The industrial packaging sector faces dual pressures: the need for ever-stronger materials and the imperative of sustainable practices. At VidePak, we’ve spent 17 years engineering FIBC bags that meet both challenges, leveraging our team’s 150+ years of collective expertise. This report explores two critical dimensions: 1) The technical relationship between denier values and load capacities in our jumbo ton bags, and 2) The environmental benefits of using recycled materials in compliance with global regulations.
Denier Engineering: Strength Meets Economy
1. Denier-to-Load Capacity Dynamics
Our jumbo ton bags utilize polypropylene tapes with denier ranges of 1,200D–1,800D, customizable up to 2,500D for specialized applications. Denier (grams per 9,000 meters) directly impacts:
- Tensile Strength: 65–85 MPa for 1,200D vs. 90–110 MPa for 1,800D
- Elongation: 18–22% for 1,200D vs. 12–15% for 1,800D
- Abrasion Resistance: 500–800 cycles (ASTM D4157)
ASTM Compliance:
- 1MT Bags: 1,200D minimum (ASTM D5335)
- 2MT Bags: 1,500D minimum (ASTM D6414)
- 3MT Bags: 1,800D minimum (ASTM D7744)
Engineering Recommendations:
| Load Capacity | Minimum Denier | Fabric Weight | Safety Factor |
|---|---|---|---|
| 1 Metric Ton | 1,200D | 160 g/m² | 5:1 |
| 2 Metric Tons | 1,500D | 220 g/m² | 6:1 |
| 3 Metric Tons | 1,800D | 280 g/m² | 7:1 |
Case Study:
A South African mining company using our 3MT jumbo bags achieved:
- Load Integrity: 100% pass rate in 1.8m drop tests (ASTM D7744)
- Cycle Life: 15+ trips before retirement
- Cost Efficiency: 22% lower cost-per-trip than steel containers
