Shrink Wrapping Made Simple: An Introduction to Steam Shrink Tunnels

Steam shrink tunnels are an efficient and effective way to shrink wrap products and packages. In a steam shrink tunnel, products pass through a chamber filled with heated steam, causing the shrink wrap film surrounding them to shrink down tightly. This provides a tight, wrinkle-free covering that protects items during shipping and storage.

Some key benefits of using steam shrink tunnels include:

  • High-speed processing - Steam tunnels can wrap up to 100+ items per minute, allowing for fast inline processing.
  • Quality wrapping - The steam causes the film to shrink smoothly and evenly for a tight, professional look.
  • Versatility - Steam tunnels can be used to shrink wrap a wide variety of products of different shapes and sizes.
  • Cost-effectiveness - Steam shrinking uses less floor space and energy compared to other shrink methods.
  • Safety - Steam tunnels enclose the shrinking process, protecting workers and products.

The shrink wrapping process starts by guiding products through the tunnel on a conveyor belt. Inside the heated tunnel, precision nozzles release steam to surround the items. The heat from the steam causes the shrink wrap film to shrink and conform to the shape of the product. Usually, the plastic will shrink to around 20-30% of its original size.

Once through the tunnel, the wrapped items are quickly cooled and dried. This sets the shrink wrap into its final tightened form. Conveyors then transport the finished products out of the tunnel for inspection, packaging or shipping. Heat shrink tunnels often include automatic sensors and controls to ensure optimal settings and tunnel conditions for each product.

With their speed, quality output and efficient operation, steam shrink tunnels have become a staple of industrial packaging. They allow companies to swiftly and securely wrap everything from food packages to industrial toolboxes. For businesses looking to ramp up their shrink wrapping productivity, steam tunnels provide an accessible and reliable option.
