Abstract
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.

An extruded and labelled packaging tube, the packaging tube manufactured by the steps of:
- forming a partially or fully tubular label from a film;
- introducing the tubular label into a calibration device;
- extruding a tubular body on a side of a concave surface of the tubular label;
- and
- bringing an external surface of the tubular body into contact with the concave surface of the tubular label,
- wherein the step of extruding is performed in the calibration device, and
- wherein the film is welded or embedded in a wall of the tubular body.
An extruded and labelled packaging tube comprising:
- a tubular body made of thermoplastic resin;
- and
- a tubular label having a concave surface, the concave surface being in contact with the tubular body by extrusion of the thermoplastic resin against the concave surface of the tubular label.
