FILM HAVING OPTICALLY VARIABLE EFFECT STRUCTURE

摘要

A shrinkable film element is provided which consists of a shrinkable film with an optically variable effect on the external surface of the film and imaged regions and/or indicia on the internal surface of the film. The film in the form of a shrink wrap sleeve provides for a stable better quality image after heat shrinking onto an object. The images and indicia may be easily observed and are stable and the optically variable effect is less susceptible to post heat shrinking degradation and loss of image quality.
