        Film production test line

        We provide optimal systems to our customers, using our rich experiences in designing and producing film production lines, and using film production test lines.

        Film production test line

        Feel free to contact us about R&D of new materials, or before implementing production and test facilities.

        Line composition

        • Twin screw extruder (with gear pump attached)
        • Socket
        • Casting Machine
        • Longitudinal Stretching Machine
        • Mill Roll Winding Machine
        • Biaxial stretching machine (offline)


        • Compact line composition
          The amount of raw materials used during testing is kept low so as to reduce the burden on our customers
        • Able to handle high-temperature extrusion (max. 400°C)
          Can be used for extruding and forming heat-resistant film, etc.
        • Various stretching patterns (longitudinal stretching machine)
          Able to study the most appropriate stretching conditions by changing the roll’s position.
        • Easily obtain samples within the process
          Able to obtain samples from within the process, something which is difficult in production machines
        • Stretch testing using biaxial stretching machine (offline)
          Able to conduct sheet by sheet single-axis and biaxial stretch testing (simultaneous, sequential).
