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. A crosslinkable polymer composition comprises a curable base polymer resin in a liquid or paste form, and a particulate thermoplastic filler. The base polymer resin is selected from the group consisting of urethane acrylate, silicone acrylate, epoxy acrylate, urethane, acrylate, silicone and epoxy. The particulate thermoplastic filler may be polyolefin, polyvinyl chloride (PVC), a copolymer of vinyl chloride and at least another monomer, or a polyester such as polyethylene terephthalate (PET), a compound or blend thereof.

1. A method for forming a core layer of an information carrying card, comprising: forming a first thermoplastic layer defining at least one cavity extending from a major surface, the first thermoplastic layer comprising at least one thermoplastic material;disposing an inlay layer comprising printed circuit board (PCB) partially or fully into the at least one cavity, the inlay layer comprising at least one integrated circuit, at least one wire and a supporting film; anddispensing a crosslinkable polymer composition partially or fully over and directly contacting the inlay layer in the at least one cavity so as to form said core layer of the information carrying card, the crosslinkable polymer composition comprising: a curable base polymer resin in a liquid or paste form, the base polymer resin selected from the group consisting of urethane acrylate, silicone acrylate, epoxy acrylate, methacrylate, silicone, urethane and epoxy; anda particulate thermoplastic filler. 2. The method for forming a core layer of an information carrying card of claim 1 further comprising: providing a first release film;placing a second release film above the first release film;and placing the first thermoplastic layer having at least one cavity above the second release film before disposing the inlay layer in the at least one cavity. 3. The method for forming a core layer of an information carrying card of claim 2 further comprising: placing a third release film over the inlay layer after dispensing the crosslinkable polymer composition in the at least one cavity; andplacing a fourth release film above the third release film and forming a sandwich structure. 4. The method for forming a core layer of an information carrying card of claim 3 wherein the first and the fourth release films are the same, and the second and the third release films are the same. 5. The method for forming a core layer of an information carrying card of claim 3 wherein the second and the third release films are a breathable release film. 6. The method for forming a core layer of an information carrying card of claim 3 further comprising: pressing the sandwich structure under a pressure. 7. The method for forming a core layer of an information carrying card of claim 6 wherein the pressure is less than 2 MPa. 8. The method for forming a core layer of an information carrying card of claim 6 further comprising: heating the sandwich structure at a raised temperature under the pressure;cooling the sandwich structure; andpeeling off the first, second, third and fourth release films. 9. The method for forming a core layer of an information carrying card of claim 6 wherein the raised temperature is less than 150° C. 10. The method for forming a core layer of an information carrying card of claim 1 further comprising: forming a plurality of holes by cutting a plurality of portions of the supporting film without damages to any of the at least one wire and the at least one integrated circuit on the inlay layer, before disposing the inlay layer of PCB into the at least one cavity on the first thermoplastic layer. 11. The method for forming a core layer of an information carrying card of claim 10 further comprising: fixing the inlay layer onto the first thermoplastic layer by applying an instant adhesive in the plurality of holes of the inlay layer, before dispensing the crosslinkable polymer composition over the inlay layer. 12. The method for forming a core layer of an information carrying card of claim 11 wherein the instant adhesive comprises cyanoacrylate. 13. The method for forming a core layer of an information carrying card of claim 1 wherein forming the first thermoplastic layer having at least one cavity comprises: die-cutting one or more thermoplastic films; andlaminating the one or more thermoplastic films under a heating condition. 14. The method for forming a core layer of an information carrying card of claim 1 wherein the size of the at least one cavity on the first thermoplastic layer is larger than the size of the inlay layer of PCB. 15. The method for forming a core layer of an information carrying card of claim 1 wherein the size of the at least one cavity on the first thermoplastic layer is substantially the same as the size of the inlay layer of PCB. 16. The method for forming a core layer of an information carrying card of claim 1 wherein the size of the at least one cavity on the first thermoplastic layer is substantially the same as the size of a portion of the inlay layer of PCB. 17. The method for forming a core layer of an information carrying card of claim 3 wherein the first thermoplastic layer having at least one cavity comprises a thermoplastic material selected from polyvinyl chloride, copolymer of vinyl chloride, polyolefin, polycarbonate, polyester, polyamide, and acrylonitrile butadiene styrene copolymer (ABS). 18. The method for forming a core layer of an information carrying card of claim 3 wherein the curable base polymer in the crosslinkable polymer composition is urethane acrylate. 19. The method for forming a core layer of an information carrying card of claim 3 wherein the particulate thermoplastic filler in the crosslinkable polymer composition comprises PVC or a copolymer of vinyl chloride and at least another monomer. 20. The method for forming a core layer of an information carrying card of claim 19 wherein the particulate thermoplastic filler in the crosslinkable polymer composition comprises a copolymer of vinyl chloride and at least another monomer selected from the group consisting of vinyl ester, vinyl acetate and vinyl ether. 21. The method for forming a core layer of an information carrying card of claim 20 wherein the particulate thermoplastic filler in the crosslinkable polymer composition is a PVC modified with a copolymer of vinyl chloride and at least another monomer selected from the group consisting of vinyl ester, vinyl acetate and vinyl ether. 22. The method for forming a core layer of an information carrying card of claim 6 further comprising curing the crosslinkable polymer under a UV light. 23. A method for fabricating an information carrying card, comprising forming a core layer of the information carrying card according to claim 1. 24. A method for fabricating an information carrying card of claim 23 further comprising laminating a printable thermoplastic film on each side of the core layer of the information carrying card. 25.
