Clamshell packaging is packaging with two shell-like halves that are connected on one side and folded over itself, giving it a clam-like appearance. Though often made of plastic, it can also be made from different materials, such as molded pulp, paper, styrofoam, and more. They can be a generic box-like shape or thermoformed around a specific object.
Using clamshell packaging is intuitive, making it easy for consumers to open and close the plastic as they please. When made of clear plastic, clamshell packaging can help to provide a secure protective barrier while allowing the product within to be seen. Clamshell packaging is often used in packaging food, while thermoformed ones are often used in packaging electronic goods.
