Flexible hose with a QR code

A method for manufacturing a flexible hose for the transportation of liquids or fluids, the method comprising the steps of:

• providing at least one QR code strip comprising a transfer strip and a plurality of QR codes, the transfer strip being made of a polymeric strip material and having a length, the plurality of QR codes being QR codes according to the ISO/IEC 18004:2000 (E) standard and being arranged spaced apart from one another at a predetermined distance, each QR code of said plurality of QR codes consisting of a respective at least one ink layer;
• extruding a first polymeric material by means of an extrusion head to obtain a flexible hose having at least one layer comprising an exposed surface, the extrusion head comprising an outlet and the exposed surface having a length;
• coupling said at least one QR code strip to said exposed surface at the outlet of said extrusion head so as to hot transfer said QR codes onto respective portions of said exposed surface along the length of the exposed surface, said coupling comprising contacting the QR codes to the exposed surface;
• and
• removing said at least one transfer strip from the exposed surface without removing the plurality of QR codes from the exposed surface,
• wherein the polymeric strip material of said QR code strip is incompatible with said first polymeric material, and the at least one ink layer is compatible with said first polymeric material.
