Process for the production of flat parts, in particular plastic films, by means of extrusion, flat part produced by extrusion, in particular plastic film, and device for extruding flat parts, in particular plastic films

摘要

Flat sheets, especially synthetic films, of at least two different materials are extruded in the molten state from an extrusion nozzle. The different materials are placed side by side essentially in the direction of transverse stretching (B) of the sheet (50) across the extrusion direction (A).
