Abstract
A method for manufacturing a plastic fabric-film composite product includes forming an extruded-film web with at least one sealing layer by film extrusion in such a way that the sealing layer is located on a first side of the extruded-film web and then, feeding and laminating a plastic-fabric web made of film-strip fabric and the prefabricated extruded-film strip with one another to form a composite web. The composite web is formed in such a way that a second side of the extruded-film web faces a first side of the plastic-fabric web.
