Product Features


Sift Proofing Construction


Engineered with ultra-tight woven PP fabric (basis weight 200–220 g/m²) and heat-sealed seams, this bag prevents fine particles from sifting through. The fabric features a 0.1 mm pore size to contain powders and granular materials with particle sizes over 50 microns. All seams undergo a double-stitching and heat-sealed process to eliminate gaps, ensuring 99.9% sift resistance—tested in accordance with ASTM D4726 standards for leakage prevention.


TYPE C Conductive Properties

Incorporates interwoven conductive fibers (10% carbon content) evenly distributed throughout the PP fabric, enabling static charge dissipation. TYPE C classification requires the bag to be grounded during use, with a surface resistance of 10⁴ to 10⁶ ohms when properly connected to an earth ground. This design reduces the risk of electrostatic discharge (ESD), which is critical for handling materials prone to ignition, such as fine chemicals or powdered metals.


One Ton Load Capacity

Designed with a Safe Working Load (SWL) of 1000 kg and a safety factor of 5:1, ensuring it can withstand a maximum breaking load of 5000 kg. The bag features 4 conductive lifting loops (integrated with the main fabric’s conductive fibers) positioned symmetrically to distribute weight evenly, compatible with standard forklifts and cranes equipped with grounding clips.


PP Material Advantages

The base material is food-grade polypropylene (PP) with high chemical resistance, suitable for contact with non-aggressive powders and granules. The fabric exhibits tensile strength of 14 kN/m (warp) and 12 kN/m (weft), resisting tearing during filling and transportation. Optional UV stabilization (with 0.3% UV inhibitors) extends service life to 6–9 months in outdoor storage, though indoor use is recommended for conductive components’ longevity.


Applications


This FIBC bag is ideal for industries requiring electrostatic safety and material containment:


Chemical Processing: Transports fine chemical powders (e.g., pigments, catalysts) where sifting could cause cross-contamination or ESD risks.

Pharmaceutical Manufacturing: Contains active pharmaceutical ingredients (APIs) with strict containment requirements, preventing product loss and ensuring workplace safety.

Metal Powder Handling: Safely carries aluminum, zinc, or iron powders—combustible materials where static discharge could ignite dust clouds.

Mineral Processing: Stores and transports fine mineral powders (e.g., talc, limestone) with minimal leakage, maintaining clean production environments.


FAQ


What makes this bag "sift proofing"?

Its sift resistance comes from ultra-tight woven PP fabric and heat-sealed seams, which block particle escape. It passes the ASTM D4726 sift test (less than 0.1 grams of leakage per square meter under standard pressure).


How does the TYPE C conductive feature work?

TYPE C bags use conductive fibers to create a path for static charge dissipation. They must be grounded via a copper grounding clamp (resistance <10⁶ ohms) during filling/unloading to prevent sparking—never use without proper grounding.


Can it be reused?

Yes, it can be reused 2–3 times after inspection. Conductive components should be tested for continuity (using a multimeter) to ensure resistance remains within 10⁴–10⁶ ohms; damaged fibers require replacement.


What is the temperature range for safe use?

It operates safely between -20°C and 60°C. Temperatures above 60°C may degrade PP fabric and conductive fibers, reducing performance.


Does it meet international safety standards?

Yes, it complies with IEC 61340-4-4 (electrostatic control) and ISO 21898 (FIBC safety), making it suitable for global industries with strict safety protocols.
