges as they form, preventing sparks that could ignite airborne dust. It’s also resistant to chemical absorption, ensuring the bag doesn’t degrade when in contact with mild corrosive powders, making it ideal for long-haul shipping to regional distributors.
Food Processing (Flour & Spice Bulk Handling)
Flour mills and spice manufacturers deal with fine, flammable dust that poses explosion risks in enclosed spaces. Our anti-static bag complies with food-grade standards (FDA and EU 10/2011), so it’s safe for direct contact with edible powders. The static control feature ensures no dust clings to the bag interior during emptying, reducing product waste and maintaining hygiene—critical for food safety audits.
Plastic & Polymer Pellet Storage
Plastic resin pellets (e.g., polyethylene, polypropylene) generate static when rubbed against bag fabric during handling. This static can attract dust, contaminating the pellets and compromising final product quality (e.g., for injection molding). Our Type B bag dissipates static, keeping pellets clean and ensuring consistent performance in downstream manufacturing processes.
Key Product Features
• Uniform Anti-Static Protection: Anti-static masterbatch is blended into the fabric matrix (not just coated), ensuring long-lasting static control even after repeated use or abrasion.
• Low Breakdown Voltage: <6KV surface breakdown voltage (tested per IEC 61340 standards), preventing dangerous static arcs in flammable dust environments.
• High Tensile Strength: Woven PP fabric with 1800N/5cm warp and weft strength, supporting safe working loads (SWL) of 500-1500kg.
• Dust-Proof Design: Heat-sealed seams and a reinforced top closure (spout or duffle) prevent dust leakage, protecting both workers and the environment.

Customization Services
To meet unique industry needs, we offer tailored Type B Anti-Static Bag solutions:
• Anti-Static Performance: Adjust anti-static masterbatch concentration (2-5%) for varying static risk levels (e.g., 5% for high-dust environments like coal processing).
• Size & Load Capacity: Customize width, height, and SWL (up to 2000kg with reinforced fabric) to fit your filling equipment and transportation vehicles.
• Closure & Discharge: Choose between spout, duffle, or flap closures; add bottom discharge valves (manual or automated) for easy emptying in cleanrooms.
• Branding & Labeling: Print safety warnings (e.g., “Anti-Static – Do Not Ground”), batch numbers, or company logos using static-neutral inks to avoid compromising anti-static properties.
• Material Upgrades: Opt for UV-stabilized fabric for outdoor storage or chemical-resistant liners for aggressive powders (e.g., sodium bicarbonate).
