Strength Testing

The corrugated cardboard industry has two standards for testing the strength of a box: the Mullen Test and the Edge Crush Test.

The Mullen Test measures the bursting strength of corrugated boxes. In other words, it tests the amount of pressure or force needed to rupture the wall of the box. Boxes that pass this standard are rated with the appropriate # or lb designation – 200#, 275#, etc.

The Edge Crush measures the stacking strength of corrugated boxes or the amount of pressure a box can withstand before being crushed. Boxes are rated accordingly with the ECT designation — 32 ECT, 44 ECT, etc.

A box is just a box, right?

Well, not quite — at least, not when it comes to keeping your products safe and making sure that you don’t pay more for shipping than is necessary.

There are many corrugated boxes to choose from when shipping your products, but the two most common are the 32 ECT and the 200# test box. So, how do you decide which one to use?

Keep reading to learn more about how these two packaging options compare — and which one is best suited to your shipping needs.

Which Box Is Best?

In general, the 200# test box and the 32 ECT corrugated boxes are interchangeable. But because stacking strength has become the most important factor for most warehouses today, many opt for the 32 ECT.

We recommend considering your priorities carefully before selecting your box of choice: if you anticipate that your boxes will experience a great deal of wear and tear, then the best packaging solution for your products may be the 200# box since the corrugated walls hold up better to rough handling.

If your products will be shipped on pallets, then the 32 ECT box will likely be the better packaging choice, since the cardboard performs better when stacked.

The type of box you ultimately decide to use will vary based on the products you are sending and the way you ship them. If you have questions, contact Hongdu Paper to speak with our packaging experts, who can help you select the best packaging solution for your specific needs.
