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.
