Abstract (en)
[origin: WO0074936A1] 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 contains microcavities formed by the addition of a cavitating agent. The resultant films exhibit good embossability, dead-fold characteristics and other properties, making them highly suited for the production of banknotes and other security documents.
