The present invention relates to a roller device for treating sheet-form material, in particular for smoothing films (F*) or sheets, comprising a first roller unitand a second roller unit, wherein each roller unit () comprises: where where n: speed of the drive motor and n: speed of the roller (). The invention relates further to a smoothing device for smoothing films or sheets, and to a process for the production of sheet-form material, in particular of films or sheets.

Roller device for treating flat material, in particular for smoothing foils or plates, smoothing device, and method for producing flat material, in particular foils or plates

A film comprising a matrix of transparent polymeric resin, and polymeric particles is disclosed. The particles are characterized in that their refractive index is different from that of the polymeric resin and in that their average particle size is 1 and 100 &#x3bc;m. One surface of the film is structured its 60&#xb0; gloss value is greater than 0.5 and smaller than 20%, and its roughness is greater than 3 and lower than 25 &#x3bc;m. The other surface has a 60&#xb0; gloss value greater than 50%. The film is suitable for use in flat screens.
