Measurement of bursting strength with bursting strength formula

When we think of delivering quality packaging material to our customers then it is very important for you to test different properties of it. One of the most important properties that you can test is the bursting strength. It is known as the rate at which the packaging material will burst under certain pressure. The boxes with high bursting resistance will easily sustain well and can be used in the packaging of material. Whenever we are going to calculate the bursting strength of the material, then we need to take care of factors like bursting strength, factor and index.

Using this below mentioned bursting strength formula, you can easily calculate bursting factor and index:

Bursting Factor: Burst strength (gf/cm2) / Grammage (gf/m2)

Bursting Index: Burst strength (kPa) / Grammage (gf/m2)

In these formulas, different abbreviations have different meaning:

  • kPa = kilopascal
  • Kgf = kilogram force
  • Gf = Gram Force
  • Grammage = Base weight in units of gf/m2
