👉 Polypneic is a type of plastic used in packaging and manufacturing. It is made from a combination of high-density polyethylene (HDPE) and low-density polyethylene (LDPE), which are both synthetic materials. The HDPE is denser than the LDPE, making it more durable and resistant to heat and pressure. This allows polypneic to be used for packaging in a wide range of applications, such as food and beverage containers, medical devices, and cosmetics.
