What is elongation at break?
Elongation at break measures how much a material can stretch before it fractures. Expressed as a percentage of the original gauge length, it is a key indicator of ductility and toughness.

What is the edge crush test and why is it important?
ECT assesses the capacity of corrugated board to withstand compressive forces along its edge. A higher ECT value generally means the board has greater stacking strength.
