Shrink Tunnel Systems & Heat Methods
While sealers handle the film cutting and sealing process, shrink tunnels are where the final packaging quality is truly determined. These systems apply controlled heat to shrink the film evenly around each product, creating a tight, professional finish.
For industrial operations, the tunnel’s design, airflow, and temperature precision directly impact productivity, material efficiency, and package integrity.
How Shrink Tunnels Work
After the product is sealed, it enters a heated tunnel via conveyor. Inside, circulating air or radiant heat causes the shrink film (PVC, POF, or LDPE) to contract uniformly. The package then cools upon exit, locking the film in place for a clean, tamper-evident appearance.
Types of Shrink Tunnels
Each type can be configured for inline or standalone use depending on production layout and product type.
Integration Best Practices
- Align tunnel speed with sealer output. Mismatched rates can cause film sagging or burn-through.
- Maintain regular tunnel cleaning to prevent buildup that can disrupt airflow.
- Calibrate heat sensors periodically for consistent performance.
- For large packaging lines, dual-tunnel setups (preheat + finish) maximize shrink quality without overheating products.
John Maye Company supplies a range of SMIPACK and Heat Seal sealing systems.
- SMIPACK T Series Tunnels: Compact, high-efficiency tunnels with adjustable airflow control and reduced power draw.
