Shrink Tunnels

A shrink tunnel (also commonly known as a heat tunnel) is a metal tunnel that sits above or is built around a conveyor, often being fed from a heat-sealing machine.

The tunnel has a heating element that heats the film as they move through the machine. Your products are conveyed through the tunnel and are cloaked with loosely fitting shrink film.

When your products move past the heating elements, the film shrinks uniformly around the items as they are exposed to the heat.

Our available machines can be combined with sealing machinery and are perfect for shrinking a wide range of films, from the lightest polyolefin to the toughest polyethylene films.
