Force requires to burst or complete rupture of the Paper/ board is measured visually. The bursting strength value is expressed in terms of kgs/cm2. The bursting strength defines the materials quality compare to the others. The value of the bursting strength will give the indication that how much weight may be carried in the Paper/box.

Definition : This method measures the force perpendicular to the plane of the paper required to tear multiple plies

through a specified distance after the tear has been started using an Elmendorf-type tearing tester. The measured results can be used to calculate the approximate tearing resistance of a single sheet.

of an Elmendorf-type tearing tester. The work done in tearing is measured by the loss in potential energy of the

pendulum. The average force exerted when a certain number of plies are torn together (work done divided by the total distance torn).
