A new feedblock has been developed by AMU, headquartered in Marano Ticino (Novara, Italy) for the co-extrusion of sheets used for thermoformed food containers. The feedblock was designed to ensure a flow-channel geometry free of stagnation zones or localized slowdown and therefore prevent any counter-pressure against upstream extruders. Moreover, the system includes a lamination unit that is interchangeable both regarding materials and the different structure of the sheets to be produced.
