<p>A method for forming a packaging material in multi-layer band ( 2 ) includes feeding a first band ( 3 ) of thermo formable material and at least a second band ( 4 ) along respective first and second feeding paths (P 1, P 2 ), which extend through a station ( 10 ) for joining the first band ( 3 ) and the second band ( 4 ). The bands ( 3, 4 ) are joined, by sealing, in the joining station ( 10 ), in order to obtain a third, multi-layer band ( 2 ) fed along a third feeding path (P 3 ). Moreover, the method includes another step, during which at least one of the bands ( 3, 4, 2 ) undergoes a process for defining a visual, three-dimensional effect image on the band.</p> |
