Abstract

A glass-resin laminate comprises an elongate glass film having a thickness of 1 to 300 μm, and a peelable elongate resin film having a thickness of 1 to 300 μm and a tensile modulus of elasticity of 0.3 Gpa or more. The elongate resin film is laminated on at least one surface of the elongate glass film so that the elongate resin film protrudes from edges on both sides in a lateral direction of the elongate glass film.

First claim

The invention claimed is:

1. A glass roll, which is constituted by winding a glass film laminate, wherein the glass film laminate comprises:
an elongate glass film having a thickness of 1 to 300 μm and a length of 1000 mm or more; and
an elongate resin film having a thickness of 1 to 300 μm and a tensile modulus of elasticity of 0.3 Gpa or more, and a pressure-sensitive adhesive layer formed on one surface of the elongate resin film,
wherein the elongate resin film is laminated on one surface of the elongate glass film so that the elongate resin film with a tension is peelably adhered to the one surface of the elongate glass film via the pressure-sensitive adhesive layer and protrudes from edges of the elongate glass film on both sides in a lateral direction,
wherein each of protruding portions of the elongate resin film that protrude from the edges of the elongate glass film has a protruding dimension of 5 to 100 mm.

2. The glass roll according to claim 1 , wherein the pressure-sensitive adhesive layer of the elongate resin film has a pressure-sensitive adhesive force of 1×10 −3 to 5×10 −1 N/10 mm.

3. The glass roll according to claim 1 , wherein the elongate glass film has a width of 5 mm or more.

4. The glass roll according to claim 1 , wherein the elongate glass film has a thickness of 1 to 200 μm.

5. The glass roll according to claim 1 , wherein the glass film laminate is wound so that the elongate resin film comes outside.

6. The glass roll according to claim 1 , wherein, between the protruding portions of the elongate resin film that are adjacent to each other in a radial direction of the glass roll, the protruding portions peelably adhere to each other via the pressure-sensitive adhesive layer.

7. A method of producing a glass roll, the method comprising:
producing a glass-resin laminate by laminating an elongate resin film, which has a thickness of 1 to 300 μm and a tensile modulus of elasticity of 0.3 GPa or more, and which has a pressure-sensitive adhesive layer formed on one surface of the elongate resin film, on at least one surface of an elongate glass film which has a thickness of 1 to 300 μm and a length of 1000 mm or more, so that the elongate resin film with a tension is peelably adhered to the one surface of the elongate glass film via the pressure-sensitive adhesive layer and protrudes from edges of the elongate glass film on both sides in a lateral direction, wherein each of protruding portions of the elongate resin film that protrude from the edges of the elongate glass film has a protruding dimension of 5 to 100 mm; and
winding the glass-resin laminate in a roll shape.

8. The method of producing a glass roll according to claim 7 , wherein the laminating of the elongate resin film on the elongate glass film is performed while a tension is applied to the elongate resin film.
