The test involves diligently cutting a sample of material and subjecting it into a leading load in the edge down configuration. The test gives a sign of the flexibility with the box manufactured with that material to withstand static and dynamic leading loading as would happen in the course of warehousing or distribution.
To get a presentation-model box (like a Tab Locking Box or Literature Mailer), you will likely want to select a board that’s very easy to fold, such as a B or E flute. Even though we make presentation boxes with thicker material, the folding and creasing can be a little more cumbersome.
A box with an ECT 32 ranking can withstand an edge crush power of around 32 lbs . per inch. Corrugated fibreboard, a type of material made up of a fluted layer sandwiched concerning two flat linerboard levels, is the material used for making ECT boxes.
It’s vital that you Be aware that there's A different frequent sort of box testing named Mullen Burst Testing that you will routinely see pointed out along with the ECT amount. Instead of measuring a box’s stacking energy, burst testing determines how much tension could be applied to the flat side of a corrugated board right before it bursts or punctures. This variety of test is measured in pounds and will be described from the variety of 200#, 275#, and so forth.
The Mullen test is just one of quite a few tests that are used to measure the toughness of corrugated cardboard boxes. A further frequent test is the Edge Crush Test (ECT), which measures the stacking strength of a box by examining its resistance to crushing when It is stacked underweight.
Nonetheless, you will need to consider more than simply the ECT. The size and type of box you decide on will likely Engage in an element. As an example, a 32C box can have extra weight than the usual 32E box mainly because it’s thicker.
Using cardboard boxes could involve bubble wrap, sheets, or loose fill to assist protected objects all through shipments, where corrugated boxes wouldn’t involve this.
We typically propose 32 ECT C or 44 ECT for RSC boxes, depending peladow calcium chloride upon the weight of the product shipped. We can make most custom shipping boxes from most boards, but we recommend ordering a sample very first.
If an ECT tester just isn't available, you can also execute a straightforward guide test. To start with, place the box with a flat surface and press down on the edges with your palms.

It’s crucial that you Remember that using a box with a better ECT rating than important may well lead to larger shipping costs.
A more recent standard which includes achieved widespread acceptance is the sting Crush Test (ECT). This is a correct functionality test and it is directly associated with the stacking strength of a carton. ECT is often a measure of the edgewise compressive power of corrugated board.
A Mullens 200# and ECT 32 are greatly considered as being interchangeable. Nevertheless they both equally have their benefits. Each individual fiberboard has a selected “Recipe” that results the power, weight, thickness, and also other Specific Qualities.
A piece of the corrugated material which makes up the box is placed on the edge. Then two plates, one particular on each side on the piece, push collectively, crushing the corrugated material concerning them.
