METHOD OF MANUFACTURING A HIGH DOI/HIGH GLOSS MULTIFUNCTIONAL THERMOPLASTIC FILM

摘要

A method of making a high gloss, multilayered thermoplastic film by pinning the extruding the molten thermoplastic film material onto a polished casting roll having a mirror finish. The thermoplastic film produced by this method has a superior gloss finish and has a ratio of distinctness of image in the machine direction to distinctness of image in the cross direction in the range of 1.3:1 to 1.0:1, and has a 20° gloss in the machine direction and the cross direction of at least 40.
