(Problem) The present invention is interleaved between glass substrates, which are made of a foam sheet having a thin thickness, light weight, strong elasticity, and excellent surface protection, and which can prevent adhesion to glass substrates such as garbage and dust. The purpose is to provide.n n n (Solution means) The slip paper for glass substrates of this invention consists of a polyolefin resin extrusion foam sheet of 0.3-1.5 mm in thickness, and an external density of 18-180 g / L, A polymer type antistatic agent is a polyolefin type in the foam sheet. It is added in the ratio of 5-30 weight part with respect to 100 weight part of resin, The melt sheet has melt tension of 3-40 cN, melt melt flowrate is 0.2-10 g / 10min, and it is the thickness direction of a foam sheet The number of bubbles is 4-10 pieces / mm, the bubble flatness is 0.1-0.6, the surface centerline average roughness is 25 micrometers or less, and the surface resistivity after the ultrasonic cleaning using ethanol is 1 * 10 < 8> -1 * 10 < 14> ( ohm). |
