    • A label construction comprises a temporary carrier web having a release surface and a label releasably adhered to the release surface. The label comprises a radiation cured face film in contact with the release surface of the carrier web and a layer of pressure sensitive adhesive on the side of the label opposite the carrier web, and may comprise indicia between the face film and the layer of adhesive. A protective backing covers the adhesive and has a second release surface in contact with the adhesive. Adhesion between the release surface of the protective backing and the layer of adhesive is weaker than adhesion between the release surface of the temporary carrier backing and the face film. The protective web can be removed from the label to expose the adhesive while leaving the label releasably adhered to the carrier web. The exposed adhesive is applied to a substrate and the temporary carrier web is removed, leaving the label adhered to the substrate.
    • 标签结构包括具有释放表面和可释放地粘附到释放表面的标签的临时载体网。 标签包括与载体网的释放表面接触的辐射固化的表面膜和与载体网相对的标签侧上的压敏粘合剂层,并且可以包括在面膜和粘合剂层之间的标记。 保护衬垫覆盖粘合剂并且具有与粘合剂接触的第二释放表面。 保护背衬的释放表面和粘合剂层之间的粘合力弱于临时载体背衬的释放表面和面膜之间的粘合。 可以从标签上取下保护片,露出粘合剂,同时使标签可剥离地粘附在载体网上。 将暴露的粘合剂施加到基底上,并移除临时载体网,使标签粘附到基底上。
