Abstract

A laminated transaction card may comprise post-consumer polyethylene with a thickness of at least 30% of a thickness of the laminated transaction card. A first polymer-based layer comprising polyvinyl chloride is coupled to a first surface of the core layer by a first adhesive layer. A second polymer-based layer comprising polyvinyl chloride is coupled to a second surface of the core layer by a second adhesive layer. The first adhesive layer and the second adhesive layer comprise an adhesive formulated to bond the post-consumer polyethylene and the polymer-based layers.

Claims (29)

1. A laminated transaction card comprising:

a core layer comprising at least 50% recycled polyethylene by weight with a thickness of at least 30% of a thickness of the laminated transaction card;

a first polymer-based layer comprising polyvinyl chloride coupled to a first surface of the core layer by a first adhesive layer; and

a second polymer-based layer comprising polyvinyl chloride coupled to a second surface of the core layer by a second adhesive layer;

wherein the first adhesive layer and the second adhesive layer comprise an adhesive formulated to bond the recycled polyethylene and the polymer-based layers.

2. The laminated transaction card of claim 1 , further comprising:

a first print layer formed on an outer surface of the first polymer-based layer; and

a second print layer formed on an outer surface of the second polymer-based layer.

3. The laminated transaction card of claim 1 , further comprising:

an integrated circuit chip disposed within a pocket defined in the first polymer-based layer.

4. The laminated transaction card of claim 1 , further comprising:

a first outer support layer interconnected to the first polymer-based layer by a first outer thermosetting adhesive layer; and

a second outer support layer interconnected to the second polymer-based layer by a second outer thermosetting adhesive layer.

5. The laminated transaction card of claim 1 , further comprising:

an antenna formed on the first surface of the core layer.

6. A method of producing a laminated transaction card, the method comprising:

treating a first surface and a second surface of a core layer so as to increase the surface energy of the core layer, wherein the core layer comprises at least 50% recycled polyethylene by weight;

positioning a first support layer and a second support layer on opposing sides of the core layer, wherein a first adhesive layer is positioned between the first polymer-based layer and the first surface of the core layer and a second adhesive layer is positioned between the second support layer and the second surface of the core layer; and

activating the first adhesive layer and the second adhesive layer to bond the first support layer to the first surface of the core layer and to bond the second support layer to the second surface of the core layer.

7. The method of claim 6 , wherein activating the first adhesive layer and the second adhesive layer comprises applying heat and pressure to the first adhesive layer and the second adhesive layer.

8. The method of claim 7 , wherein the heat applied to the first adhesive layer and the second adhesive layer is above an activation temperature of the first adhesive layer and the second adhesive layer and above a glass transition temperature of the first support layer and the second support layer.

9. The method of claim 6 , further comprising:

applying a first print layer to an outer surface of the first support layer and a second print layer to an outer surface of the second support layer; and

applying heat to the first print layer and the second print layer to bond the first print layer to the first support layer and the second print layer to the second support layer.

10. The method of claim 6 , wherein treating the first surface and the second surface of the core layer to increase the surface energy of the core layer comprises applying a corona treatment to the first surface of the core layer and the second surface of the core layer.

11. The method of claim 6 , wherein activating the first adhesive layer and the second adhesive layer comprises applying varying heat and pressure to the first adhesive layer and the second adhesive layer over predetermined periods of time.

12. The method of claim 6 , wherein the first adhesive layer and the second adhesive layer are formulated to bond to both recycled polyethylene and polymer-based materials.

13. The method of claim 6 , wherein the core layer further comprises an antenna in contact with the first surface of the core layer.

14. The method of claim 13 , wherein the antenna is placed on the first surface of the core layer in accordance with an expected deformation of the core layer.
