Zusammenfassung:Production method for the manufacturing of very thin monolithic layers (7) of thermoplastic polyurethane (TPU) characterized in that the TPU is extrusion coated and/or laminated with an extrusion head (1) with a mouth opening of less than 0.80 mm, and preferably of 0.60 mm, whereby the line speed is held between 50 m/min and 200 m/min, and preferably at 100 m/min, and whereby the extruder head temperature is held between 150 °C and 270 °C, and preferably at 175 °C, and whereby the extruder compression ratio is held between 3.0 and 3.8, and preferably at 3.5, and whereby the pressing pressure of the extruder is kept between 10 bar and 80 bar, and preferably at 40 bar.
