Disclosed is a deep-drawing packaging container comprising a lid member comprising a first thermally shrinkable multilayered film and a bottom member comprising a second thermally shrinkable multilayered film. The packaging container is deep-drawing-molded so that the drawing ratio in the lid member (D) and that in the bottom member (D) satisfy the following requirements: D= 1.1 to 4.0, D = 1.5 to 5.0, and (D/D) = 1.05 to 4.55. In the packaging container, the boiling water shrinkage ratio in a vertical direction (S) and that in a lateral direction (S) of the first thermally shrinkable multilayered film and the boiling water shrinkage ratio in a vertical direction (S) and that in a lateral direction (S) of the second thermally shrinkable multilayered film satisfy the following requirements: S = 5 to 40%, S = 5 to 40%, S = 2 to 25%, S = 2 to 25%, (S/S) = 1.2 to 12, and (S/S) = 1.2 to 12 [wherein the boiling water shrinkage ratio refers to a shrinkage ratio (%) as determined after immersing an undrawn thermally shrinkable multilayered film in boiling water of 90ºC for 10 seconds.] |
