Polyethylene is a lightweight thermoplastic made from hydrocarbons.

Low-density polyethylene (LDPE) is the most widely used plastic. It is relatively inexpensive, flexible, strong, and chemical-resistant, and can be molded molded into bottles, food packaging, and plastic toys. High-density polyethylene (HDPE) is stronger than LDPE and is made into products such as grocery bags, car parts, packaging, and piping.
