Double-Layer Leak-Proof FIBC Bulk Bag

Leak-Proof FIBC for Solid Hazardous Waste Collection & Transfer

Double-Layer Leak-Proof FIBC Bulk Bags are designed for the collection, lifting, temporary storage and transportation of solid hazardous waste.

The bag combines a high-strength PP woven outer layer with an inner leak-proof PE film, creating a double-barrier structure that helps prevent liquid seepage and reduce the risk of soil and water contamination. UV-stabilized fabric supports temporary outdoor storage, while customizable liners, dimensions and hazard warning markings make the bag suitable for different hazardous waste handling requirements.

Key Features

Double-Layer Leak-Proof Protection

Hazardous waste may contain moisture or residual liquids that can seep through conventional woven bags. The combination of an outer PP woven bag and inner leak-proof PE film creates a double protective barrier.

The outer layer provides mechanical strength for lifting and transportation, while the inner film helps prevent liquid seepage and reduce environmental contamination risks.

Custom Leak-Proof PE Liner

Different hazardous wastes may have different corrosivity and containment requirements. The inner PE liner can be customized in thickness according to the characteristics of the waste, providing additional containment for sludge, waste residue and other solid hazardous waste.

UV-Stabilized for Temporary Outdoor Storage

The PP woven fabric is UV stabilized to provide additional resistance against sunlight-induced degradation. This makes the FIBC suitable for temporary outdoor storage. Prolonged exposure to direct sunlight should be avoided.

Efficient Filling & Discharge

The standard configuration features a small top filling spout and small bottom discharge spout. This design allows controlled filling and discharge without cutting or tearing the bag, helping improve hazardous waste handling efficiency.

Reliable 500kg Load Capacity

Four integrated lifting loops provide balanced load distribution during lifting and transportation. The standard configuration provides a 500kg Safe Working Load (SWL) with a 5:1 safety factor.

Stable 4-Panel Construction

The 4-panel construction provides balanced structural support and helps the bag maintain a regular shape after filling, improving placement and stacking stability during temporary storage and transportation.

Technical Specifications

Applications

Hazardous Waste Collection

Suitable for the collection and centralized handling of compatible solid hazardous waste generated by industrial production and waste treatment operations. The double-layer construction provides mechanical strength and additional leakage protection throughout the collection process.

Industrial Sludge

Suitable for applicable sludge and semi-solid waste where residual moisture or liquid seepage may be a concern. The inner leak-proof PE film provides an additional containment barrier to help reduce leakage during lifting and transportation.

Industrial Waste Residue

Designed for waste residue and other solid industrial waste requiring additional containment during collection, temporary storage and transfer. Custom liner thickness can be selected according to the characteristics of the waste.

Hazardous Waste Transfer

Suitable for transferring compatible solid hazardous waste between production sites, temporary storage areas and waste treatment facilities. Four lifting loops and controlled filling/discharge openings support efficient material handling.

Temporary Outdoor Storage

UV-stabilized fabric allows the bag to be used for temporary outdoor storage when required. For better service life, prolonged exposure to direct sunlight should be avoided.
