Abstract: Inherently low orientation sheet is produced by extruding a thermoplastic material in its melt phase onto the surface of a chill roller and thereafter solidifying the sheet at a relatively slow chill rate. Importantly, the just extruded thermoplastic polymeric sheet (i.e., the melt) is urged into continuous surface-to-surface contact with the chill roll by a curtain of air impinging upon the sheet at a velocity sufficient to ensure such continuous surface-to-surface contact between the sheet and the chill roll, but insufficient to impart substantial stress to the sheet. In such a manner, therefore, the resulting sheet will exhibit a low inherent internal stress level as evidenced by an unusually low shrink rate (ASTM D-1204) of less than about 18%.
