A plastic barrier screen that is molded and drawn the screen is formed from a process that uses the speed of injection molding to form a part that can be mechanically oriented in a second operation that is equally fast. The plastic barrier screen is first formed from injection molding a part with multiple square or hexagonal holes ½ to &frac16 opening size in a uniform pattern, including longitudinal dividers between such holes of 2 to 6 times the final desired screen barrier cross sectional area of the longitudinals respectively. The molded part is then stretched along the longitudinal elements of the mold to molecularly orient at elevated temperature to produce a larger planar dimension of 2 to 6 times the original plastic screen with high strength molecularly oriented monofilament longitudinal elements.
