摘要：
The present invention provides a method for producing a container for foods which can suppress occurrences of wrinkles and blisters, and can produce a container for foods having depth and being excellent in heat insulating properties, with the use of a supercritical injection molding method. The method for producing the container for foods according to the present invention is a method for producing the container having depth, by injection molding a molten resin that contains a supercritical fluid and a resin composition, into a cavity in a metal mold, wherein the cavity includes a first region that forms an underside portion of the container for foods having depth, a second region that forms a curved side portion, and a third region that forms a lateral side portion, from a resin injection port toward a flow end, and wherein the mold surfaces that face the cavity of the second region and the third region have an arithmetic mean roughness of 0.5 µm or larger and 10 µm or smaller, and a ten-point mean roughness of 2 µm or larger and 60 µm or smaller.
