Kraft paper is a strong, durable paper made from wood pulp through a process called the kraft process. This method involves cooking wood chips with chemicals to break down the fibers, resulting in a thick, brown paper that is often used for packaging, bags, and boxes. Its strength makes it ideal for holding heavy items. Kraft paper is also environmentally friendly, as it can be recycled and is often made from sustainable sources. It is commonly used in various industries, including food packaging, construction, and arts and crafts, due to its versatility and cost-effectiveness.
