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

Sleeve labeling has become a dominant packaging method for modern consumer products due to its ability to deliver full-body branding, tamper evidence, and a premium shelf appearance. However, the final visual quality of a sleeve-labeled container depends heavily on the shrinking process. An Automatic Electric Heat Shrink Tunnel Machine ensures that sleeve labels shrink uniformly, adhere perfectly to container contours, and maintain a wrinkle-free finish.

Manufacturers operating across Great Britain, particularly in Birmingham, Coventry, Leicester, Manchester, Leeds, and Milton Keynes, rely on electric heat shrink tunnel technology for consistent labeling in beverage, pharmaceutical, cosmetic, and chemical packaging lines. The Automatic Electric Heat Shrink Tunnel Machine engineered by Technogen Enterprise is designed to meet these operational demands while maintaining reliability, safety, and process control.

What Is an Automatic Electric Heat Shrink Tunnel Machine?

An Automatic Electric Heat Shrink Tunnel Machine is a packaging system used to shrink sleeve labels onto containers using electrically generated hot air. It is specifically designed for round plastic bottles and works with sleeve labels made from PVC, PP, PETG, and OPS films.

The machine uses a forced convection heating principle, where heated air is circulated uniformly inside the tunnel to ensure even shrinking of the sleeve label across the entire container surface. Sleeve placement on the container is manual, while the shrinking process itself is fully automatic, making the system suitable for medium to high-speed production environments.

Working Principle of the Automatic Electric Heat Shrink Tunnel Machine

The machine operates through a controlled and repeatable process designed to ensure consistent sleeve shrink quality:

1. Manual Sleeve Placement

Operators manually place the sleeve label over the body of the round plastic container. Proper positioning at this stage ensures accurate shrinking later in the process.

2. Container Feeding

Once sleeved, the containers are placed onto the AISI 304 slat conveyor, which is designed for smooth, stable container movement.

3. Conveyor Speed Adjustment

The conveyor speed can be adjusted through the operating panel’s speed control port. This allows synchronization with upstream sleeve applicators and downstream packaging equipment.

4. Tunnel Entry

Containers enter the heat shrink tunnel in a controlled sequence, maintaining adequate spacing for uniform heat exposure.

5. Forced Convection Heating

Inside the tunnel:

• Pin heaters heat the air to a superheated level

• Two blower assemblies circulate the hot air evenly
  This forced convection method ensures that heated air surrounds the container uniformly from all sides.

6. Sleeve Shrinking

As the container travels through the tunnel, the sleeve label shrinks tightly and evenly around the bottle body, adhering perfectly to its contours.

7. Exit and Discharge

After shrinking, containers exit the tunnel with properly shrunk and securely fitted sleeve labels, ready for downstream inspection or packing.
