Paper is a material made mainly from wood pulp. It is used for writing, printing, and art work, to wrap things, and even to cover walls.
To make paper, woodchips are heated with chemicals, a process that turns them into pulp. The pulp is strained, washed, and put through a screen to remove any unwanted material. More chemicals are added, and the pulp is beaten until it is the correct texture. It is then put through a papermaking machine to form into sheets or rolls of paper. Finally, it is passed through heated metal rollers to give it a smooth finish.
