Machine Direction Orientation (MDO), has been practiced, with varying success, for decades. The dramatic improvements in film clarity, stiffness, barrier, and tensile strength has been documented since the 1950’s. In the past few years’ companies have begun to commercialize this technology in an ever-increasing rate. Until recently, with a few exceptions, the machine used to MDO the film has changed very little. In this paper, a short overview will be presented discussing some of the important facets of the MDO machine, and how they affect the orientation process, and ultimately, the final film properties.
