Airflow: The air in a recirculating shrink tunnel is recycled or recirculated within the tunnel. It heats the air, and the air is reused for shrinking the film. This system is more energy-efficient.
Film Shrinking: Provides a more controlled shrinkage ,particularly those that are more heat-sensitive.
Energy Efficiency: More energy-efficient since the air is recycled within the system, making it suitable for longer production runs.
