GLASS FILM HAVING A DEFINED EDGE CONFIGURATION

摘要

A glass film has a thickness of less than 1.2 mm, and a first and a second surface, both surfaces being defined by edges having an edge surface. The respective edge surfaces are provided with a microstructure surface, including micro-cracks and fissures which are laterally defined by flanks. At least two edges located opposite one another include a low viscosity adhesive having a viscosity of less than 600 mPas at 23° C., on their microstructure surfaces in such a way that the respective flanks of the micro-cracks and fissures are bonded together using an adhesive so that the probability of failure of the glass film having a length of 1000 m and a thickness in the range of 5 μm to 350 μm, and a diameter of a wound glass film roll in the range of 50 mm to 1000 mm is less than 1%.

1. A glass film having a thickness of less than 1.2 millimeter (mm), comprising a first surface and a second surface, each of said first surface and said second surface being defined by a plurality of edges, each of said edges having a respective edge surface including a microstructure surface having a plurality of micro-cracks and fissures laterally defined by a plurality of flanks, at least two of said plurality of edges located opposite one another including a low viscosity adhesive having a viscosity of less than approximately 600 milliPascals (mPas) at 23° C. on said respective microstructure surface of each of said at least two edges such that said flanks of said micro-cracks and fissures are bonded together with said adhesive so that a probability of failure of the glass film having a length of 1000 meters (m), a thickness in a range of between approximately 5 micrometers (μm) and 350 μm, and a diameter of a roll of the glass film in a range of between approximately 50 mm and 1000 mm, is less than 1%.
