Steam Shrink Tunnels for Sleeve Labels and Shaped Containers
Steam tunnels are often considered for shaped containers and full-body shrink sleeves because controlled heat distribution can help the sleeve shrink around curves and shoulders.

Best-fit applications
Where this sleeve applicator route usually fits.
The tunnel should be specified at the same time as the sleeve applicator. A good steam tunnel route considers utilities, ventilation, line speed, shrink quality, container shape and operator access.
- Full-body sleeve labels on curved or shaped bottles
- Applications where appearance is critical around shoulders
- Production sites with suitable steam supply or generator options
- Sleeve materials that respond well to controlled steam shrink
- Steam availability and condensate management
- Container material and product temperature sensitivity
- Sleeve material and shrink curve
- Tunnel length, dwell time and line speed
- Moisture management around coding and downstream packing
Specification checks
Details to confirm before choosing the machine.
Good sleeve applicator selection starts with the real pack, the real sleeve and the target output. The checks below help narrow the applicator, conveyor and tunnel route before a quotation is prepared.

Steam tunnels questions
Is steam always better for sleeve labels?
No. Steam can be excellent for some shaped packs, but electric or hot-air tunnels may be better for other products and site conditions.
Does a steam tunnel need a steam generator?
It depends on site utilities. Some projects use existing steam and others require a generator or alternative tunnel route.
Can steam affect bottles or caps?
It can if the pack is sensitive. Samples should be checked for distortion, condensation and finished-pack appearance.
