Cardboard is a versatile and durable material made from recycled paper pulp. It is lightweight, inexpensive, and easy to work with, making it a popular choice for a variety of applications, including packaging, construction, and art projects.
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 to remove excess water and form a continuous sheet of paper. The paper is then dried and pressed to create a strong and durable material, depending on its intended use and performance characteristics.
