Benefits of Edge Crush Test


Standards: ECT helps the supplier to determine whether the manufactured box complies with industry rules and customer’s requirements. Customer’s can determine whether the chosen material visually whether it meets the required demands.


Material testing: ECT allows the producers to check the strength of corrugated box. Producer can test the quality of materials used in the production.



Bursting Strength Test


Bursting Strength Test checks the toughness of the walls of the corrugated board when subjected to pressure. For testing, a rubber diaphragm is used to apply pressure to the walls until it bursts. The diaphragm is expanded using hydraulics and as the diaphragm expands, the corrugated board bursts under pressure. Meanwhile, the data will be record and analyze for determine the material to be produced.
