Heat shrink tunnels
Heat shrink tunnels are used to shrink film or sleeves around products and containers. The tunnel must match film type, pack size, conveyor speed and heat tolerance of the product.
How to specify heat shrink tunnels.
Use these points to prepare a stronger machinery enquiry and narrow the equipment range before quotation.
Best-fit applications
Heat shrink tunnels are most useful when the machine format is matched to the product, pack and operator process rather than chosen from headline speed alone.
- tamper bands, sleeve labels and shrink film packs
- bottles, jars, tubs, cartons and bundles
- integration after sleeve application or wrapping
Details to confirm before selection
Accurate specification starts with samples, real production targets and a clear view of what happens before and after this process.
- film or sleeve material and required shrink percentage
- pack dimensions, heat sensitivity and conveyor speed
- tunnel aperture, heat zones, airflow and dwell time
Build a practical enquiry
Send product details, filled and empty pack samples, photos or videos of the current process, expected output and any site restrictions. This helps identify whether a standard machine, tooling change or integrated line is the correct route.
- Include product and pack photos where possible.
- State current output, target output and operator involvement.
- Confirm whether the requirement is standalone equipment or line integration.
Heat shrink tunnels FAQs
What affects shrink quality?
Film material, heat, airflow, dwell time and pack consistency all influence the finish.
Can heat damage products?
Yes, heat-sensitive contents or containers must be reviewed before selecting a tunnel.
Where does the tunnel fit?
Usually after a sleeve applicator, L-sealer or wrapping stage.
