Process for producing laminated glass plates free of optical disturbances caused by V bending, use of special carrier foils used in the manufacture of laminated glass plates, and carrier foils particularly suitable for the above methods and applications

摘要

The present invention relates to a method for producing a laminated glass plate free of optical obstacles caused by bending in reflected light and projected light. The laminated glass plate includes a first glass plate, a second glass plate and a multilayered interlayer, wherein the multilayered interlayer comprises a first laminated foil, a thin film-based, two-axially stretched thermoplastic carrier foil, and a second laminated foil. It is provided. The carrier foil, which is a thin film system, is disposed on the first laminated foil. The carrier foil has a thickness of 30 to 70 µm and a heat shrinkage of 0.3 to 0.8% in both stretching directions when measured after heat treatment at 120 ° C. for 20 seconds. The second laminated foil is placed over the carrier foil. The foil bonded together between the two glass plates is arranged using heat and pressure to crimp freely. Suitable carrier foils for the production of laminated glass plates and their use are described.
