PROBLEM TO BE SOLVED: To provide a multilayer foam sheet which has adequate cushioning property and stiffness strength even when being thinner and lighter than a conventional multilayer foam sheet for interleaf paper, and can be suitably used as interleaf paper of a glass plate for a substrate.SOLUTION: A multilayer foam sheet has a polyethylene-based resin foam layer and an antistatic layer laminated and bonded by coextrusion on both surface sides of the foam layer, and has an apparent density of 30-300 kg/mand a thickness of 0.05-2 mm. A basis weight per one surface of the antistatic layer is 1-10 g/m. The antistatic layer is formed of a mixed resin composition containing a polyethylene-based resin, a polystyrene-based resin, a polymer antistatic agent and a styrene-based elastomer. In the mixed resin composition, the polyethylene-based resin forms a continuous phase, and the polystyrene-based resin and the polymer antistatic agent independently form disperse phases dispersed in the continuous phase.SELECTED DRAWING: None |
