WHAT IS BURSTING STRENGTH IN TERMS OF PACKAGING?

Bursting strength, in terms of packaging, refers to the ability of a material, such as paper, paperboard, or other sheet materials, to withstand burst or rupture under pressure. It is a measure of the maximum force or pressure that a material can resist before it bursts.

Bursting strength is an important property in packaging because it ensures the durability and integrity of packaging materials during handling, transportation, and storage. Packaging materials with higher bursting strength are more resistant to external forces such as compression, impact, or stacking, which helps protect the contents inside. 

By determining the bursting strength of materials used in packaging, manufacturers can select appropriate materials for specific applications and ensure the packaging can withstand the expected stresses and strains during its lifecycle. This helps prevent potential damage to the packaged products and ensures that they reach the end-user in good condition.

Bursting strength is typically measured using a device called a bursting strength tester, like the Mullen bursting strength tester. The results obtained from these tests are expressed in pounds per square inch (psi) or kilopascals (kPa), depending on the regional standard or preference.
