Step-by-step explanation:
Density is defined as mass of a substance divided by volume of the substance.
Mathematically, Density =
As density is directly proportional to mass. So, more is the mass of a substance more will be its density.
And, more is the density of a substance more strength it will hold. And, when it will be used as a packaging material then it will not easily rip or tear apart.
As a result, it will keep the item or object safer.
On the other hand, a packaging material with low density can easily rip or can be crushed. So, it will not keep the item inside it safer.
Thus, we can conclude that a high density material makes better packing material.
