Square Bulk Bags: High Efficiency and Stable Stacking

FIBC (Flexible Intermediate Bulk Container): The formal technical designation under international transportation regulations and quality certifications, systematically defining their flexible structure and intermediate-scale bulk handling characteristics.
Jumbo Bags: Derived from their massive and load-bearing capability, frequently used in maritime bulk cargo transport for commodities like ores and grains. The term "Jumbo" emphasizes their visually imposing design.
Space Bags: Highlights space-saving characteristics. Their collapsible design makes them prevalent in Southeast Asian export regions for optimal container space utilization during bulk cargo shipping.
Bulk Bags: A generic term in European and American markets, directly denoting their primary application in transporting unpackaged materials (e.g., chemical powders, cereals), emphasizing functional purpose over structural specifics.
Ton Bags: Explicitly references the standardized weight capacity, commonly used in technical documentation and ISO standards to specify industrial-grade load specifications.

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).

We provide customized packaging solutions based on cargo properties, transport modes, and storage environments, covering end-to-end services from material selection to structural design. Below are the detailed workflow and core advantages:
● Needs Diagnosis Phase (1-2 working days)
1. Provide cargo parameters: density, particle size, corrosivity, hazardous class, etc.
2. Transport requirements: sea/air/land freight, etc.
3. Storage conditions: temperature, humidity, stacking tiers, etc.
4. Compliance certifications: FDA, UN, EU food-grade, etc.
5. If available, provide photos/videos of competing product packaging or existing issues (e.g., high breakage rate, difficult discharge) for targeted optimization.
● Solution Design Phase (3-5 working days)
We provide 1-2 tailored solutions (e.g., economy vs. premium protection), including:
1. Structural CAD drawings (with production process details).
2. Material comparison table: PP woven fabric gsm, PE liner thickness, certification levels, cost differences.
3. Performance parameter sheet: Modeled estimates for SWL test values, leakage resistance, UV resistance duration.
● Sampling Phase (7-10 working days)
1. Rapid prototyping: Deliver 1:1 physical samples (FIBC + liner combo).
2. Custom features: e.g., FIBC side inspection windows, static-dissipative liner coating.
3. Custom markings: Logo printing, batch number coding, hazard warning icons.
● Testing & Optimization Phase (5-7 working days)
Lab tests per your requirements:
- Lifting tests
- Drop tests
- Hermeticity tests
- Temperature resistance tests
- Puncture resistance tests
- UV aging tests
- Stacking compression tests
- Compliance spot checks
(Test fees negotiable)
● Solution Confirmation Phase (1-3 working days)
Final delivery: Sign 《Packaging Solution Confirmation Form》 including:
- Final stamped drawings
- Quality Commitment Letter (mass production ≤3% deviation from samples)
- Cost optimization proposals (e.g., alternative liner materials: 12% cost reduction with 20% protection decrease).
