How Strong Is A Heavy Duty Cardboard Box?

When you look at the humble cardboard box, you may not be confident of the strength of the material. It is made of paper and you can fold it or modify it with your hands. But do not be under the misconception that these are weak in any way. This is no ordinary packing material. Cardboard boxes are made with flutes which are present between the layers of the material. It is this arrangement which provides immense strength to the packaging material.

Did you know that at one point of time, these corrugated boxes were produced as an attempt to replace the wooden boxes completely? Before you become judgmental, let me clear the air. If you think that you can store heavy products in single corrugated boxes and expect it to bear the weight easily then you are mistaken. The packaging will give away in this case. There are special heavy duty shipping boxes that are designed specifically for heavy duty usage and these usually have three layers of flutes or a single layer of large sized flutes. This particular arrangement makes the material as strong as any piece of lumber.

As is evident from the above explanation, you need to find out the most suitable customized boxes for your specific needs. If you have heavy products then you should go for a tri-layered corrugated box or a dual layer box. For light weighted requirements, a single layered corrugated box would be more than sufficient. The material in itself is durable enough and can hold up to external forces but there should not be any wear and tear or damage on the material as this could prove to be a weakness.

Moreover the design of the box matters a lot also. If you consider an egg, you would believe it to be fragile. But if you were to apply pressure on its ends, then you would be amazed at the amount of force that it can bear. It has been known to support heavy objects when placed in the appropriate balanced position. The same applies to heavy duty shipping boxes. You may not be able to judge their strength by merely looking at it but when you see it in action, you would be amazed at the capabilities of this simple yet durable packaging material.
