Boxes come in many materials. Some are made of wood or metal. Others use corrugated fiberboard. This is a strong paper material. 
You can close a box in many ways. Some have flaps or doors. Others have a separate lid. You can use tape or string to shut them. Some even have locks or clasps.
Some boxes are for special jobs. A jewelry box holds small jewels. A hat box can be round or oval. A toolbox helps you carry tools. A humidor is a box that keeps cigars at the right humidity. A strong box is a safe for money. Some boxes are made to be pretty. People keep these on display.
A box is a container with stiff sides. 
There are many ways a box can work. You can close a box with flaps or doors. Some boxes have a separate lid on top. You might use tape or string to keep it shut. Some boxes use catches, clasps, or even locks. 
Many types of paper boxes are made in stages. Folding cartons are paperboard boxes with a folding lid. 
Different materials make boxes better for certain tasks. Wood and metal are very durable materials. Crates are heavy-duty shipping containers often made of wood. A wooden box is rated by the weight it can carry. A crate is different because it must have all six sides. Metal ammunition boxes are used to hold ammunition. Large steel shipping containers help move goods around the world. These help with the global trade of many items.
You probably use many kinds of boxes every day. A jewelry box might hold tiny trinkets or jewels. 
A box is a container characterized by having rigid sides. 
To function as a container, a box must have a way to enclose its contents. This can be achieved through various closing mechanisms. Some boxes use simple flaps or doors to seal the interior. Others utilize a separate lid that sits on top of the structure. To keep these closures secure, people use adhesives, tapes, or string. More complex or decorative boxes may employ specialized hardware like catches, clasps, or even locks. 
In the world of packaging, corrugated boxes are vital shipping containers. These are constructed from corrugated fiberboard and are frequently called cartons, cases, or cardboard boxes. They are often used to transport products from warehouses during the distribution process. These containers are rated based on their carrying capacity or the strength of their material. They also serve as product packaging or as displays at points of sale. 
Paperboard boxes follow different manufacturing processes depending on their intended use. Folding cartons are paperboard boxes that feature a folding lid. The process begins by printing the design on the material if necessary. Next, the paperboard is die-cut and scored to create a flat blank. These blanks are transported and stored in a flat state to save space. They are only constructed into a box shape at the point of use. 
Another type of paperboard container is the setup box, also known as a rigid paperboard box. These are made from stiff paperboard and are permanently glued together using printed or colored paper skins. Unlike folding cartons, setup boxes are assembled at the point of manufacture. They are transported already constructed, which is why they are called "set-up." Because they are more expensive, they are typically used to protect high-value items like watches, cosmetics, or small electronics.
Heavy-duty shipping requires more durable materials like wood or metal. Crates are heavy-duty containers that are distinct from standard wooden boxes. While a wooden box's strength is rated by the weight it can carry before the top is installed, a crate must have all six sides in place to reach its rated strength. Metal ammunition boxes are also used to hold ammunition safely. On a much larger scale, the invention of large steel intermodal shipping containers has helped advance the globalization of commerce.
Many boxes are designed specifically for permanent storage and can be quite decorative. A jewelry box is used for trinkets or jewels and may be lined with satin or covered in leather. A hat box is used for transporting headwear and is often shaped as an oval or a cylinder. Other specialized boxes include the humidor, which maintains the proper humidity for cigars, and the toolbox, which is designed for portability. 
Security and organization are also key roles for different box types. A strong box, or safe, is a lockable container used for money or valuables. Some strong boxes are portable, while others are installed directly into a floor or a wall. In office settings, a box file is used to organize papers and small files. Even a toy box serves a specific organizational purpose by storing playthings. Each of these specialized containers demonstrates how the simple concept of a box can be adapted to almost any human need.
