Heat tunnels

Controlled shrink finish for L-sealers, sleeve sealers and shrink wrapping lines.

Product option

Heat Tunnels

The heat tunnel is responsible for the final pack appearance. It must be matched to the film, pack size, conveyor speed, airflow, temperature setting and the upstream sealing equipment. Correct tunnel selection helps avoid loose film, burn-through, distorted packs and inconsistent presentation.

  • Specified around film type, pack size and desired shrink finish.
  • Works downstream of L-sealers and sleeve sealers.
  • Tunnel length, chamber size and conveyor speed should match output.
  • Useful for improving presentation quality and consistency.

Why it matters

How this route is usually selected

Finish control

Temperature, airflow and dwell time are balanced for the required shrink result.

Integration point

Tunnel size and conveyor height need to suit the upstream sealing machine.

Quality improvement

Correct tunnel selection improves pack consistency and reduces rework.
