Double Wall Insulation

Pronunciation: (duhb-uhl wawl in-suh-ley-shuhn)

Double wall insulation refers to a design in foodservice packaging where two layers of material create an air pocket between them. This structure enhances thermal insulation, keeping hot beverages warm and preventing the exterior surface from becoming too hot to handle. Commonly used in disposable coffee cups, double wall insulation eliminates the need for separate sleeves and provides a comfortable grip for consumers.
