Plastic sheet, method for producing plastic sheet, interlayer film for laminated glass and laminated glass

摘要

Provided are a plastic sheet and an interlayer film for laminated glass, which can hardly cause delamination of the laminated glass and can further improve the penetration resistance of the laminated glass. The plastic sheet used for the interlayer film for laminated glass according to the present invention is a plastic sheet used for the interlayer film for laminated glass, and includes a first surface and a second surface opposite to the first surface. The first surface and the second surface are coated with a surface treatment agent or modified by a surface treatment so that the wetting tension is 40 mN / m or more.
