Footwear Tongue Label Challenges

Manufacturers producing tongue labels for sports, casual, or premium footwear often encounter:

  • High-temperature damage: Heat during bonding can burn, harden, or discolor delicate uppers such as mesh or Flyknit.

  • Poor printing results: Conventional materials cause logos and size markings to fade, peel, or blur after repeated washing and bending.

  • Production inefficiency: Long hot-pressing cycles and inconsistent adhesion increase defects.

  • Durability issues: Labels fail under bending, sweat exposure, or wash cycles, impacting brand image.

  • Customization limitations: Traditional materials offer limited flexibility in thickness, color, or surface finish.

GREEN TPU Dual-Layer Solution

We offer a dual-layer structure optimized for tongue labels, combining a low-temperature hot-melt adhesive base and a high-temperature printable TPU top layer.
