Automatic Steam Heat Shrink Tunnel Machine Manufacturer & Supplier In Great Britain

In sleeve labeling applications where premium appearance, uniform finish, and distortion-free shrinking are essential, steam-based shrinking technology is widely preferred over dry heat methods. An Automatic Steam Heat Shrink Tunnel Machine delivers controlled, gentle, and consistent shrinking of sleeve labels, ensuring flawless adhesion even on complex container shapes.

Manufacturers operating across Great Britain, including beverage and cosmetic packaging units in London’s outer industrial zones, Bristol, Milton Keynes, the Midlands manufacturing belt, and Northern England, increasingly rely on steam heat shrink tunnels to meet high visual and quality expectations. The Automatic Steam Heat Shrink Tunnel Machine manufactured by Technogen Enterprise is engineered to support these requirements with precision, reliability, and process flexibility.

What Is an Automatic Steam Heat Shrink Tunnel Machine?

An Automatic Steam Heat Shrink Tunnel Machine is a sleeve shrinking system that uses superheated steam to shrink sleeve labels uniformly around containers. Unlike electric or hot-air tunnels, steam tunnels provide controlled moisture-based heat transfer, which allows the sleeve to conform smoothly to the container without burning, melting, or uneven shrink lines.

This machine is suitable for shrinking sleeve labels and neck bands made from PVC, PETG, OPS, and PLA materials and is widely used where high-end packaging aesthetics are critical.

Working Principle of the Automatic Steam Heat Shrink Tunnel Machine

The machine operates through a carefully controlled sequence to ensure consistent sleeve shrink quality:

1. Entry of Sleeved Containers

Containers with pre-applied sleeve labels enter the tunnel on a variable-speed modular Delrin slat chain conveyor. Conveyor speed is adjusted to match production requirements.

2. Steam Generation

Steam is generated using an external or integrated steam source. The steam is delivered at controlled temperature and pressure suitable for sleeve shrinking.

3. Multi-Zone Steam Application

The tunnel is designed with multiple steam zones, which can be set independently. Each zone directs steam precisely to the required area of the container.

4. Adjustable Steam Manifold

Steam flow is distributed through a modular steam manifold, which can be adjusted according to bottle size, shape, and sleeve material.

5. Uniform Shrinking Process

Superheated steam surrounds the container evenly, shrinking the sleeve from all sides without melting or damaging the film.

6. Steam Exhaust and Moisture Control

An air blower with an adjustable exhaust window removes excess steam, while an integrated drip tray collects condensed moisture.

7. Discharge

After shrinking, containers exit the tunnel with uniformly shrunk sleeves and a premium finish, ready for downstream packaging operations.
