  • METHOD FOR PRODUCING ULTRAHIGH MOLECULAR WEIGHT POLYETHYLENE FILM
    Publication number: 20110319585
    Abstract: Disclosed is a method for producing a ultra high molecular weight polyethylene film, which comprises: a step of forming a film using a ultra high molecular weight polyethylene material; a step of biaxially drawing the film obtained in the step in the x-axis direction and in the y-axis direction at a temperature not less than the melting point of the ultra high molecular weight polyethylene material; and the step of shrinking the film along at least one of the x-axis direction and y-axis direction. By this method, a ultra high molecular weight polyethylene film having high tensile strength at break, high tear strength and excellent uniformity can be efficiently produced at low cost.
