A colorless plastic bottle for nail polish or the like, and a method of making such a bottle. The bottle is blow molded from a color-free barrier resin such as a rubber modified acrylonitrile-methylacrylate copolymer. Tinting to compensate for inherent coloration is performed during melting in a reciprocating screw injection unit. By close control of processing temperature and injection and molding conditions a transparent bottle free of color unevenness or burns is obtained. |
