A pizza box is a specially designed container used to hold and transport freshly baked pizzas from pizzerias, restaurants, or delivery services to customers' homes or other locations. These boxes are crafted to keep pizzas hot, fresh, and intact during transit, ensuring that they arrive at their destination in optimal condition for consumption.

Typically made from corrugated cardboard or paperboard, pizza boxes feature a square or rectangular shape with a flat bottom and tall sides to accommodate the size and shape of a standard pizza. The top of the box usually has a hinged or tuck-in lid that securely closes to keep the pizza enclosed and protected.

Pizza boxes are designed to be sturdy and durable to withstand the weight of the pizza and any additional toppings, as well as the rigors of transportation. The cardboard material provides insulation to help retain heat, keeping the pizza warm until it reaches the customer.

Many pizza boxes also include ventilation holes or vents on the sides or top of the box to allow steam to escape, preventing the pizza from becoming soggy while trapped inside. These vents help maintain the crispiness of the crust and the freshness of the toppings.
