A structural adhesive film, comprising - at least one adhesive layer, - the adhesive layer comprising at least one epoxy compound and at least one epoxy curing agent; - the film further providing a major upper surface (35) as well as an opposing major lower surface (36), - and the film having an extension in a longitudinal direction (y) which is larger than its extension in a cross direction (x) wherein - in a cross-sectional view of the film the distance between the two opposing major surfaces (35 and 36) varies along the extension of the cross direction (x) such that the film provides at least two distances between the opposing major surfaces, a first distance d1 and a second distance d2, wherein the distance d2 is at least 10% larger than the distance d1. The structural adhesive film is used for bonding panels together to form a panel assembly, wherein the panels are bond to each other through a hemmed structure and wherein the structural adhesive film is positioned between the two panels in the hemmed structure and fills the space between the two panels in the hemmed structure before the structural adhesive film is cured.
