Storing liquids: Paper is not a suitable material for storing liquids. It is porous and will absorb the liquid, causing it to become soggy and unusable.
Building structures: Paper is not strong enough to be used for building structures. It will not withstand the weight of the structure and will collapse.
Insulating buildings: Paper is not a good insulator. It does not trap heat well and will not help to keep a building warm.
Electrical insulation: Paper is not a good electrical insulator. It will not prevent electricity from flowing through it and could cause a fire.
Medical packaging: Paper is not suitable for medical packaging. It is not sterile and could contaminate the medical supplies.
These are just a few examples of tasks for which paper is not suitable. Paper is a versatile material, but it has its limitations.
