  • the film may have already been deformed in advance by deep drawing.
  • this poses the problem that the complex film structure can be easily damaged by the hot liquid plastic.

  • an electroluminescent film is usually back-injected with this in-mold process in such a way that it forms the surface of a component after injection molding.
  • electroluminescent films are usually back-injected with this in-mold process in such a way that it forms the surface of a component after injection molding.
  • the object of the invention is to protect a film layer (in particular an electroluminescent film) that is sensitive to back-injection in an in-mold process and / or to protect a back-sprayed film (in particular an electroluminescent film) from external mechanical stress.

  • This object is achieved according to claim 1 by a method for back-injection of films, at the same time introduced two independent films in an injection mold and an activatable layer which is present on at least one of the two films is activated by the injection molding process, that the films be connected to each other. Furthermore, the object is achieved by a plastic element according to claim 13, which consists of at least two attached to its surface films, of which the film lying directly on the surface by means of an activatable layer with the lower lying and the lower lying is connected by a fusion bond with the remaining plastic element.
