01. Touch: Feel for Protrusions at Edges          Smooth to the Touch

Gently touch the label edge with your fingers:
         • In-Mold Labeling: Completely no "step feeling"—the label and container surface are seamlessly integrated, and you may even be unable to feel the existence of the label.
         • Traditional Labeling: You can clearly feel the connecting gap between the label and the container, and some may also have a slight protrusion feeling.

02. Scratch: Test If the Label Peels Easily          Firm & Scratch-Resistant

Gently scratch the label surface with a fingernail or key:
         • In-Mold Labeling: The pattern will not fade, and label edges will never peel or flake—extremely strong protection.
         • Traditional Labeling: If the scratching force is slightly greater, pattern surface peeling or label curling and damage can easily occur.
