Blown FilmsIn thermoplastic film production thick films are produced like sheets by flat extrusion method. Thin films are generally blown fims. In Extrusion Blow Moulding the thermoplastic material is extruded across a cylindric core while in its center air is injected. So a thin wall hose is produced. The hose maintains its cylindric shape by air pressure un [..]
