Corrugated boxes are used to transport everything from food and beverage goods to electronics.
They’re reliable and they look and feel lightweight but have you ever stopped to think about just how strong they really are?
If so, then keep reading to learn about how much weight corrugated boxes can actually hold!
What Are Corrugated Boxes?
Corrugated boxes are made from three layers of cardboard that are bonded together by a starch-based glue.
These boxes are both lightweight and durable making packing and shipping an efficient process. Corrugated boxes are also biodegradable and help to save energy.
While these boxes provide a safe and secure way to transport goods, there are several types and styles to choose from. And each style can hold a different amount of weight.
Types of Corrugated Boxes
Boxes range from a single wall to triple wall style and all of them contain a different type of corrugated fluting depending on the size.
The fluting acts as the foundation of the box and is the main factor in what makes a box corrugated.
Flutes range in thickness with A flute being the thickest and F flute being the thinnest. C flute is the most common type used in shipping and is 3.5 to 4mm in thickness.
How Much Weight Can They Hold?
Now that we’ve gone over what these boxes are, we can finally look into how much weight they can hold. Corrugated boxes are very strong, but the answer to this question is going to depend on the size and type of box that you’re using.
A single wall box can hold between 20 – 120 lbs, double-wall boxes can hold 80 – 180 lbs, while triple wall corrugated boxes can hold between 245 – 300 lbs.
The boxes are a lot stronger than they appear and in fact, undergo a series of testing methods as part of the quality control process.
This all may come as a surprise but it is helpful to know just how strong each type of box is during the packaging process to avoid causing any damage to goods.
Corrugated boxes may look lightweight and some may even be small, but they are all extremely mighty.
These boxes weigh virtually nothing, as a medium-sized box weighs in at just under 0.03 pounds. Their lightweight feel is all a part of their construction since the flutes or grooves are designed to create more air space. This space provides a cushion for the box’s contents during transportation.
Not only are they durable, but they can be reused time and time again. The lifespan of a corrugated box is very long, and by understanding how much each box can hold will only help to further its life cycle.
These cardboard boxes make transporting goods easier and can last forever, as long as you don’t tear them apart when unpacking!
