Cardboard boxes include any box made from paper pulp-based material. Cardboard is usually naturally brown or greyish in color, though it can be bleached or painted. Because of cardboard's versatility, low cost, low weight and highly recyclable properties, it is among the world's most popular container construction materials.
Every commercial and industrial enterprise requires a means to store and ship products. Also, simple operational necessities like space management require the use of containers to keep office supplies, industrial ingredients and other supplies organized. Outside of the context of business, cardboard boxes are widely used in private homes for small-scale storage and during moving. Because cardboard boxes are inexpensive, and because in consumer contexts they can be used to store almost anything, they are among the most popular moving and storage tools available. The same is true for their popularity as shipping containers; cardboard boxes are widely used by manufacturers and distributors to transport their products to their customers. In addition to their capacity as storage and shipping materials, cardboard boxes can be used as containers for cereal and other free-flowing food products, produce, office supplies like staples and paperclips and for a wide variety of other small objects.
