PP (polypropylene) is a common, food-grade safe material characterized by high chemical stability and a heat resistance of up to 110°C.
PP baby bottles also offer a range of practical features: they are lightweight-making them easy for babies to grasp-and feature a translucent body that allows for convenient monitoring of the liquid volume. Furthermore, their smooth surface makes them easy to clean, and they are economically affordable. The material possesses excellent toughness, making it drop-resistant and highly resistant to impact. However, after prolonged use-particularly following frequent high-temperature sterilization and scrubbing-the bottle body may become cloudy or retain milk residue; therefore, it is recommended to inspect and replace the bottle periodically.
