PROBLEM TO BE SOLVED: To provide a multilayer sheet for heat molding more excellent in adhesiveness.SOLUTION: A multilayer sheet 1 for thermoforming has a foam layer 10 formed of a thermoplastic resin containing a polystyrene resin and a non-foam layer 20 which is provided on one surface of the foam layer and is formed of a polyolefin resin. The foam layer 10 has a glass transition temperature of 110°C or higher, and the non-foam layer 20 has a melting point of 150-165°C, melt viscosity at 180°C at a strain rate of 20 sof 2,500-4,000 Pa s, and melt viscosity at a strain rate of 1,000 sof 200-350 Pa s.SELECTED DRAWING: Figure 1 |
