Shrink Tunnels feature extra length when compared to our standard heavy duty tunnels and are perfect for packing, sealing, and shrink wrapping larger size products. The extra length can also accommodate longer shrink time at a faster pace or film that requires a lower shrink temperature. Due to their precise temperature and speed controls, extra length tunnels are perfect for shrinking a wide range of films, from the lightest polyolefin to the toughest polyethylene films.
