HDPE (High-Density Polyethylene) is a strong and rigid type of plastic made from ethylene. It has a high density, which makes it tougher and more durable than LDPE and LLDPE.It is known for its high strength, hardness, and resistance to chemicals and moisture, making it suitable for heavy-duty use. HDPE is widely used in products like water pipes, bottles, containers, crates, and industrial packaging.Although it is less flexible than LDPE, it is more durable and long-lasting, which makes it ideal for both household and industrial applications.
