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

摘要

A method of making a high gloss multilayered polyolefin film (12), characterized by the absence of polyvinyl chloride, by coextruding the layers onto a polished casting roll (112) having a mirror finish. The multilayered polyolefin film (12) produced by this method has a high gloss finish and a distinctness of image in the cross direction in the range of 1.3:1 to 1.0:1, and has a 20 degree gloss in the machine direction and the cross direction of at least 40.
