PROBLEM TO BE SOLVED: To provide a multilayer sheet for thermoforming capable of thermoforming a container for microwave oven heating which is excellent in heat resistance, heat insulating properties and oil resistance and suppresses the generation of a blister when heated by a microwave oven and to provide a container for microwave oven heating obtained from the multilayer sheet for thermoforming.SOLUTION: There is provided a multilayer sheet for thermoforming having a specific thickness which is formed by laminating and adhering a polyolefin-based resin film layer through a rubber-modified polystyrene resin layer laminated and adhered by extrusion lamination on one surface of a foamed sheet using a styrene-(meth)acrylic acid copolymer as the base resin. The rubber-modified polystyrene resin layer is constituted of a rubber-modified polystyrene having a rubber particle diameter of 1.5 μm or less or a rubber-modified polystyrene having a rubber particle diameter of exceeding 1.5 μm and 2.5 μm or less and a gel content of 28% or more, the apparent density of the foamed sheet is in a specific range and the basis weight of the rubber-modified polystyrene resin layer is in a specific range. |
