Box Strength Test
There are several standards for the box strength in the corrugated box industry, including ECT, FCT, and CMT.
ECT means edge crash test. It shows the strength of handling ability. The test machine always presses the corrugated box’s edge, adds pressure onto until the box crush, then the weight transfer to ECT code. It is called ECT, like ECT32, ECT 44, ECT 56. Higher numbers mean good quality. If you are interested in this, we can make a demonstration for you.
FCT means a flat crush test. The box is flat when testing and get the FCT code. From this test, you can get to know what quality standard of your current cardboard. A Higher FCT number means more rigid of the corrugated fiberboard.
CMT means corrugated medium test, and it is a test for corrugated paper.
