Technical Parameters of FIBC
Safe Working Load (SWL)
Safe Working Load is the maximum weight that an FIBC can safely carry under normal operating conditions.
Common specifications:
- 500 kg
- 1000 kg
- 1500 kg
- 2000 kg
Safety Factor (SF)
The safety factor is the ratio of the FIBC’s design load-bearing capacity to its safe working load.
Calculation formula:
SF = Burst Load / SWLNumber of Reuse Cycles
| Type | Cycle Count |
|---|---|
| Single Trip | 1 time |
| Multi-Trip | 5–30 times |
