    摘要: The invention relates to a method for the extrusion and labelling of a packaging tube (14), comprising the following successive steps performed on an extrusion-labelling line, namely: a) forming a partially or fully tubular label (17) from a film (12); b) introducing the label (17) into a calibration element (22); c) extruding a tubular body (13) on the side of the concave surface of the label (17); d) bringing the external surface of the tubular body (13) into contact with the concave surface of the label (17), step (c) being performed in the calibration element (22). The invention also relates to an extrusion-labelling device and a packaging tube.
