Industry Application Cases

Here is the strict sentence-by-sentence translation using FIBC industry terminology:  

In the chemical industry, FIBC selection must balance safety, corrosion resistance, hermeticity, regulatory compliance, and alignment with transport scenarios and material properties.  

● Material Selection & Performance Requirements  

1.  Prioritize polymer materials: PP base fabric, PE coating/liners.  

2.  Their chemical stability resists acids, alkalis, and organic solvents.  

3.  For flammable/explosive chemicals: FIBCs require anti-static additives or conductive threads for static dissipation to prevent sparks.  

4.  Employ high-density weaving to enhance base fabric tear resistance.  

5.  For heavy materials (e.g., plastic pellets, fertilizer): Select multi-layer reinforced constructions to ensure required safety factors.  

6.  Add UV inhibitors to extend service life in outdoor transport/storage, preventing material embrittlement.  

● Structural Design & Functional Adaptation  

1.  For powdered/liquid chemicals: Equip with inner liners, waterproof coatings, and sealed valves.  

2.  All seams require anti-leak cotton tape to prevent leakage during transit.  

3.  Top lifting is standard for loading/unloading.  

4.  For oxidation-sensitive or humidity-controlled materials: Adjust gas exchange via enlarged vent holes or lamination.  

● Compliance & Certification Standards  

1.  For hazardous chemicals: FIBCs must comply with UN Recommendations on the Transport of Dangerous Goods, including flame retardancy, hermeticity tests, and drop tests.  

2.  For food additives/pharmaceutical intermediates: Materials require FDA or EU 10/2011 certification for non-toxicity.  

● Selection Process Recommendations  

1.  Define material properties: Chemical nature (corrosivity/volatility), physical form (powder/granules/liquid), weight range.  

2.  Assess transport conditions: Distance, handling methods (forklifts/cranes), storage environment (temperature/humidity, outdoor/indoor).  

3.  Compliance verification: Confirm need for UN certification, anti-static, or food-grade qualifications.

Here is the strict sentence-by-sentence translation using FIBC industry terminology:  

Food-grade FIBCs play a critical role in grain storage, requiring designs that meet food safety, moisture/mold prevention, efficient handling, and long-term storage needs.

● Material Safety & Food-Grade Certification  

1.  Food-grade FIBCs typically use non-toxic polymers like PP or PE.  

2.  Products can obtain international food-contact certifications (FDA, EU 10/2011) per customer requirements.  

3.  Certifications ensure no harmful substance migration contaminates grains during transport/storage.  

4.  Inner layers may apply food-grade coatings to enhance moisture resistance.  

● Moisture/Mold & Pest Prevention  

1.  Grain storage is humidity-sensitive.  

2.  Food-grade FIBCs utilize multi-layer woven structures with waterproof membranes to block external moisture ingress.  

3.  This prevents grain moisture absorption and mold formation.  

4.  Adjustable vent holes balance internal/external gas exchange, avoiding condensation from excessive sealing.  

● Hermeticity & Long-Term Storage Adaptation  

1.  Liners employ heat-sealing processes to reinforce seam hermeticity.  

2.  This eliminates leakage risks during transport/stacking.  

3.  For long-term grain storage:  

- Integrate UV-blocking layers to slow nutrient degradation from light exposure.  

- Include document pouch labels recording storage duration, temperature/humidity for quality monitoring.  

● Structural Design & Handling Efficiency  

1.  Grain FIBCs require adaptation to mechanized operations.  

2.  Bottom load-bearing webbings and lifting loop construction withstand ≥1.6× Safety Working Load (SWL).  

3.  This accommodates high-frequency automated forklift/crane handling.  

4.  Square/cylindrical designs optimize warehouse space utilization.  

5.  Bottom discharge spouts enable rapid unloading, reducing manual intervention. 

In mineral transport, FIBCs must withstand abrasion, impact, and high-frequency handling of heavy/sharp materials like ores and coal. Selection focuses on material strength, structural design, and process details.  

● Base Fabric Material & Weaving Density  

1.  Mineral transport FIBCs prioritize base fabric abrasion resistance.  

2.  Typically use high-density PP fabric with ≥210g/m² gsm to resist ore edge wear.  

3.  Multi-layer cross-weaving increases surface density, reducing fiber cutting by ore edges.  

4.  Premium models use composite materials (e.g., PP+PE) to enhance tear resistance.  

● Structural Reinforcement Design  

1.  Bottom and edges require targeted reinforcement.  

2.  Bottom: X-pattern or grid-pattern base reinforcement with double-layer fabric or hot-melt coating to enhance wear resistance in load zones, preventing ore pile punctures.  

3.  Sides: Add abrasion-resistant strips to reduce friction damage from forklifts/containers during lifting.  

4.  Lifting loops: Width ≥70mm; use 4-loop + base reinforcement to distribute stress and prevent localized wear.  

● Coating & Surface Treatment  

1.  Inner PE film or polyurethane coating blocks direct sharp material contact, reducing puncture risks.  

2.  Exterior UV inhibitors extend service life in open transport, preventing material embrittlement.  

3.  Seams: Prioritize double-needle stitching to enhance reliability under heavy loads.  

● Functional Adaptation & Compliance  

1.  For metal ore powder: Embed conductive threads or add anti-static agents to prevent electrostatic ignition.  

2.  High-temperature environments (e.g., coking coal): Require flame-retardant certification.  

3.  Selection must comply with ISO 21898, ASTM D5638 for abrasion/load capacity.  

4.  Special scenarios require UN certification for dangerous goods transport.  

● Usage & Maintenance Guidelines  

1.  Handling: Forklifts must insert parallel through all four loops; avoid slanted dragging.  

2.  Ground dragging prohibited, especially on sharp surfaces like gravel.  

3.  Regularly inspect loop and seam wear; repair/replace promptly to avoid reuse failures.  

4.  Outdoor storage: Cover with UV-resistant tarps to slow material aging.
