Shrink Tunnels
4 videos • 0 views • by INPAK SYSTEMS A shrink tunnel or heat tunnel is a heated tunnel mounted over or around a conveyor system. Items (such as bottles or containers) have shrink film loosely applied and with heat, the film shrinks to fit snugly around the product. Typical uses are: applying labels, tamper resistant bands and a barrier on foods. The heat source can be a heating element, infrared heater, steam, or gas flame. Often forced air is used to improve convection.
