The reinforced longitudinal band is integral with the main portion of the plastic stretch film in a single ply. Furthermore pre stretching the plastic stretch film so that a pre stretched plastic stretch film (1) is formed comprising a final reinforced longitudinal band (8) formed from the reinforced longitudinal band, and the pre stretched plastic stretch film (1) comprising a final main portion (9) formed from the main portion. The final reinforced longitudinal band (8) is thicker than the final main portion (9) and is integral with the final main portion (9) in a single ply.
