SOLUTION: The blow molded article made of the polyester has a coating layer of a polyester (A) on the outer surface. The coating layer contains inorganic particles (B) having an average particle diameter of 10-1,000 nm in an amount of 1-30 wt.% based on the polyester (A). The layer is removable with hot water of 60-100 deg.C or with an alkaline aqueous solution of pH 10 or above. |
