Did you know the difference in box strengths??

We fully recognize and applaud the packaging experts who can, without hesitation, give a 3 minute dissertation on the difference between ECT32 and 200Test. (Insert Applause Here) BUT for those of you, whose minds have already started to wander…we offer some easily digestible facts aimed to make you a more informed consumer of corrugated boxes.
First, the basics. 
ECT32 and 200Test are simply two different industry standard names, used to define the measurement of strength of a corrugated box.  Think of inches vs. centimeters or liters vs. ounces. Both define the same physical measurement; they are just stated differently based on the metric system they are relative to.
Second, what are we measuring?
The Edge Crush Test, or ECT, measures how many pounds per square inch (lbs/inch²) a single corrugated box can support without crushing. Whereas, the 200Test or Mullen Test, measures how many pounds per square inch (lbs/inch²) are required to rupture/burst the side of a box, taking into effect both internal and external pressures that the corrugated box will absorb.  Therefore, an ECT32 corrugated box can withstand up to 32lbs per square inch before it crushes. In comparison, a 200Test corrugated box requires a force of 200lbs per square inch to puncture the side.
That sounds like fun in the physics lab but what about buying boxes?
When making a decision regarding purchasing ECT32 or 200Test corrugated boxes,  the systems used to measure the strength of each box are most relative to how the boxes will be transported or used.  Since an ECT measurement is relative to a box’s ability to withstand “crushing” under a particular weight, or their stacking strength; you would think Edge Crust Test if your boxes are stacked on a pallet, stacked in the back of a truck, stacked in a distribution center, sitting in a storage facility and/or in transit.  Comparatively, 200Test measures the handling ability of a corrugated box. So you would think 200Test when your boxes are thrown around, dropped, shaken, squished and/or moving in transit.
And now for the surprise inside! 
Now, before you go putting down your pencils to call your Wrap-N-Pack salesperson, there is one measurement left to discuss: Gross Weight Capacity. The scientific truth is that whether stacked, thrown, pushed or crushed, both ECT32 and 200Test corrugated boxes will perform with near identical results in the field.  Surprised? The reason – both boxes are designed to support 65lbs of gross weight capacity. The proof – look at the certificate stamp of the next corrugated box you receive. Wrap-N-Pack boxes are always clearly marked with the appropriate gross weight capacity.
