The present invention relates to a functional film, a method for manufacturing the same and a
laminated glass product. The functional film comprises a first carrier film, a first
electrode layer, a functional layer, a second
electrode layer and a second carrier film arranged in this order, wherein the edges of the first carrier film are connected to the edges of the second carrier film by edge sealing to encapsulate an active area of the functional layer within a central area, wherein within the central area the first
electrode layer is provided with at least one first
busbar and at least one first isolation area electrically isolated from the rest of the first electrode layer, and the second electrode layer is provided with at least one second
busbar and at least one second isolation area electrically isolated from the rest of the second electrode layer, wherein the first
busbar is positioned to at least partially overlap the second isolation area and the second busbar is positioned to at least partially overlap the first isolation area. The manufacturing process of the functional film is simple and fast, and the overall structure obtained is robust and low cost.
