Abstract
The disclosure provides a cross-linkable polymer composition, a core layer for an information carrying card comprising such cross-linked composition, resulting information carrying card, and methods of making the same. An information carrying card includes a body defining a first cavity and a second cavity. The first cavity has a first area and the second cavity has a second area. The first cavity is continuous with the second cavity and the second area is less than the first area. A circuit element is disposed within the first cavity.
Claims24
A method for forming a plurality of information cards comprising:
- applying a first thermoplastic layer having a first cavity;
- providing an inlay layer with a plurality of holes so as to be fully disposed in the first cavity, the inlay layer comprising a metal and at least one of an active and passive component positioned in relation to a hole defined by the inlay layer;
- applying a cross-linkable polymer composition to the first thermoplastic layer;
- positioning the inlay layer in a sandwich arrangement with the first thermoplastic layer, wherein the inlay layer is in direct contact with the first thermoplastic layer and the cross-linkable polymer composition;
- applying a predetermined pressure to the layered structure;
- positioning a printable layer on the surface of the first thermoplastic sandwich structure;
- and
- heating the sandwich structure to a temperature sufficient to at least partially cure the cross-linkable polymer composition to form one or more information cards.
A plurality of information cards, each comprising:
- a first thermoplastic layer having a first cavity;
- an inlay layer with a plurality of holes so as to be fully disposed in the first cavity, the inlay layer comprising a metal and at least one of an active and passive component positioned in relation to a cavity defined by the inlay layer;
- a cross-linkable polymer composition contacting the first thermoplastic layer;
- wherein the inlay layer is arranged in a sandwich arrangement with the first thermoplastic layer, so that the inlay layer is in direct contact with the first thermoplastic layer and the cross-linkable polymer composition;
- a printable layer on the surface of the first thermoplastic sandwich structure so that when the sandwich is heated to a temperature sufficient to at least partially cure the cross-linkable polymer composition the information card is formed.
