Method for enhancing the three-dimensional effect of a raised plastic surface using in-mold labeling

The present invention relates to a method for enhancing the visual effect of a three-dimensional molded part using in-mold labeling and the label used therewith, particularly a method and label for enhancing the three-dimensional visual effect of raised surfaces on a blow molded article. A method of enhancing the three-dimensional effect of a plastic part and the label used therewith is disclosed. A label for enhancing the three-dimensional visual effect which comprises a plastic core and/or, an insulating layer, and/or a heat-activated adhesive backing is disclosed. The label is aligned on the surface of a relieved mold. When plastic is forced against the back surface of the label, the label is stretched and forced into the relief along with the plastic. The label adheres to the plastic part by either a heat-activated adhesive backing or the core forms a melts/weld interface with the molded part creating a permanent bond between the label and the molded part.
