Abstract: The invention relates to an insert for a passport booklet data sheet, formed by a multilayer complex having at least a first layer and a second layer having a hinge that has a folding zone where the insert is intended to be sewn or stapled into a passport booklet, said second layer having, in combination, at least one layer of plastics material and at least one metal reinforcing layer that together form an extension which extends a certain distance beyond said folding zone of the hinge, so as to reinforce the resistance of said data sheet to being ripped out and torn with respect to the passport booklet, characterized in that said layer of plastics material and said metal reinforcing layer extend over the entire surface area of the insert.

Abstract: The antenna-forming insert for a chip card includes a central layer forming an antenna including a substrate and at least one conductor extending along at least one face of the substrate. At least one cover layer covering on at least one side the central layer and capable of compensating for the irregularities of the surface of the central layer. Each cover layer includes a proximal sheet located in proximity to the central layer and a distal sheet located away from the central layer, both sheets being superposed and laminated and the proximal sheet during the lamination phase has lower fluidity than that of the distal sheet.
