Cardboard is a versatile material made from recycled paper pulp that is used for a variety of purposes, including packaging, construction, and art. It is strong, lightweight, and inexpensive, making it an ideal material for a wide range of applications.
The process of making cardboard begins with the collection of waste paper, which is then pulped and mixed with water to create a slurry. The slurry is then poured onto a conveyor belt and passed through a series of rollers, which press out the water and form the cardboard into sheets. The sheets are then dried and cut into the desired size and shape.
