Ripple paper cups, also known as corrugated paper cups or ripple wall cups, are a type of disposable beverage container designed to insulate hot or cold drinks and provide a comfortable grip for the user. These cups are made from paperboard and typically consist of three layers of material:

1. Outer Layer: This layer is usually made from a heavier-weight paper or cardboard material. It provides structural integrity to the cup and allows for branding and customization with printed designs or logos.

2. Middle Layer: The middle layer is the corrugated or ripple wall. It consists of fluted paperboard that creates an air gap between the inner and outer layers. This air gap helps to insulate the contents of the cup, keeping hot drinks hot and cold drinks cold while preventing the outer surface from becoming too hot to touch.

3. Inner Layer: The innermost layer of the cup is a thin, food-grade paperboard or PE (polyethylene) coating.
