Thermoforming sheets and molded containers

Abstract

To provide a thermoforming sheet and a molded container that have an excellent elastic modulus, use a small amount of resin, and have impact resistance in a freezing environment such as -30°C.SOLUTION: There is provided a thermoforming sheet (1) having a base layer (2) containing an inorganic filler and a polypropylene-based resin, in which the base layer (2) contains an inorganic filler containing talc and calcium carbonate in an amount of 20 to 30 mass% relative to the base layer (2), a mass composition ratio of the talc to the calcium carbonate is 50 / 50 to 75 / 25, an amount of the talc is 12 to 18 mass% of the base layer (2), an average particle diameter (D50) of the talc is 3 to 7 μm, the polypropylene resin is mainly composed of block polypropylene, and has a tensile modulus of elasticity in at least one of MD and TD of 1500 MPa or more, and a DuPont 50% breaking energy at a test temperature (-30°C) of 1.5 J or more.SELECTED DRAWING: Figure 1
