How to Choose the Right Box

Did you know that not every box is the same? The certification stamp at the bottom of the box is full of valuable information. Here's a helpful guide to help you determine if the box you have is right for your shipment.

The Mullen Test

The Mullen Test measures the wall strength of a box by determining how much pressure it takes to puncture or rupture the wall of a box, hence the term burst test. This is very important to keep in mind when choosing a box, especially if you are placing loose or oddly-shaped objects in the box.

This quite simply is who manufactured the box.

Advises how the box has been constructed. Single wall is most common and will consist of 3 pieces of paper that have been corrugated together; however, double and triple wall boxes offer more strength and support.

This refers to the test which measures the box's resistance to puncture, instead of its stacking strength.

This refers to the total weight of the manufactured liner before it's cut down into boxes. In the above example, the total weight of the non-cut liner would be 84 pounds per thousand (M) square feet.

This means the outside dimensions of the box cannot exceed 75 inches when added together.

This will tell you the maximum weight of the contents that you can place in the box.

This indicates where the box was originally manufactured.

Edge Crush Test

The stacking strength of a box is measured using the Edge Crush Test (ECT) and helps determine how much pressure the box can handle before being crushed. Since boxes are generally stacked when shipped, this the ideal strength test for shipping individually boxed products and merchandise.

This quite simply is who manufactured the box.

Advises how the box has been constructed. Single wall is most common and will consist of 3 pieces of paper that have been corrugated together; however, double and triple wall boxes offer more strength and support.

Edge Crush test measures the stacking strength of a box and is very important to keep in mind since packages are stacked when shipped. The 32 lbs/in refers to the weight per inch that can press down on the corrugated box before it buckles.

This means the outside dimensions of the box cannot exceed 75 inches when added together

This will tell you the maximum weight of the contents that you can place in the box.
