Arpac Brand MPD Model Shrink Tunnel

Our MPD Model tunnel range is a bottom air flow shrink tunnel with a mesh belt conveyor designed to produce complete, uniform shrink using all available shrink films – including polyethylene, polyolefin and PVC.

The MPD model range has heavy duty, variable speed blowers creating a high velocity, recirculating air system which forces hot air throughout the tunnel. The teflon coated mesh, fiberglass conveyor allow this hot air to reach all surfaces of the package, resulting in a uniform shrink on a wide range of product sizes and configurations. Control systems regulating temperature, air velocity and conveyor speeds, allow for a variety of operating conditions and ensure optimum shrink on all heat shrinkable packaging films.
