ABSTRACT:
A polymeric sheet structure consists of an adhesion-promoting coating on at least one surface of the substrate. The adhesion-improving coating is produced by treating this substrate surface with an electrical corona discharge between high voltage electrodes and a grounded counter-electrode while simultaneously spraying an aerosol into the corona discharge zone. The aerosol contains, for example, an aqueous emulsion of thermoplastic and/or crosslinkable components as an adhesion-promoting agent.
