The most common types of plastic used in the manufacturing of sport water bottles are polyethylene terephthalate (PET) and high-density polyethylene (HDPE). PET is a lightweight and durable plastic that is widely used for single-use bottles, while HDPE is a thicker and sturdier plastic that is often used for reusable bottles. Both PET and HDPE are food-grade plastics that are safe for storing and consuming water.
