Paper cups are disposable containers made primarily from paper and lined with either wax or plastic to prevent liquid from leaking out or soaking through the paper. They are commonly used for serving hot and cold beverages such as coffee, tea, soft drinks, and water in various settings including cafes, offices, parties, and events.

In summary, paper cups are convenient, versatile containers that play a significant role in the food and beverage industry. While their environmental impact is a concern, efforts are ongoing to improve their sustainability and encourage responsible use and disposal practices.
