Polyethylene (abbreviated PE) or polyethene (IUPAC name polyethene or poly(methylene)) is the most common plastic. The annual global production is approximately 80 million tonnes.or common commercial grades of medium-and high-density polyethylene the melting point is typically in the range 120 to 180 Â°C (248 to 356 Â°F). The melting point for average, commercial, low-density polyethylene is typically 105 to 115 Â°C (221 to 239 Â°F).
