A plastic cup is a lightweight, disposable container typically made from various types of plastic, such as polypropylene or polystyrene. These cups are commonly used for serving beverages at parties, picnics, and events due to their convenience and affordability. They come in various sizes and colors, making them suitable for both hot and cold drinks. Plastic cups are often used in settings where glassware might be impractical or unsafe, such as outdoor gatherings or children's parties. While they are convenient, concerns about environmental impact have led to increased interest in reusable cups and biodegradable alternatives.
