A Steam Shrink Tunnel is a specialized packaging machine designed to apply heat to shrinkable sleeve labels (such as PVC, PET, OPS, or PLA) using steam as the heating medium. Unlike electric or infrared shrink tunnels that use dry heat, steam tunnels utilize saturated steam to provide uniform, gentle heat distribution, ensuring that sleeve labels shrink tightly and evenly around containers without damaging the product or label graphics.
Steam shrink tunnels are widely used in the beverage, food, dairy, pharmaceutical, and personal care industries for full-body sleeve labeling, tamper-evident bands, and promotional sleeve applications.
