GLASS FILM HAVING A SPECIALLY DESIGNED EDGE

摘要

The invention relates to glass film having a thickness of less than 1.2 mm, in particular in the range of 5 µm to 200 µm, having a first and a second surface, both surfaces being defined by edges having an edge surface, wherein the respective edge surfaces are provided with a micro structure having a microstructure surface, comprising micro fractures and fissures, which are laterally defined by flanks. The invention is characterized in that at least two edges located opposite one another comprise a low viscosity adhesive, the viscosity thereof being smaller than 600 mPas at 23⁰ C, in particular smaller than 150 mPas at 23⁰ C, preferably in the range of 0.5 mPas to 600 mPas at 23⁰ C, very preferably in the range of 0.5 mPas to 250 mPas at 23⁰ C, especially preferably from 1 mPas to 80 mPas at 23⁰ C, in particular most preferably from 25 mPas to 80 mPas at 23⁰ C, on the microstructure surfaces thereof such that the respective flanks of the micro fractures and fissures are glued together by means of the adhesive so that the default probability of the glass film at a length of 1000 m and a thickness ranging from 5 µm to 350 µm, in particular from 15 µm to 200 µm, and an angle diameter of the glass film ranging from 50 mm to 1000 mm, in particular ranging from 150 mm to 600 mm, is lower than 1 percent.
