PROBLEM TO BE SOLVED: To provide a sheet for thermoforming which is suitably used as food packaging container cold-stored under a low temperature, about 0-5°C, and a food packaging container cold-stored at a temperature equal to or below 0°C. SOLUTION: The sheet for thermoforming contains a propylene-ethylene block copolymer (A) having a melt flow rate (MFR;ASTM D1238, 230°C, 2.16 kg load) of 0.1-20 g/10 min, a melting point measured by a differential scanning calorimeter (DSC) of 145-170°C, 90-70 wt.% of a room temperature n-decane-insoluble portion (D<SB>insol</SB>) fulfilling a specific requirement and 10-30 wt.% of a room temperature n-decane-soluble portion (D<SB>sol</SB>) fulfilling a specific requirement.
