The present invention provides a process for manufacturing an embossed shrink film having one or more embossed devices such as optical devices, optical lenses, holographic images, holographic textures, static images, textured patterns, and graphical text. An embossing tool is provided having a raised image corresponding to the embossed device and a film is embossed by extruding the film across the embossing tool to form the embossed devices in the film. The embossed film is tentered, proportionally stretching the embossed devices along with the film. The tentered film is stored for subsequent forming into a sleeve of film that can be placed about a product and shrunk by heating to form a contoured shrink film on the product, the film retaining the embossed devices in proportion to the shrinkage of the film.
