■ Co-OI
    (Take-up unit oscillating type)

The take-up unit turns around to produce high quality film of a better finished roll shape.

■ Co-RI
    (Take-up unit and winder rotating type)

The take-up unit and winder rotate simultaneously to completely shut out environmental effects such as surrounding temperature, and produce high quality film of no imperfections.

■ Co-RT
    (Extruder rotating type)

This type offers the merit that ambient temperature inconsistencies caused by the extruder are dispersed by rotating the extruder. And, the take-up unit is of a simple configuration that readily lends itself to line expansion.

■ Co-RD
    (Die rotating type)

The rotating die helps to reduce costs and enhance easeā€“of-use.

■ Co-MP
    (General purpose type)

This general-purpose line is space-saving, low cost and easy to operate and maintain.

■ Co-DI
    (Downward type)

This forming line is designed for downward delivery best-suited for low melt viscosity resins like PP, PA, EVOH, etc.
