<p>PROBLEM TO BE SOLVED: To provide a polyethylene-based resin foamed sheet for an insert paper sheet excellent in cushion ability, on which a glass plate is not slippery.SOLUTION: A polyethylene-based resin foamed sheet for an insert paper sheet has a thickness of 0.15-0.50 mm, a basis weight of 15-50 g/m, a surface specific resistance of 10-10Ω/sq, an arithmetic average surface roughness of 25-50μm, a maximum height of surface roughness of 120-250μm, an average length of a contour curve element of surface roughness of 200-600μm, a value obtained by diving a thickness by the maximum height of surface roughness of 1.3-3.</p> |
