The formula for Bursting Factor (BF) is calculated by dividing the bursting strength of a material by its grammage (GSM).
In simpler terms:
Bursting Factor = Bursting Strength / Grammage (GSM)
Where:
- Bursting Strength: The measure of the material's resistance to rupture when pressure is applied.
- Grammage (GSM): The weight of the paper or material in grams per square meter.
