A coinjection molding apparatus is disclosed that provides first and second material melt streams to a nozzle. The nozzle defines a first material melt passage for receiving the first material melt stream, a second material melt passage for receiving the second material melt stream and an outer layer melt passage, which receives a portion of the first material melt stream from the first material melt passage. The first material melt stream from the first material melt passage forms an inner layer of a molded article, the second material melt stream from the second material melt passage forms a core layer of the molded article, and the first material melt stream from the outer layer melt passage forms an outer layer of the molded article, wherein the three melt streams combine prior to entering a mold cavity.
