Shrink Tunnel
Standalone recirculating hot-air tunnel.
Built around your product
Pair it with any sealer or sleeve applicator. Insulated double walls, directed airflow and a roller or mesh conveyor give even shrink with low energy use.
The product is enveloped in centre-folded or flat film and the open edges are sealed by a hot knife or impulse wire. In the tunnel, recirculated hot air shrinks the film evenly around the product. Polyolefin is used for retail display packs; polyethylene for heavier transit bundles.
Key features
- Adjustable airflow direction
- Live roller or mesh belt
- Cool-down fan at exit
- Digital temperature control
Process sequence
