Development of a blown tubular film extrusion die and air ring

This creative project has investigated the engineering principles relative to the design and fabrication of both a blown tubular film extrusion die and an air ring. The study has also made a careful analysis of the equipment necessary to construct a blown tubular film extrusion line.In addition, the creative project has discussed the origins of film extrusion, alternate methods of producing polyolefin films, and troubleshooting suggestions which can provide valuable assistance in the production of quality blown tubular film.
