Abstract
A process for producing a label bearing article (10) calls for an adhesive mounting of a label (16) to an exterior surface (14) of a thin thermoplastic substrate (12), and placing the thermoplastic substrate (12) and the affixed label (16) into a mold cavity of an injection molding apparatus with the label bearing exterior surface (14) against a wall of the mold cavity. A molten thermoplastic resin is injected into the mold cavity under pressure so that the resin contacts an interior surface (15) of the thermoplastic substrate (12) to thereby firmly press the exterior surface (14) of the thermoplastic substrate (12) and the affixed label (16) against the wall of the mold cavity, thereby forming the composite article (10). Sufficient heat and pressure are provided within the mold cavity to at least partially recess the label (16) into the exterior surface (14) of the thermoplastic substrate (12) and integrally mold the thermoplastic substrate (12) to the label (16). The composite article (10) is then cooled and removed from the mold cavity.
