Grey paperboard, also known as grayboard or chipboard, is a type of paper-based material characterized by its sturdiness and versatility. It is typically composed of multiple layers of recycled paper fibers bonded together, with a gray or greyish color appearance due to the use of unbleached or partially bleached fibers. One of the key features of grey paperboard is its durability and strength relative to its thickness. Despite being thinner than many traditional cardboard materials, grey paperboard maintains a high level of rigidity, making it suitable for various applications where structural integrity is essential.
