Edge Crush Test (ECT)
Edge crush test (ECT) is a laboratory test used to measure and determine the ability of a corrugated cardboard sheet to resist crushing forces. It can be stated that the higher the quality of the carton box, the higher the resistance of the carton box to crushing force. For customers who are looking for carton boxes to pack heavy items, double wall carton boxes are recommended as they have high resistance to crushing force.
Vertical force is exerted along the edge of the carton box
