Langzeitbiegbares glass material, and to methods for producing a glass material langzeitbiegbaren

The invention relates to a langzeitbiegbares glass material preferably in the form of a thread wound on a reel glass material, particularly a glass ribbon having a thickness of less than 500 microns, preferably at most 350 microns and a minimum thickness of 5 microns, in particular in the range 20 microns to 200 microns. The invention is characterized in that the langzeitbiegbare glass material is such that the number, which over time developing fractures N of the bent glass with a bending radius R in the range 1 mm to 10
