发明名称 METHOD FOR PRODUCING A FILM COMPOSITE MATERIAL AND A CARD BODY
摘要 A method for producing a foil composite material, in particular for use as a layer in a card body, preferably in a card body of a portable data carrier, whereby using a coextrusion process, at least a first plastic melt of plastic including a thermoplastic elastomer and at least a second plastic melt of plastic without a thermoplastic elastomer, are joined in such a fashion that a foil composite material is formed.
