Pizza boxes are typically made from paperboard or corrugated cardboard, which are both types of paper-based materials.

Paperboard is a thicker and more rigid type of paper that is often used for the lids or tops of pizza boxes. It is lightweight, recyclable, and provides a smooth surface for printing company logos and other branding information.

Corrugated cardboard is a stronger and more durable material than paperboard, and it is commonly used for the bases or bottoms of pizza boxes. It consists of several layers of cardboard with a fluted middle layer that provides additional strength and insulation. This material is ideal for transporting pizzas as it provides protection against damage, while also maintaining the temperature of the pizza during delivery.

Both paperboard and corrugated cardboard are environmentally friendly and can be recycled. They are also biodegradable, which means they can break down naturally without causing harm to the environment. However, pizza boxes cannot be recycled if they are soiled with grease, cheese or other food residue, as it can contaminate the recycling stream. Therefore, it is important to dispose of used pizza boxes correctly by placing them in the trash or compost bin
