PROBLEM TO BE SOLVED: To provide a deep-drawn polypropylene-based heat molding container withstanding retort treatment.SOLUTION: The heat molding container is obtained by a solid-phase pressure forming by using a polypropylene-based sheet. A main layer of the sheet comprises a propylene-based resin composition (X) which includes a propylene-based resin (A) of 50 to 99 wt.% and inorganic filler (B) 50 to 1 wt.% when the sum of the propylene-based resin (A) and the inorganic filler (B) is 100 wt.%., the resin (A) and the filler (B) satisfying the following requirements (A1) and (A2). The heat molding container is formed by deep-drawing so that a ratio of the depth of the container to the bore diameter thereof is 1.0 or more. The requirements (A1): a melt flow rate (MFR) is 0.3 to 3.0 g/10 min. The requirements (A2): a melt peak temperature measured by differential scanning calorimeter (DSC) is 160°C or more. |
