Multilayer film ( 1 ) with electrically switchable optical properties, comprising, arranged sheet-wise in order, at least: —a first carrier film ( 5 ), —a first electrically conductive layer ( 3 ), —an active layer ( 2 ), —a second electrically conductive layer ( 4 ) and—a second carrier film ( 6 ), wherein—the multilayer film ( 1 ) has at least two circumferential separating lines ( 16 ), which separate an insulated edge region ( 18 ) from the first electrically conductive layer ( 3 ) and the second electrically conductive layer ( 4 ), —the first carrier film ( 5 ) and the second carrier film ( 6 ) are welded in at least a part of the insulated edge region ( 18 ) to form a sealed region ( 7 ), and—the separating lines ( 16 ) have a width of 10 μm to 500 μm. |
