Open Top Bulk Bags - Heavy-Duty & Customizable Colors

FIBC (Flexible Intermediate Bulk Container) is a large flexible packaging container made of polypropylene woven fabric, designed to carry bulk materials ranging from 500kg to 2000kg, such as chemicals, grains, and minerals. Its core functionality revolves around the unitized transportation concept, fundamentally transforming fragmented packaging models into integrated unit-load systems. By establishing standardized unitized containers, FIBC enables integrated lifting operations via cranes or forklifts, eliminating manual disassembly processes. For example, a truckload of cement traditionally requires hundreds of separate bags for manual handling, whereas FIBC systems accomplish full vehicle loading through single-lift operations, significantly improving efficiency.

Manufactured through polypropylene resin melting, filament drawing, fabric weaving, and sewing processes, FIBC maintains structural integrity under multiple times of rated load impacts during transit. Additional material modifications or structural enhancements enable specialized functions: moisture-proofing for grain storage to prevent mildew, anti-static liners for calcium carbide transportation to avoid explosions, and UV-resistant coatings for outdoor applications.

When empty, FIBCs can be compactly folded, reducing storage space. Reusable variants further enhance cost-effectiveness and environmental sustainability compared to single-use packaging. Serving as "flexible containers," FIBCs standardize bulk cargo handling across scenarios from port terminals to construction sites, resolving efficiency and cost challenges in loose material logistics through mechanized operations.

To ensure custom FIBCs meet your operational requirements, we recommend providing physical samples or technical drawings of your existing FIBCs for precise replication. If unavailable, please supply the following key parameters:

● Basic Dimensional Parameters
1. Overall FIBC length/width/height (cm or mm): e.g., 90×90×110cm or 900×900×1100mm.
2. Number, position, and length of lifting loops/straps: e.g., 4/2 loops; single-side/cross-corner loops (specify corner spacing), loop depth (30cm/50cm/full-base), loop length (25cm/40cm).
3. Bag type: U-panel, square, circular/tubular, duffle top, pallet-free, etc.
4. Liner requirement: Single/double liner (e.g., PE liner/foil liner).
5. Material selection: Polypropylene (PP). Specify:
- Calcium carbonate masterbatch ratio.
- UV inhibitor/anti-static agent requirement and ratios.
- Conductive threads requirement.
- Coating requirement (e.g., laminated).
6. Base fabric density: Standard range 120-260g/m².
7. Structural design:
- Top: Full open top/filling spout (specify diameter/length).
- Bottom: Flat bottom/discharge spout (specify diameter/length).
- Closure: Tie ropes/buckles/other sealing devices.
- Internal reinforcements: Lifting straps/load-bearing webbings required?
- Ventilation: Air vents required?

● Load Capacity & Safety Requirements
1. Safe Working Load (SWL): Design load per bag (e.g., 1000kg, 1500kg).
2. Safety factor: Required safety ratio (e.g., standard 5:1).

● Functional & Operational Context
1. Cargo characteristics: Material type (granules/powder/blocks), hazardous goods (compliance with transport standards), food/pharmaceutical hygiene requirements.
2. Environment: Storage/transport temperature range (e.g., -20℃~+60℃), exposure to water/oil/chemicals, outdoor UV resistance level.
3. Reusability: Single-trip or multi-trip FIBC (affects fabric thickness/seam construction).

● Marking & Customization Requirements
1. Printing content: Custom logos/text/warning symbols (e.g., "Keep Dry"/"This Side Up"), colors (provide Pantone codes/artwork), print position (front/side/top).
2. Mandatory markings: SWL/batch number/production date, or compliance with ISO/UN certifications.

● Additional Reference Information
1. Existing samples: Provide used FIBC samples/high-resolution photos (front/side/bottom/loop details) for replication/optimization.
2. Standards compliance: National (e.g., GB/T 10454-2000) or international standards (e.g., EN 1898, ASTM D5638).
3. Certification requirements: Needed/previous certifications (e.g., GRS – specify early for production alignment).
4. Bulk order details: Order quantity, delivery schedule (batch deliveries acceptable), packaging method (bundled/palletized/bundled + container bag).

As an FIBC manufacturer, we prioritize customer needs. Minimum Order Quantity (MOQ) adjusts flexibly based on product specifications, customization requirements, and shipping solutions:

I. Flexible MOQ Adaptation Principles
Our MOQ depends on these factors with no fixed standard:
1. Product type:
- Standard FIBCs (regular dimensions/basic SWL/no special features): Support small trial orders for new customers.
- Custom FIBCs (special shapes/anti-static/moisture-proof features/printed logos): MOQ evaluated based on base fabric density/width adjustments, process complexity, and shipping efficiency.
2. Shipping & cost optimization:
- FCL shipments (20GP/40HQ) vs. LCL shipments have significantly different MOQs.
- We recommend optimal loading solutions per destination port (e.g., Southeast Asia/Middle East/Europe).
- Long-term partners enjoy lower MOQs with batch deliveries or zero-inventory supply chains.
3. Compliance requirements:
- Food-grade/hazardous material FIBCs require certifications (e.g., FDA/UN).
- MOQ adjusts based on certification costs and production efficiency.

II. Recommended Communication Steps for Precision Solutions
1. Share basic requirements:
- Contact via phone/email with FIBC type, target SWL, destination port, and special needs (e.g., printing/features).
- Provide existing samples/design drawings for technical feasibility assessment.
2. We respond within 24 hours:
- Standard FIBC: Minimum trial order quantity and unit price (including estimated sea freight).
- Custom FIBC: Recommended MOQ (with cost breakdown: molds/certifications).
- Logistics comparison for different order volumes.
3. Risk mitigation & services:
- Trial orders include free sample testing (customer pays freight) for application validation.
- Bulk orders include production tracking, logistics planning, and destination port clearance support.
