A paper cup sleeve is a protective cover typically made from paperboard or corrugated cardboard, designed to fit around a disposable paper cup. Its primary function is to provide insulation, preventing the cup from becoming too hot to hold when filled with hot beverages like coffee, tea, or hot chocolate.
Paper cup sleeves help to enhance the comfort of holding the cup, offering a convenient grip while protecting the hands from burns. They are eco-friendly, often made from recycled or biodegradable materials, and are an alternative to foam cup holders, which are harmful to the environment. Many paper cup sleeves can also be branded, allowing businesses to promote their logo or message. They are commonly used in cafes, restaurants, and fast-food establishments.
