Beschreibung
Zusammenfassung:	In the production of a shaped article, consisting of a spatial extension on a support and a thermoformable plastics film (1) applied to the support, by adhering the film to the support by deep-drawing, the supplied film already has an activable adhesive layer (2) on the support-facing underside and the adhesive is activated before deep-drawing so that the adhesive layer bonds well to the support. An independent claim is included for a single or multi-layer plastics film (1) with an adhesive layer (2) applied during production of the film, for carrying out the process, where the adhesive is activated (rendered tacky) by heating to a temperature markedly above the temperatures to which the film is exposed during transport and storage.
