Products Detail


Steam Shrink Tunnel model SZ SST100 is an entry level model suitable for regular shape containers and uniform size application, such as bottle water, dairy and milk products. A stand-alone or built-in Steam Generator is available at extra cost to supply high temperature steam to this machine. In some cases, SZ SST100 cooperates with Automatic Sleeve Applicator applying sleeve labels onto containers up to 120 bottles per minute. Contact us for this application.

The single section chamber on SZ SST100 focuses the application of heat, minimizes energy use, optimizes container appearance and minimizes the risk of container distortion. Each Pipe Line installed is adjustable to fit container diameter and height. Side doors on chamber provide easy access to Pipe Line adjustment.

SZ SST100 is whole 304 stainless steel construction. The stainless steel shrink tunnel with water-proof design and water collecting plate to collect the condensate water. A ventilator installed on top of chamber removes excess steam out of and keep workplace clean and dry.

We offer customized model in accordance with user's specific demand. OEM and ODM orders are acceptable.

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.
