Sleeve Shrink Tunnel

Compare Shrink sleeve heat tunnels that are used to shrink the sleeves over tall containers placed on a production line conveyor or shrink the security sleeve bands.. Consequently, the tunnel itself is in the form of an upside down U. This shape leads to distinctly different dimension characteristics than the more traditional type of heat shrink tunnel described.

The Tunnel Inside Dimensions of width and height are more narrow and higher respectively. Longer length is usually achieved by a tandem configuration of more than one tunnel.

Heating methods employed also differ. Radiant infrared, steam, and convective electric heat are parameters defining the methods. The heat method chosen is driven by the target type of sleeve; either label, band, or both. The temperature has to be sufficiently high for effective shrinking, but not so high to adversely affect the container or the products in those instances where the product is packed first and then is labeled. In the case of security bands, the product is always packed already.
