Shrink Tunnels (Machines)
Shrink Tunnels (Machines)
Shrink tunnel systems provide precise, consistent heat application for shrink sleeve label finishing across high-volume production operations. These engineered systems deliver controlled temperature, airflow, and dwell time to achieve uniform sleeve shrinkage without container distortion or label defects. Advanced tunnel designs accommodate diverse container materials, sizes, and production speeds from pilot operations to industrial-scale manufacturing.
Our shrink tunnel portfolio encompasses steam tunnels for rapid, gentle shrinkage ideal for thin-walled PET bottles, and hot air tunnels for versatile applications across container types. Modular designs enable capacity scaling and quick format changes for multi-product operations. Integrated conveyor systems ensure smooth product flow with adjustable speed matching to upstream sleeving equipment and downstream filling or packaging lines.
Modern tunnel systems feature energy-efficient heating, precise temperature profiling across multiple zones, and automatic parameter adjustment based on container size and material. Safety interlocks protect operators while maintaining production efficiency. The tunnels integrate seamlessly with automated sleeving equipment, creating complete turnkey shrink labeling systems from sleeve application through finished product inspection.
