Abstract
A card formed in accordance with the invention includes a first assembly comprised of multiple plastic layers attached via an adhesive to a metal layer. The multiple plastic layers forming the first assembly are laminated under a first selected temperature and pressure conditions to preshrink the multiple plastic layers, stress relieve the first assembly and render the first assembly dimensionally stable. The laminated first assembly is then attached to a metal layer via an adhesive layer to form a second assembly which is then laminated at a temperature below the first selected temperature to form a card which is not subjected to warpage and delamination.
Claims18
A method of making a card comprising the steps of:
- forming a first assembly of a first predetermined thickness, said first assembly including at least two layers of plastic material;
- firstly laminating the at least two layers of different plastic material at a first predetermined temperature and pressure for forming said first assembly;
- wherein said first lamination step comprises preshrinking the at least two layers of plastic material and reducing subsequent dimensional changes of the layers forming the first assembly;
- secondly forming a second assembly including said first assembly and a metal layer with an adhesive layer between the first assembly and the metal layer;
- and
- laminating the second assembly at a temperature which is lower than the first predetermined temperature.
A method as claimed 1, further including the step of embossing the second assembly after it has been laminated for the purpose of personalizing the card.
A card comprising:
- a first assembly comprised of multiple plastic layers which wherein the multiple plastic layers have been laminated at a first temperature and pressure to preshrink the layers and reduce their subsequent dimensional changes;
- said first assembly having an inner surface and an outer surface;
- the outer surface defining one of the top and bottom side of the card;
- a layer of metal material and an adhesive layer;
- the layer of metal material having an inner surface and an outer surface;
- the inner surface of the layer of metal material being attached to the inner surface of the first assembly via said adhesive layer, the combination of said first assembly, adhesive layer and the metal layer forming a second assembly which is laminated at a temperature which is less than the first temperature, and wherein the outer surface of the layer of metal material defines the other one of the top and bottom side of the card.
