Web\$\begingroup\$ You would need to know the relative thicknesses of the two materials. Dielectric constants are in Farad/Meter (using a cubical model like resistivity), so you can substitute the thickness to get F/M^2. Then the combination is essentially two caps in series, and you can derive resultant F/M for your sheet. \$\endgroup\$
