Product Overview
Our Three-In-One Container Bag redefines durability for bulk packaging of high-specific-gravity and abrasive materials. Unlike single-layer container bags, it features a composite fabric structure combining force cloth (for tensile strength), flat cloth (for flexibility), and a reinforced inner liner—creating a “three-in-one” barrier that resists tearing, puncturing, and deformation. This design ensures the bag maintains its shape even when filled with heavy materials (e.g., metal pellets, ore, or concrete aggregates) and withstands rough handling during loading/unloading. With a high gram-weight fabric (≥200g/m²) and reinforced stitching at stress points (handles, seams), it’s engineered for industries where standard bags fail—delivering long-term reliability and reducing packaging-related downtime.
Scenario-Based Solutions
Mining & Mineral Processing
Mines transporting iron ore, copper concentrate, or granite chips need packaging that can handle abrasive, high-density loads (up to 2000kg). Our Three-In-One Bag’s composite fabric resists scratching from sharp mineral edges, while the reinforced seams prevent splitting during forklift handling. It also maintains its shape when stacked in shipping containers, reducing the risk of bag collapse and material spillage—critical for complying with transportation safety regulations (e.g., IMDG Code for hazardous minerals).
Metal & Foundry Industry
Foundries shipping metal pellets (e.g., steel shot, aluminum ingots) require bags that can support heavy weights without stretching. Our bag’s high tensile strength (2500N/5cm warp) ensures it doesn’t elongate under load, keeping pellets contained and preventing damage to pallets or trucks. The inner liner also acts as a barrier against rust, protecting metal products from moisture during ocean shipping.
Construction Material Logistics
Construction companies transporting sand, gravel, or concrete mix often face issues with bag deformation—leading to uneven stacking and wasted warehouse space. Our Three-In-One Bag’s rigid composite fabric maintains a uniform shape after filling, allowing for efficient stacking (up to 5 layers) and maximizing container/warehouse capacity. It also resists damage from construction site debris, ensuring materials arrive intact for on-site use.
Key Product Features
• Three-Layer Composite Fabric: Force cloth (tensile strength) + flat cloth (flexibility) + inner liner (barrier protection) = all-in-one durability.
• High Gram-Weight Fabric: ≥200g/m² woven PP fabric (standard) or ≥250g/m² (heavy-duty), ensuring resistance to abrasion and deformation.
• Reinforced Stress Points: Double-stitched handles (connected to bag body with metal D-rings) and heat-sealed seams, supporting SWL up to 2500kg.
• Shape Retention: Maintains 95% of its original shape after filling, enabling stable stacking and reducing storage space waste.

Customization Services
We tailor our Three-In-One Container Bag to your specific heavy-duty needs:
• Fabric Gram-Weight: Increase to 250g/m² or 300g/m² for ultra-abrasive materials (e.g., diamond dust, volcanic rock).
• Load Capacity: Reinforce with additional force cloth layers to support SWL up to 3000kg (for industrial machinery parts).
• Inner Liner Material: Upgrade to chemical-resistant PE (for corrosive minerals) or anti-static PE (for metal powders prone to static).
• Handling Features: Add extra handles (6 instead of 4) for multi-point lifting, or install RFID tags for inventory tracking in large-scale logistics.
• Branding: Print product specifications (e.g., “SWL 2000kg – Abrasive Resistant”) or company logos using weather-resistant inks for outdoor storage.
