Abstract: A foil assembly of a printed product includes a metallic layer and a polymer layer. The metallic layer forms conductive bodies that can be detected by a touch-sensitive device. The polymer layer is coupled with the metallic layer and includes a pigment that is reflective and/or opaque and a flexible binder material. The polymer layer absorbs changes in shape of an adhesive between the foil assembly and the printed product apparatus to prevent cracking. The foil assembly may include a tie coat layer that couples the metallic layer with the adhesive and/or another tie coat layer on the other side of the metallic layer which bonds to first side of a second metallic layer. The second side of the second metallic layer includes a tie coat that couples the complete assembly with the adhesive of the printed product apparatus.
