A laminated multilayer film substrate for use in the production of banknotes having an oriented polypropylene core layer and at least one high density polyethylene layer on each side of the oriented polypropylene layer. The core layer may contain microcavities formed by the addition of a cavitating agent. The outer surfaces of the multilayer film substrate are coated with one or more epoxy layers, filed or unfilled, and one or more antistatic layers. The resultant films exhibit good embossability, dead-fold characteristics and other properties, making them highly suited for the production of bank notes and other security documents.
