Corrugated Strength Ratings

Edge Crush Testing measures the force applied in pounds per linear inch of loadbearing edge and is reported as an ECT rating 32 ECT is the most commonly used corrugated material ECT has grown in popularity since its invention in the 1990s because it provides a better measure of how well boxes will hold up to stacking and palletizing
