A non-chargeable or weakly chargeable layer structure suitable to be used in, e.g., packages for electronic products and daily consumer goods, as well as a method for producing it. According to the present invention the layer structure comprises a first electrically non-conductive polymer layer, a second electrically non-conductive polymer layer, which is placed at a distance from the first polymer layer, as well as a third layer between the first and second layer, which third layer is at least partly electrically conductive. According to the invention the third layer contains an ionically conductive polymer, whereby the charge decay time of the layer structure is less than 10 s determined according to Standard IEC 61340-5-1 and the surface resistivity of the layer structure is the same or essentially the same as the material of the surface layer. |
