Introduction of Mullen Burst Test

-

Since the approval of corrugated board as the valid shipping materials in 1903, the corrugated boxes have played an important role in the products shipping, distribution and storage. To ensure the strength, the Mullen test, i.e., Burst Strength test, Burst test was developed.


The Mullen test is a measure of the force, or the pressure that is required to puncture or rupture the face, or wall of the corrugated board. This burst strength data is got by the Mullen tester, in pounds per square inches (200# Test, 275# Test, etc.). The most commonly used corrugated carton conforms to the 200# Test. The higher the number, the stronger the corrugated box.
