Overview Of Cardboard Takeout Boxes

Cardboard takeout boxes serve as convenient containers for transporting food. Their lightweight nature and ability to keep food contained make them popular among restaurants and consumers.

Materials Used In Cardboard Takeout Boxes

Cardboard takeout boxes often consist of several materials. These typically include:

  • Paperboard: This sturdy, recyclable material forms the main structure of the boxes. It provides durability while offering an eco-friendly option.
