Many customers are unfamiliar with SF5:1 and SF6:1 when buying ton bags; in fact, these are the most critical safety indicators.
As a professional manufacturer, Foshan Hongyun Jiangtian Packaging explains in simple terms:
Safety Factor = Breaking Strength ÷ Rated Load.
SF5:1: Rated load 1 tonne, breaking strength ≥5 tonnes, suitable for general materials.
SF6:1: Rated load 1 tonne, breaking strength ≥6 tonnes, suitable for hazardous chemicals, mineral powders, and heavy materials.
According to the Chinese National Standard GB/T 10454-2020, bags for hazardous chemicals must have an SF6:1 safety factor.
We can help you select the appropriate safety factor free of charge based on your material, avoiding potential safety hazards.
