FIG. 2 is a cross-section view of an exemplary embodiment of shielded wallpaper 22 of FIG. 1 along line A-A. As depicted in the magnified cross-section, the exemplary shielded wallpaper 22 comprises a metal-CVD coated substrate core 24 that is impregnated by resin 26. The resin 26 in the depicted embodiment has an impregnating portion and also forms an obverse layer 28 and a reverse layer 30 of resin 26 only, and an intermediate layer 32 comprised of the resin-impregnated (the impregnating portion) metal-CVD coated substrate core 24. With this configuration, not only does the resin 26 add strength and durability to the metal-CVD coated substrate core 24, but it also seals the metal-CVD coating or the substrate core 24 from corrosion while creating vapor impermeability and maintaining the shielding capability of the shielded wallpaper 22. It should be understood that the obverse layer 28 and reverse layer 30 may each be very thin (i.e, sufficient to seal metal-CVD coated substrate core 24). The depictions of the obverse layer 28 and reverse layer 30 in the drawings have exaggerated thickness only for illustration and disclosure purposes.
