The blow molding process began to be used to produce low density polyethylene vials during the Second World War. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology was widely used. The volume of hollow vessels can reach thousands of liters, and some production has been computerized.
