Films or plates made of a plastic mixture and capable of being metal-plated are disclosed, comprising, in relation to the total weight of components A, B, C and D, which add up to 100 % by weight: (a) 5-50 % by weight of a thermoplastic polymer as component A; (b) 50-95 % by weight of a metal powder having an average particle diameter ranging from 0.01-100 νm (determined by the method defined in the description), the metal having a more negative normal potential in an acid solution than silver, as component B; (c) 0-10 % by weight of a dispersant as component C; and (d) 0-40 % by weight fibrous or particulate fillers or their mixtures as component D. The elongation at tear of component A (determined by the method defined in the description) is 1.1-100 times higher than the elongation at tear of the plastic mixture comprising components A, B and optionally C and D (determined by the method defined in the description). The tensile strength of component A (determined by the method defined in the description) is 0.5-4 times higher than the tensile strength of the plastic mixture comprising components A, B and optionally C and D (determined by the method defined in the description). Also disclosed are thermoplastic moulding compounds for producing these films or plates that can be metal-plated, a granulate comprising these thermoplastic moulding compounds, stratified composite films or plates and mouldings comprising these films or plates, metal-plated polymer bodies comprising these films or plates, stratified composite films or plates and mouldings, processes for producing these objects, the use of these objects as EMI shieldings and absorbers, dampers or reflectors for electromagnetic radiation, oxygen scavengers, electroconducting components, gas barriers, and decorative elements comprising these objects.
