The development process involved extensive research into materials and construction methods. The paper used for these cups is a specially treated paperboard, chosen for its strength and ability to hold hot liquids without losing its shape. The inner layer is coated with a food-safe plastic lining, which not only prevents leakage but also provides a barrier against the heat, making the cup safe to hold even when filled with a hot drink.
