Abstract
A method for producing a laminated glass pane that includes a first pane, a first laminating film, a polymer film, a second laminating film, and a second pane, in this order, wherein the polymer film is bonded to the two laminating films, in which method the starting material for the first and the second laminating film is in each case a laminating film in roll form, which, before being used to form the laminated glass pane, is subjected to a pretreatment, in which the laminating film is relaxed by a heat treatment in a non-tensioned state.
