    • 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.
    • 用于生产标签承载制品(10)的方法要求将标签(16)粘附到薄热塑性基材(12)的外表面(14)上,并将热塑性基材(12)和固定标签 (16)进入注射成型设备的模腔中,其中标签轴承外表面(14)抵靠模腔的壁。 熔融的热塑性树脂在压力下被注入到模腔中,使得树脂与热塑性基材(12)的内表面(15)接触,从而牢固地挤压热塑性基材(12)的外表面(14) 标签(16)抵靠模腔的壁,从而形成复合制品(10)。 在模具腔内设置足够的热量和压力,以将标签(16)至少部分地凹入到热塑性基材(12)的外表面(14)中,并将热塑性基材(12)整体模制到标签(16)上。 然后将复合制品(10)从模具腔中冷却并移除。
