Abstract: This invention provides a plastic container characterized in that an expanded layer comprising expanded cells having a flat shape with an average major axis of not more than 400 ?m and an average aspect ratio (L/t) of not less than 6 as viewed in cross section of the container wall along the maximum stretch direction, which are oriented in the stretch direction and are distributed so as to be superimposed on top of each other in the thickness-wise direction, is formed within the container wall. In this container, expanded cells having a flat shape are distributed so as to orient in a given direction and, thus, has light shielding properties and has a pearl-like appearance, that is, has a very high commercial value. Further, since any colorant is not contained, the suitability for recycling is excellent.

Abstract: [Problems] To provide a foamed plastic container in which the cell diameters are varying along a gradient so will not to decrease the content protection performance, quite differently from the foamed cells distributed in the conventional foamed containers. [Means for Solution] The foamed plastic container has a container wall 10 formed by using a plastic material and in which foamed cells 1 are distributed, the lengths of the foamed cells in the surface direction of the container wall 10 decreasing from the outer surface of the container toward the inner surface thereof.
