Plastic measuring cups are common measuring tools used in laboratories and industries, primarily for accurately measuring the volume of liquids. They are typically made of plastic materials such as polypropylene (PP), and are lightweight, chemically resistant, and not easily broken. The design of plastic measuring cups includes graduation lines, capacity markings, and a spout for easy pouring, making them suitable for various applications requiring precise liquid measurement, such as laboratories, chemical plants, and food processing plants.
