Summary:PURPOSE:To provide a multi-layered plastic vessel with good function and fine appearance as a surface luster and light-shading plastic vessel. CONSTITUTION:The plastic vessel is made of, at least, three layers and characterized as having non-colored polyplopylene resin in its outermost layer, and laminating a polypropylene resin layer containing a masking pigment and a polypropylene layer containing a shading pigment in its inside. The shading pigment is a carbon black substance, or a mixture of other pigments, and the multi-layered plastic vessel has the shading layer in the thinnest wall part of the vessel, satisfying CXT>=0.1 [herein, C shows a content of carbon black (wt.%), T is the wall thickness of the shading layer (mm)], and further blending of a vessel recycling material with the polypropylene resin layer containing a shading pigment is processed.
