Disposable paper cup manufacturers produce cups that are designed to be used only once and then thrown away. These cups are typically made from paperboard, which is coated with a thin layer of plastic to make them waterproof. The plastic coating also helps to prevent leaks and spills. Disposable paper cups are widely used in fast-food restaurants, coffee shops, and other businesses that serve beverages on-the-go. They are a convenient option for customers who want to take their drinks with them, but they can also contribute to environmental waste.
