Steam Tunnel

Steam Tunnel Machine

The Steam Tunnel is a high-performance shrink tunnel used for uniform shrinking of shrink sleeves on bottles, jars, and containers using controlled steam. Manufactured by Magic SPM, this tunnel delivers superior shrink quality, making it ideal for complex container shapes and high-end sleeve labeling applications.

Steam shrink tunnels are widely used in beverage, food, pharmaceutical, FMCG, and cosmetic industries where precise sleeve conformity and professional finish are critical. The system integrates seamlessly with auto shrink sleeve applicators to form a complete shrink sleeve labeling line.

Machine Overview

The Steam Tunnel works by exposing containers with applied shrink sleeves to controlled steam inside a tunnel chamber. The steam causes the sleeve to shrink evenly around the container, ensuring tight fitting without wrinkles or distortion.

Steam-based shrinking is especially effective for contoured and non-uniform containers, providing excellent sleeve finish and consistent results even at high production speeds.

Applications

The Steam Tunnel is commonly used in:

  • Beverage bottling plants

  • Food packaging units

  • Pharmaceutical packaging lines

  • FMCG production facilities

  • Cosmetics and personal care packaging

  • Chemical and industrial product packaging
