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.
Claims14
A method of forming a credential card, comprising:
- positioning a first thermoplastic layer in a stacked arrangement with a first release sheet;
- applying a cross-linkable polymer composition to the first thermoplastic layer;
- positioning an inlay layer in a stacked arrangement with the first thermoplastic layer and the first release sheet, wherein the inlay layer is in direct contact with the first thermoplastic layer and the cross-linkable polymer composition, and wherein the inlay layer defines at least one cavity;
- positioning a first circuit element within the at least one cavity defined by the inlay layer, wherein the first circuit element comprises a printed circuit board having at least one electronic component formed on a supporting film and an antenna;
- positioning a second release sheet in a stacked arrangement with the first thermoplastic layer, first release sheet, and inlay layer to form a layered structure;
- applying a predetermined pressure to the layered structure;
- and
- heating the layered structure to a temperature sufficient to at least partially cure the cross-linkable polymer composition to form a credential core.

A credential card core, comprising:
- a first thermoplastic layer;
- a cross-linkable polymer composition disposed on at least a portion of the first thermoplastic layer;
- an inlay layer positioned in a stacked 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, and wherein the inlay layer defines at least one cavity;
- and
- a first circuit element positioned within the at least one cavity defined by the inlay layer, wherein the first circuit element comprises a printed circuit board having at least one electronic component formed on a supporting film and an antenna.

A method of forming a credential card, comprising:
- positioning a first thermoplastic layer in a stacked arrangement with a first release sheet;
- applying a cross-linkable polymer composition to the first thermoplastic layer;
- positioning an inlay layer in a stacked arrangement with the first thermoplastic layer and the first release sheet, wherein the inlay layer is in direct contact with the first thermoplastic layer and the cross-linkable polymer composition, and wherein the inlay layer defines at least one cavity;
- positioning a first circuit element within the at least one cavity defined by the inlay layer, wherein the first circuit element comprises a printed circuit board having at least one electronic component formed on a supporting film and an antenna;
- positioning a second release sheet in a stacked arrangement with the first thermoplastic layer, first release sheet, and inlay layer to form a layered structure;
- applying a predetermined pressure to the layered structure;
- heating the layered structure to a temperature sufficient to at least partially cure the cross-linkable polymer composition to form a credential core;
- and
- laminating, subsequent to heating the layered structure, a card stack under a predetermined pressure at a predetermined temperature to form a credential card, wherein the card stack comprises the credential core and at least one additional thermoplastic layer.
