Why do we need an Edge Crush Test when Box Compression is checked?

Carton or corrugated box packaging is the primary choice of millions of manufacturers worldwide. The difference you might have from others is how strong your cartons are in staying intact for longer. To ensure the same, you must have checked the ability or resistant strength of your boxes under commonly used compression tests. But have you checked the Edge Crush Strength or ECT of the cartons? Many of you might nod to NO. This blog comes straight from the experts of quality control in the packing industry and will help understand why evaluating the ECT is important also when the compression test has already been done.

What does Box Compression tell you about the carton?
The box compression test compresses the carton using a vertical force. A compression plate coming from the top exerts pressure and slowly the box starts crushing and deforming. The level at which the box starts deforming is calculated and displayed. In this test, you only get one strength aspect of the box which is its overall strength. Also with this test, you can test the ability of the assembled carton and not every element or a single part of the carton like its edges.

How Edge Crush Tester can help?
Edge Crush Test using an ECT tester helps evaluate the Quality of the edge of the box. Now you might think that if the entire box has the strength to resist the external forces then why do I need to test the edges? Take it this way you might be overall healthy but a few of your organs or a particular bone if not functional properly will lead to health complications later on. Similarly, the edges of the corrugated cartons are the structure or bones of the box. If the edges are strong which is the base, the box will have more strength. Test the resistance strength of the edges under crushing forces will help you know how your boxes will behave when they will experience the external forces to the edges.
