ECT-48 Boxes: The Features and Benefits

At one point or another, your company has almost certainly used corrugated boxes to package, store, or ship products. While it may seem like pretty much every box is just about the same as the next one, this is rarely the case. Lightweight, poorly constructed boxes can tear during transit or be quickly damaged by a bulky item. Thankfully, heavy-duty ECT-48 boxes are here to help. 

What are ECT-48 Boxes? 

ECT-48 boxes, which are also commonly referred to as 48 ECT boxes, are heavy-duty corrugated materials that boast high-strength double wall construction. They come in a wide variety of sizes that can accommodate many different products, but each and every one of them offers outstanding benefits. 48 ECT corrugated boxes provide twice the amount of protection as a standard carton, as well as much better stacking strength, making them an excellent choice for goods that will eventually be stacked or palletized.  

Double Wall Box Construction 

One of the most important features of an ECT-48 box is its durable double wall construction, but what is it that makes double wall materials so beneficial? Simply put, they offer twice as much strength as a single wall box. So what exactly does double wall mean? A double wall carton is composed of three sheets of fiberboard and two layers of corrugated flutes all placed in a stack. Conversely, single wall boxes only have two sheets of fiberboard and one layer of corrugated flutes. Double wall boxes allow you to securely pack and ship bigger, heavier products without worrying about breakage during the shipping and handling processes. Additionally, heavy-duty corrugated boxes are 100% recyclable, meaning you can feel good about your impact on the environment.  

ECT Box Testing 

ECT stands for Edge Crush Test and is one of the most popular methods of determining the actual strength of a corrugated box or other corrugated material. The Edge Crush Test measures the actual stacking strength of a given carton by pressing part of the board’s edge between two rigid plates that face perpendicular to the flute direction. This shows how many pounds per inch the box is able to handle on its load bearing edges. ECT values most often range from 32-48, with 48 ECT boxes being the strongest. Ultimately, edge crush testing shows us two things: box compression strength and stacking strength.  

It’s important to note that there is another common type of box testing called Mullen Burst Testing that you will frequently see mentioned along with the ECT number. Instead of measuring a box’s stacking strength, burst testing determines how much pressure can be applied to the flat side of a corrugated board before it bursts or puncturesThis type of test is measured in pounds and will be reported in the style of 200#, 275#, etc.  

Heavy-Duty Boxes for Heavy-Duty Products 

As previously addressed, ECT-48 cartons are constructed using double wall corrugation. Because of this extra strength, these boxes are specifically intended for heavy or bulky products, as well as items with odd angles and edges. They can also be stacked on top of one another while sitting atop a pallet without losing their integrity or durability. Overall, ECT-48 heavy-duty boxes and corrugated material are an excellent way to protect, package, store, and ship all kinds of products that need the ultimate protection.
