How to Choose the Ideal Shrink Tunnel for Your Production Line

The shrink tunnel is one of the main components in packaging lines that use shrink sleeve labels. It applies controlled heat so the shrink film molds perfectly to the container’s shape. For industries seeking speed, standardization, and high performance, this equipment has become essential.

When choosing the ideal shrink tunnel, it is necessary to consider not only compatibility with the production line, but also technical features and the manufacturer’s reliability. Companies such as IMEK stand out by offering complete solutions with national technology and specialized technical support.

How the shrink tunnel works

The process is based on applying heat — through electric resistances or infrared — on a shrink film previously placed around the product. The heat makes the film contract and adjust precisely to the container’s surface, ensuring a uniform and attractive finish.

In practice:

• The package is placed on a conveyor belt that passes through the tunnel.

• Internal fans and resistances heat the chamber, activating sleeve shrinking.

• IMEK models allow digital control of temperature, ventilation, and conveyor speed for fine adjustments according to each product.
  
  

IMEK also offers 304 stainless steel structures, removable trays for easy maintenance, and control panels with intuitive HMI. This robust design ensures durability and continuous efficiency.

How to choose the best shrink tunnel

Key factors to evaluate:

1. Product type and container shape (cylindrical, oval, complex).

2. Production volume (continuous or batch processing).

3. Available space in the plant.

4. Sleeve type used (PVC, PET, OPS).

5. Control features: digital temperature, airflow, and speed adjustment.

6. Ease of maintenance (removable trays).

7. Technical support and after-sales reliability.

Industrial applications

Shrink tunnels are widely used in:

• Food and beverage industry.

• Cosmetics and personal care products.

• Pharmaceuticals and supplements.

• Cleaning products and sanitizers.

• Toys and household items.
  
  

Ideal for any application demanding professional finishing and full adhesion of the label to the container.

Choosing the right shrink tunnel is a strategic step for companies seeking efficiency, product appeal, and waste reduction.
