Strength
Cardboard boxes (Corrugated Fiberboard) are rated by an industry standard known as the ECT (Edge Crush Test). This indicates the pounds per square inch the board standing on edge can withstand. A standard moving box has a rating of 32 pounds per square inch before crushing, therefore would have a 32 ECT rating.
Ratings You Can Choose
No Test - really light - 26 ECT - light
