The invention relates to a film structure (10, 30, 40, 60) comprising a polymer film (1) and an application system enabling the film structure to be handled in a simple manner. The application system is arranged on a first side of the polymer film (1) and comprises at least one supporting film (14, 20, 34, 44c, 64c) to which at least one gripping strip (15, 25, 35, 45, 65) is applied. The supporting film (14, 20, 34, 44c, 64a) comprises a first side facing towards the polymer film (1) and a second side facing away from the polymer film (1), the second side of the support film (14, 20, 34, 44c, 64a) comprising at least one adhesive region (18, 28, 38, 48, 68).
