How To Use The Bursting Strength Formula For Corrugated Boxes

The corrugated box is one of the widely used testing instruments used in the packaging industry. Its quality matters the most in terms of holding the material for a longer time. The high-quality corrugated boxes can withstand the pressure and will not get burst easily. To test the bursting strength of these boxes, you can easily make use of the Testronix bursting strength tester. This is one of the highest quality testing instruments that provide you with accurate testing results.

We have different models of this testing instrument available to us. Here we will discuss the bursting strength tester digital model from Testronix and how you can calculate the bursting strength with the bursting strength formula.

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
