A paper cup is a cup-shaped container manufactured by mechanically processing and gluing base paper (white paperboard) made from chemical wood pulp. Paper cups intended for frozen foods are wax-coated and suitable for holding items such as ice cream, jam, and butter. Those designed for hot beverages are plastic-coated; they can withstand temperatures above 90°C and are even capable of holding boiling water. Paper cups are characterized by their safety, hygiene, and convenience; they are disposable items widely used in public places, hotels, and restaurants.

Paper Cups: In China, cups made from paper materials are commonly referred to as "paper cups." Regulations have elevated the production management of paper cups to food-grade standards; consequently, manufacturers selling paper cups on the market must hold a QS (Quality and Safety) production license. The validity of the license number can be verified on the website of the national quality and safety supervision authority.
