A device or an enclosed area that can cause or is sensitive to
electromagnetic interference (EMI) is shielded by at least partially
surrounding the device or the area with a visible light-transmissive film
comprising a flexible support, an extensible visible light-transmissive
metal or metal alloy layer and a visible light-transmissive crosslinked
polymeric protective layer, and optionally connecting at least one
grounding electrode to the metal or metal alloy layer. The film has
reduced susceptibility to fracture or corrosion compared to commercially
available EMI shielding films, especially when bent or deformed.
