Abstract
Abstract An overwrapping film wherein a plastic base film is coated with a plastic material to form an anchor coat layer, which is, in turn, further coated with ink to form an ink layer thereon, and a metal layer is then deposited on the ink layer through the process of vacuum evaporation. The plastic base film is thermally contracted to produce a tightly-packed configuration, while the evaporated metal layer furnishes a metallic gloss to a printed display pattern provided by the ink layer.
