The planar elongation flow is one of the important flow field to form thin film and PET bottle formation process. The flow field of a steady planar elongation with high elongation rate was generated by using the flow focusing technique with sheath flow. In order to generate the higher elongation rate, a new device which combines a flow driving piston with a test section were developed and the ability was confirmed. In addition, the planar elongation stress was evaluated by using the channel that was 180 turns while a regular expansion was flowing.
