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.

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.
