Products Detail


Steam Shrink Tunnel model SZ SST380 comes with Air Drier integration. By blowing compressed air onto containers coming out from steam heating process, this device is capable of reducing water drop on containers and make immediate carton loading possible.

Pre and post shrink station is available on this bottle label steam shrink tunnel. They are equipped to heat up the specific positions of sleeve labels, e.g. container bottom or neck, to prevent from movement due to sudden temperature change. Many users find the shrink sleeve tunnel machine very helpful on tall and glass containers.

Steam Shrink Tunnel model SZ SST380 is ideal for either stand alone or production line integration.

Q.    People sometimes use the terms "Shrink Tunnel" and "Steam Shrink Tunnel" interchangeably. What's the difference?

A.    Steam Shrink Tunnels are one of the 3 major types of Shrink Tunnels. The others are Hot Air Convection Tunnel and Radiant Infrared Tunnel.

Q.    What are some factors to consider in choosing one vs. the other?

A.    For tamper evident applications, a Hot Air Convection Tunnel produces exceptional results. When neckbands are very dark in color, Radiant Infrared Tunnel is the optimum choice. Steam Shrink Tunnel is the best option among the Shrink Tunnels for full body labels. 

Q.    Which is the better choice when graphics and registration are critical?

A.    Steam Shrink Tunnels are best for products where high quality, distortion-free graphics are most important. Because Steam Shrink Tunnels provide more uniform heat impingement than air systems. In addition, Steam Shrink Tunnels provide more precise label registration and shape conformance.  

Q.    What type of Shrink Tunnels are recommended for applications involving volatile products?

A.    Steam Shrink Tunnels are the best choice for containers that are under pressure, or when a low flash point or flammability is a factor.

Q.    Are aerosols compatible with Shrink Tunnels for packaging?

A.    Yes, Steam Shrink Tunnels are an excellent alternative for aerosol containers and other packaging programs where low flash point or flammability is a factor. 

Q.    What sleeve labels can be used for processing in shrink tunnels?

A.    There are several main types, and new varieties of each type being developed all the time. PVC is the most common and least costly. It’s also easiest to control during the shrink. PETG has the highest shrink percentage. They are recyclable and very versatile, and can be ordered with special attributes such as a matte finish or velvety texture. OPS has the lowest vertical shrink and produces the most consistent results, particularly on squeeze bottles. PLA is a plant-based alternative to petroleum-based shrink films. They are strong and dimensionally stable, and their high water transmission rate prevents moisture from being trapped between the container and the sleeve label when containers are steam shrinked. 

Q.    What is the value of adding a pre or post-shrink module to shrink tunnels?

A.    These modules finish off critical areas at the base or top of the sleeve in the most energy-efficient manner. They are self-contained industrial heat guns, sometimes used in pairs, and often with nozzles to focus the heat. Power usually comes through the application equipment. Hot Air or steam flow is paused while the machine waits for product, and only turned on when product is present. 

Q.    How can we reduce the risks involved with changing from printed self-adhesive labels to full-body sleeves cured in Shrink Tunnels?

A.    It's critical to understand every factor that can impact your end result. Our technicians work with you to fully understand your package concept and identify the best possible materials and Shrink Tunnels configuration to achieve best-possible results.

        Send your containers and sleeve labels to test our Shrink Tunnel, before placing your order. We will provide video & photos for so that you see the way our Shrink Tunnel works on your samples and how good the shrink results on your samples are.
