A Styrofoam cup is a disposable container made from expanded polystyrene foam, known for its lightweight and insulating properties. These cups are commonly used for hot and cold beverages, providing a convenient option for both consumers and businesses. They are often found in coffee shops, fast-food restaurants, and at events. The design of a Styrofoam cup typically includes a rolled rim for easy sipping and a sturdy base to prevent spills. While they are popular for their convenience, concerns about environmental impact have led to increased scrutiny and efforts to find more sustainable alternatives in recent years.
