Plastic water cups are a common type of drinking container, usually made of plastic materials such as polyethylene (PE) and polypropylene (PP). They have the characteristics of being lightweight, durable, and not easily broken, and are widely used in places such as homes, offices, and schools.The appearance of plastic water cups is diverse, with various colors and patterns to choose from, such as transparent, semi transparent, and colored. They also come in various sizes, such as 500ml, 750ml, 1000ml, etc., to meet the needs of different populations. In addition, the plastic water cup also has a leak proof design, which can effectively prevent liquid leakage and keep the desktop clean and tidy.

   However, plastic water cups also have some drawbacks. Firstly, they may contain harmful substances to the human body, such as bisphenol A (BPA), and long-term use may have health effects. Secondly, plastic water cups are prone to deformation or release harmful substances in high-temperature environments, making them unsuitable for holding hot water or brewing tea. Finally, plastic water cups have poor environmental performance, are not easy to degrade, and are prone to causing environmental pollution.
