Steam Heat Tunnels for Perfect Shrinking Printed Shrink Sleeves

Tripack ST series steam tunnels perfectly handle a wide range of applications for shrink sleeve labels and tamper evident bands.

Tripack offers three different sized ST steam tunnels that can be used independently or combined in line to achieve the best shrink performance for your products. All three steam tunnels are fabricated out of heavy-gauge stainless steel and have dual-wall construction.

Tripack's ST steam shrink tunnels vary by adjustable opening, overall tunnel length, and number of heating zones. Shrinking of film is a function of time and temperature.

There is a correlation between tunnel length and conveyor speed based on product size and throughput. The ST-3 is Tripack's smallest steam tunnel and has a single zone. The ST-1 and ST-2 models have multiple zones that can be set up independently. To achieve optimal shrink for a great looking product, correlate product size and throughput requirements with tunnel length, and utilize either a single tunnel or multiple tunnels.

Tripack steam tunnels have six adjustable baffles per zone, three per side. Each baffle can be adjusted up/ down, in/out, and yaw pitch for directing steam directly where it is needed on your product. Each baffle has its own flow control ball valve with calibration scale to throttle back the steam in a particular area, if needed.
