Patent number: 11285708Abstract: Heat resistant brittle films can be made from impact-modified poly(meth)acrylimide, and forgery prevention labels can contain the heat resistant brittle films. The films can be advantageously prepared by extrusion and, depending on the desired purpose, can be designed to be transparent, translucent, or entirely non-transparent, e.g., white. Ideally, the brittle films and the forgery prevention labels containing the brittle films have no intended break points such as slits, perforation, etc.Type: GrantFiled: February 7, 2020Date of Patent: March 29, 2022Assignees: Röhm GmbH, Roehm America LLCInventors: Ghirmay Seyoum, Markus Parusel, Kim Struwe, Anderson Costa, Claude Guénanten, Helmut Häring

Patent number: 8092731Abstract: The invention relates to a method for producing a thermoplastic plastic film. According to said method, the thermoplastic plastic is melted and transported in an extrusion installation comprising an extruder, an extrusion nozzle with a wide-slot delivery opening and a chill roll, which is fixed to a roll system and then leaves the delivery opening of the extrusion nozzle in the form of a flat melted web. Said melted web is then applied to the chill roll and is cooled. The invention is characterised in that it uses an extrusion installation, in which the distance between the delivery opening of the extrusion nozzle and the surface of the cooled roll does not vary by more than +/?50 ?m during the operating time. The invention also relates to a film of this type and to uses of the latter.Type: GrantFiled: November 24, 2005Date of Patent: January 10, 2012Assignee: Röhm GmbHInventors: Claude Guenanten, Christoph Steinfels, Herbert Groothues, Christoph Krohmer, Helmut Haering, Detlef Birth, Christopher Neuroth, Michael Meier-Kaiser, Walter Meon
