Lamb Weston ® retrofits Ceetak Quick Pulse Heat Sealing technology across packaging production line in Wisbech factory Lamb Weston is a world leading brand controller. This is held for the required in high quality potato products, and is duration and then removed. sold in over 100 countries around the world. Supplying frozen potato products The second stage is the cooling phase to customers in the Food Service, Quick of the process. The temperature of the Service, Industry and Retail market patterned sealed area (again monitored segments. The company operates six by the temperature controller) is cooled factories in; The Netherlands, Russia, rapidly by a stream of water through United Kingdom and Austria. the sealing bar provided by the thermal regulator unit of the system. The rapid Due to great success with other frozen heating and cooling process takes only food manufacturers, Ceetak approached milliseconds and this facilitates fast Lamb Weston with their Quick Pulse cycling times and increases output. Heat (QPH) sealing technology; a cyclic system which can be used on all By reducing the temperature of the thermoplastic films, and incorporates sealed area, the system ensures that the a unique seal bar and anvil design to weld is not weakened during handling (as create a narrow width, patterned seal is possible if left to cool naturally). This for material savings with superior seal is typically 1-1.5mm wide, showing performance characteristics. a film material saving of approximately 10% against traditional crimp seals on the The first stage of the QPH sealing system cross seal alone. The QPH sealing system is the cut and seal phase. The jaws close ensures that heat and pressure are on the film and the desired temperature applied evenly across the sealing surface of the heated bar is reached and creating a completely fused, hermetic maintained by a designated temperature seal. 66 FDPP - www.fdpp.co.uk Ceetak provided Lamb Weston with a free on site survey and installed a free trial of the QPH seal technology; it was installed on one packaging machine to evaluate performance over a designated time period. Due to outstanding results, within months Lamb Weston had invested in the retrofit of QPH sealing technology on the remaining bagging machines across their whole packaging production line, and saw a significant percentage decrease in film use immediately.
